Angkor Wat is located about 7 kilometers north of Siem Reap provincial town along Komai or Charles De Gaul Road. The temple was built in the early 12th century during the reign of King Suryavarman II2 (AD 1113-1150) is unrivaled in its beauty and state of preservation. It is an expression of Khmer art at its highest point of development.Some believed Angkor Wat was designed by Divakaraandita, the chief adviser and minister of the king, dedicating to Vishnu Brahmanism. The Khmers attribute the building of Angkor Wat to the divine architect Visvakarman. There has been considerable debate amongst scholars as to whether Angkor Wat was built as a temple or a tomb. Angkor Wat, according to Cœdés, is a replica of the universe in stone and represents an earthly model of the monument symbolizing the mythical Mount Meru, situated at the peaks of Meru, the outer wall to the mountains at the edge of the world, and the surrounding moat in the oceans beyond.

Glasses (also called eyeglasses or spectacles) are frames bearing lenses worn in front of the eyes, normally for vision correction, eye protection, or for protection from UV rays.

Modern glasses are typically supported by pads on the bridge of the nose and by temples placed over the ears. Historical types include the pince-nez, monocle, lorgnette, and scissors-glasses.

Eyeglass lenses are commonly made from plastic, including CR-39 and polycarbonate. These materials reduce the danger of breakage and weigh less than glass lenses. Some plastics also have more advantageous optical properties than glass, such as better transmission of visible light and greater absorption of ultraviolet light.^[1] Some plastics have a greater index of refraction than most types of glass; this is useful in the making of corrective lenses shaped to correct various vision abnormalities such as myopia, allowing thinner lenses for a given prescription. Newer plastic lenses, called izon, can also correct for the higher order aberrations that naturally occur in the surface of our eye.^{[citation needed]} These lenses create sharper vision for the people who have problems with sight and help with the halos, starbursts, and comet-tails often associated with night time driving glare.^{[citation needed]} Wavefront guided LASIK surgery also corrects for the higher order aberrations.

Scratch-resistant coatings can be applied to most plastic lenses giving them similar scratch resistance to glass. Hydrophobic coatings designed to ease cleaning are also available, as are anti-reflective coatings intended to reduce glare, improve night vision and make the wearer’s eyes more visible.^[2]

CR-39 lenses are the most common plastic lenses due to their low weight, high scratch resistance, and low transparency for ultra violet and infrared radiation. Polycarbonate and Trivex lenses are the lightest and most shatter-resistant, making them the best for impact protection,^[1] though polycarbonate offers poor optics due to high dispersion, having a low Abbe number of 31.

Not all glasses are designed solely for vision correction but are worn for protection, viewing visual information (such as stereoscopy) or simply just for aesthetic or fashion values. Safety glasses are a kind of eye protection against flying debris or against visible and near visible light or radiation. Sunglasses allow better vision in bright daylight, and may protect against damage from high levels of ultraviolet light.

History of eyeglasses

Precursors

The earliest historical reference to magnification dates back to ancient Egyptian hieroglyphs in the 8th century BC, which depict “simple glass meniscal lenses“. The earliest written record of magnification dates back to the 1st century AD, when Seneca the Younger, a tutor of Emperor Nero, wrote: “Letters, however small and indistinct, are seen enlarged and more clearly through a globe or glass filled with water”.^[3] Emperor Nero is also said to have watched the gladiatorial games using an emerald as a corrective lens.^[4]

Corrective lenses were said to be used by Abbas Ibn Firnas in the 9th century,^[5] who had devised a way to produce very clear glass. These glasses could be shaped and polished into round rocks used for viewing and were known as reading stones. The earliest evidence of “a magnifying device, a convex lens forming a magnified image,” dates back the Book of Optics published by Alhazen in 1021. Its translation into Latin in the 12th century was instrumental to the invention of eyeglasses in 13th century Italy.^[3]

Sunglasses, in the form of flat panes of smoky quartz, protected the eyes from glare and were used in China in the 12th century or possibly earlier. However, they did not offer any corrective benefits.^[6]

Invention of eyeglasses

The ‘Glasses Apostle’ by Conrad von Soest (1403)

Around 1284 in Italy, Salvino D’Armate is credited with inventing the first wearable eye glasses.^[7] The earliest pictorial evidence for the use of eyeglasses, however, is Tomaso da Modena’s 1352 portrait of the cardinal Hugh de Provence reading in a scriptorium. Another early example would be a depiction of eyeglasses found north of the Alpes in an altarpiece of the church of Bad Wildungen, Germany, in 1403.

Many theories abound for who should be credited for the invention of traditional eyeglasses. In 1676, Francesco Redi, a professor of medicine at the University of Pisa, wrote that he possessed a 1289 manuscript whose author complains that he would be unable to read or write were it not for the recent invention of glasses. He also produced a record of a sermon given in 1305, in which the speaker, a Dominican monk named Fra Giordano da Rivalto, remarked that glasses had been invented less than twenty years previously, and that he had met the inventor. Based on this evidence, Redi credited another Dominican monk, Fra Alessandro da Spina of Pisa, with the re-invention of glasses after their original inventor kept them a secret, a claim contained in da Spina’s obituary record.^[8]

Other stories, possibly legendary, credit Roger Bacon with the invention. Bacon is known to have made one of the first recorded references to the magnifying properties of lenses in 1262,^[9] though this was predated by Alhazen‘s Book of Optics in 1021.^[3] Bacon’s treatise De iride (“On the Rainbow”), which was written while he was a student of Robert Grosseteste, no later than 1235, mentions using optics to “read the smallest letters at incredible distances”. While the exact date and inventor may be forever disputed, it is almost certain that spectacles were invented between 1280 and 1300 in Italy. These early spectacles had convex lenses that could correct both hyperopia (farsightedness), and the presbyopia that commonly develops as a symptom of aging. Nicholas of Cusa is believed to have discovered the benefits of concave lens in the treatment of myopia (nearsightedness). However, it was not until 1604 that Johannes Kepler published in his treatise on optics and astronomy, the first correct explanation as to why convex and concave lenses could correct presbyopia and myopia.

Later developments

A portrait of Francisco de Quevedo y Villegas, 1580–1645

The American scientist Benjamin Franklin, who suffered from both myopia and presbyopia, invented bifocals in 1784 to avoid having to regularly switch between two pairs of glasses.^[10] The first lenses for correcting astigmatism were constructed by the British astronomer George Airy in 1825.^[10]

Over time, the construction of spectacle frames also evolved. Early eyepieces were designed to be either held in place by hand or by exerting pressure on the nose (pince-nez). Girolamo Savonarola suggested that eyepieces could be held in place by a ribbon passed over the wearer’s head, this in turn secured by the weight of a hat. The modern style of glasses, held by temples passing over the ears, was developed in 1727 by the British optician Edward Scarlett. These designs were not immediately successful, however, and various styles with attached handles such as “scissors-glasses” and lorgnettes remained fashionable throughout the 18th and into the early 19th century.

In the early 20th century, Moritz von Rohr at Zeiss (with the assistance of H. Boegehold and A. Sonnefeld^[11]), developed the Zeiss Punktal spherical point-focus lenses that dominated the eyeglass lens field for many years.

Despite the increasing popularity of contact lenses and laser corrective eye surgery, glasses remain very common, as their technology has improved. For instance, it is now possible to purchase frames made of special memory metal alloys that return to their correct shape after being bent. Other frames have spring-loaded hinges. Either of these designs offers dramatically better ability to withstand the stresses of daily wear and the occasional accident. Modern frames are also often made from strong, light-weight materials such as titanium alloys, which were not available in earlier times.

Modern Developments in the UK In 1958 The General Optical Council was created by Parliament in 1958 through the Opticians Act.

Before the Opticians Act, optometry and dispensing optics were not regulated professions. It was not until after the introduction of the National Health Service in 1948 that the then Health Minister and the Secretary of State for Scotland set up a Committee to determine whether a regulatory body should be created.

Some of the major high street opticians nowadays are Dollond & Aitchison, Boots Group, Specsavers & Vision Express. In 2005 Prescription glasses were sold online for the first time thus giving people the chance to bypass high street opticians and buy their glasses directly from the manufacturer, usually paying far less. Major firms in the online glasses industry today are Next Vision, Glasses Direct, Specsavers and Select Specs.

Types

Corrective

Corrective lenses are used to correct refractive errors of the eye by modifying the effective focal length of the lens in order to alleviate the effects of conditions such as; nearsightedness (myopia), farsightedness (hyperopia) or astigmatism. Another common condition in older patients is presbyopia which is caused by the eye’s crystalline lens losing elasticity, progressively reducing the ability of the lens to accommodate (i.e. to focus on objects close to the eye).

The power of a lens is generally measured in diopters. Over-the-counter reading glasses are typically rated at +1.00 to +3.25 diopters. Glasses correcting for myopia will have negative diopter strengths. Prescription lenses, made to conform to the prescription of an ophthalmologist or optometrist, are used to make prescription glasses, which are then verified correct using a professional lensmeter.

Pinhole glasses are a type of corrective glasses which do not use a conventional lens and are claimed to help correct the eye’s refractive error without introducing the image distortion of traditional lens-based glasses.

Safety

Safety glasses are usually made with shatter-resistant plastic lenses to protect the eye from flying debris. Although safety lenses may be constructed from a variety of materials of various impact resistance, certain standards suggest that they maintain a minimum 1 millimeter thickness at the thinnest point, regardless of material. Safety glasses can vary in the level of protection they provide. For example, those used in medicine may be expected to protect against blood splatter while safety glasses in a factory might have stronger lenses and a stronger frame with additional shields at the temples. The lenses of safety glasses can also be shaped for correction.

Safety glasses with side shields

The American National Standards Institute has established standard ANSI Z87.1 for safety glasses in the United States, and similar standards have been established elsewhere.

OSHA provides guidance on the type of safety eyewear that should be used for a particular application.

Some safety glasses are designed to fit over corrective glasses or sunglasses. They may provide less eye protection than goggles or other forms of eye protection, but their light weight increases the likelihood that they will actually be used. Modern safety glasses tend to be given a more stylish design in order to encourage their use. Corrective glasses with plastic lenses can be used in the place of safety glasses in many environments; this is one advantage that they have over contact lenses.

There are also safety glasses for welding, which are styled like wraparound sunglasses, but with much darker lenses, for use in welding where a full sized welding helmet is inconvenient or uncomfortable. These are often called “flash goggles”, because they provide protection from welding flash.

Worker safety eyewear is available in various lens colors and/or with coatings to protect or enable eyesight in different lighting conditions, particularly when outdoors.

Nylon frames are usually used for protection eyewear for sports because of their lightweight and flexible properties. They are able to bend slightly and return to their original shape instead of breaking when pressure is applied to them. Nylon frames can become very brittle with age and they can be difficult to adjust.

Sunglasses

Sunglasses may be made with either prescription or non-prescription lenses that are darkened to provide protection against bright visible light and, possibly, ultraviolet (UV) light. Photochromic lenses, which are photosensitive, darken when struck by UV light.

Light polarization is an added feature that can be applied to sunglass lenses. Polarization filters remove horizontally polarized rays of light, which can cause glare. Polarized sunglasses allow wearers to see into water when normally glare or reflected light would be seen. Polarized sunglasses may present some difficulties for pilots since reflections from water and other structures often used to gauge altitude may be removed, or instrument readings on liquid crystal displays may be blocked.

Yellow lenses increase color contrast and improve depth perception. Brown lenses are common among golfers, but cause color distortion.^{[citation needed]} Blue, purple, and green lenses offer no real benefits to vision enhancement, and are mainly cosmetic.^{[citation needed]} Some sunglasses with interchangeable lenses have optional clear lenses to protect the eyes during low light or night time activities and a colored lens with UV protection for times where sun protection is needed.

Sunglasses are often worn just for aesthetic purposes, or simply to hide the eyes. Examples of sunglasses that were popular for these reasons include teashades and mirrorshades.

3D glasses

The illusion of three dimensions on a two dimensional surface can be created by providing each eye with different visual information. Classic 3D glasses create the illusion of three dimensions when viewing specially prepared images. The classic 3D glasses have one red lens and one blue or cyan lens. 3D glasses made of cardboard and plastic are distributed at 3D movies. Another kind of 3D glasses uses polarized filters, with one lens polarized vertically and the other horizontally, with the two images required for stereo vision polarized the same way. Polarized 3D glasses allow for color 3D, while the red-blue lenses produce a dull black-and-white picture with red and blue fringes.

One kind of electronic 3D spectacles uses electronic shutters, while virtual reality glasses and helmets have separate video screens for each eye. A 3D effect can also be produced using LCD shutter glasses.^[12]

Reading glasses

Magnifying lenses or generic spectacles that are used to treat mild presbyopia and hyperopia can be bought off the shelf. The use of individual prescriptions as determined by a qualified optician results in better optical performance of reading glasses.

Bifocals, trifocals and progressive lenses

As people age, their ability to focus is lessened and many decide to use multiple-focus lenses, bifocal or even trifocal to cover all the situations in which they use their sight. Traditional multifocal lenses have two or three distinct horizontal viewing areas, each requiring a conscious effort of refocusing. Some modern multifocal lenses, such as progressive lenses (known as “no-line bifocals”), give a smooth transition between these different focal points, unnoticeable by most wearers, while other glasses have lenses specifically intended for use with computer monitors at a fixed distance. People may have several pairs of glasses, one for each task or distance, with specific glasses for reading, computer use, television watching, and writing.

Extreme magnification (bioptics)

A form of glasses with extreme magnification to improve the distance vision of those with severe eyesight impairment, especially people with albinism, are known as bioptics or a bioptic telescope. They may take the form of self-contained glasses that resemble goggles or binoculars, or may be attached to existing glasses.

Fashion

Glasses can be a major part of personal image and expression, from Groucho Marx and Buddy Holly to the extravagance of Elton John and Dame Edna Everage.

For some celebrities, glasses form part of their identity. United States Senator Barry Goldwater continued to wear lensless horn-rimmed glasses after being fitted with contact lenses because he was not recognizable without his trademark glasses. British soap star Anne Kirkbride had the same problem: her character on Coronation Street, Deirdre Barlow, became so well-known for her big frames that she was expected to wear them at social gatherings and in international tours, even though Kirkbride has always worn contact lenses. Comedian Drew Carey continued to wear glasses for the same reason after getting corrective laser eye surgery. British comedic actor Eric Sykes, who became profoundly deaf as an adult, wears glasses that contain no lenses; they are actually a bone-conducting hearing aid. Masaharu Morimoto wears glasses to separate his professional persona as a chef from his stage persona as Iron Chef Japanese. John Lennon wore his round-lens ‘Windsor’ spectacles from some of his time with the Beatles to his murder in 1980. The rock band Weezer is known for some of the members wearing thick-rimmed glasses.

Browline glasses were the standard for men in the 1950s and 1960s.

In popular culture, glasses were all the disguise Superman and Wonder Woman needed to hide in plain view as alter egos Clark Kent and Diana Prince, respectively. An example of halo effect is seen in the stereotype that those who wear glasses are intelligent or, especially in teen culture, even geeks and nerds. Some people who find that wearing glasses may look ‘nerdy’ turn to contact lenses or laser eye surgery, especially under peer pressure.

Another unpopular aspect of glasses is their inconvenience. Even through the creation of light frames, such as those made of titanium, very flexible frames, and new lens materials and optical coatings, glasses can still cause problems during rigorous sports. The lenses can become greasy or trap vapour when eating hot food, swimming, walking in rain or rapid temperature changes (such as walking into a warm building from cold temperatures outside), reducing visibility significantly. Scraping, fracturing, or breakage of the lenses require time-consuming and costly professional repair, though modern plastic lenses are almost indestructible and very scratch-resistant.

Rimless style

Three-piece rimless and semi-rimless glasses are common variations that differ from regular glasses in that their frames do not completely encircle the lenses. Three-piece rimless glasses have no frame around the lenses, and the bridge and temples are mounted directly onto the lenses. Semi-rimless (or half-rimless) glasses have a frame that only partially encircles the lenses (commonly the top portion). When the style was first introduced in the 1930s, lenses were screwed directly to the front of the frame; most modern variations feature the lenses held inside of the frame by high strength nylon wire,^[13] although the semi-rimless style has been around since at least the 1940s. A rare and currently noncommercial variation are rimless and frameless glasses attached to a piercing at the bridge of a wearers nose.^[14] Such glasses have the visual look of the pince-nez.

Glazing

Spectacle lenses are edged into the frame’s rim using glazing machines operated by ophthalmic technicians. The edging process begins with a trace being taken of the frame’s eye shape. In earlier days the trace was replicated onto a plastic pattern called a former. Nowadays the process is patternless and the shape is sent to the edger electronically.

The lens, in the form of a round uncut,^{[clarification needed]} is positioned in the correct manner to match the prescription and a block is stuck to the lens and that block fits into a chuck in the edging machine. A diamond-coated wheel spins as the edger replicates the frame’s eye-shape to the uncut lens. A V-shaped bevel is applied to allow the edge of the lens to fit into the frame rim.

Etymology

Corinthia Grand Hotel Royal, Budapest, Hungary

The word hotel is derived from the French hôtel (coming from hôte meaning host), which referred to a French version of a townhouse or any other building seeing frequent visitors, rather than a place offering accommodation. In contemporary French usage, hôtel now has the same meaning as the English term, and hôtel particulier is used for the old meaning. The French spelling, with the circumflex, was also used in English, but is now rare. The circumflex replaces the ‘s’ found in the earlier hostel spelling, which over time took on a new, but closely related meaning. Grammatically, hotels usually take the definite article – hence “The Astoria Hotel” or simply “The Astoria”.

Classification

A budget hotel in Malaysia

The cost and quality of hotels are usually indicative of the range and type of services available. Due to the enormous increase in tourism worldwide during the last decades of the 20th century, standards, especially those of smaller establishments, have improved considerably.^{[citation needed]} For the sake of greater comparability, rating systems have been introduced, with the one to five stars classification being most common^{[citation needed]} and with higher star ratings indicating more luxury. Hotels are independently assessed in traditional systems and these rely heavily on the facilities provided.^{[citation needed]} Some consider this disadvantageous to smaller hotels whose quality of accommodation could fall into one class but the lack of an item such as an elevator would prevent it from reaching a higher categorization.^{[citation needed]} In some countries, there is an official body with standard criteria for classifying hotels, but in many others there is none. There have been attempts at unifying the classification system so that it becomes an internationally recognized and reliable standard^{[citation needed]} but large differences exist in the quality of the accommodation and the food within one category of hotel, sometimes even in the same country. The American Automobile Association (AAA) and their affiliated bodies use diamonds instead of stars to express hotel and restaurant ratings levels.

Historic hotels

Some hotels have gained their renown through tradition, by hosting significant events or persons, such as Schloss Cecilienhof in Potsdam, Germany, which derives its fame from the Potsdam Conference of the World War II allies Winston Churchill, Harry Truman and Joseph Stalin in 1945. The Taj Mahal Palace & Tower in Mumbai is one of India‘s most famous and historic hotels because of its association with the Indian independence movement. Some establishments have given name to a particular meal or beverage, as is the case with the Waldorf Astoria in New York City, United States where the Waldorf Salad was first created or the Hotel Sacher in Vienna, Austria, home of the Sachertorte. Others have achieved fame by association with dishes or cocktails created on their premises, such as the Hotel de Paris where the crêpe Suzette was invented or the Raffles Hotel in Singapore, where the Singapore Sling cocktail was devised.

Hôtel Ritz in Paris, France

A number of hotels have entered the public consciousness through popular culture, such as the Ritz Hotel in London, United Kingdom, through its association with Irving Berlin’s song, ‘Puttin’ on the Ritz‘. The Algonquin Hotel in New York City is famed as the meeting place of the literary group, the Algonquin Round Table, and Hotel Chelsea, also in New York City, has been the subject of a number of songs and the scene of the stabbing of Nancy Spungen (allegedly by her boyfriend Sid Vicious). The Waldorf Astoria and Statler hotels in New York City are also immortalized in the names of Muppets Statler and Waldorf.

The luxurious Grand Hotel Europe in Saint Petersburg, Russia achieved fame with its inclusion in the James Bond film GoldenEye.

Unusual hotels

U.S. City Chicago’s Magnificent Mile has hosted many skyscraper hotels such as the Allerton Hotel.

Many hotels can be considered destinations in themselves, by dint of unusual features of the lodging or its immediate environment:

Treehouse hotels

Some hotels are built with living trees as structural elements, for example the Costa Rica Tree House in the Gandoca-Manzanillo Wildlife Refuge, Costa Rica; the Treetops Hotel in Aberdare National Park, Kenya; the Ariau Towers near Manaus, Brazil, on the Rio Negro in the Amazon; and Bayram’s Tree Houses in Olympos, Turkey.

Cave hotels

Desert Cave Hotel in Coober Pedy, South Australia and the Cuevas Pedro Antonio de Alarcón (named after the author) in Guadix, Spain, as well as several hotels in Cappadocia, Turkey, are notable for being built into natural cave formations, some with rooms underground.

Capsule hotels

Capsule hotels are a type of economical hotel that are found in Japan, where people sleep in stacks of rectangular containers.

Ice and snow hotels

The Ice Hotel in Jukkasjärvi, Sweden, and the Hotel de Glace in Duschenay,­ Canada, melt every spring and are rebuilt each winter; the Mammut Snow Hotel in Finland is located within the walls of the Kemi snow castle; and the Lainio Snow Hotel is part of a snow village near Ylläs, Finland.

Garden hotels

Garden hotels, famous for their gardens before they became hotels, include Gravetye Manor, the home of garden designer William Robinson, and Cliveden, designed by Charles Barry with a rose garden by Geoffrey Jellicoe.

Underwater hotels

Some hotels have accommodation underwater, such as Utter Inn in Lake Mälaren, Sweden. Hydropolis, project cancelled 2004 in Dubai, will have suites on the bottom of the Persian Gulf, and Jules Undersea Lodge in Key Largo, Florida requires scuba diving to access its rooms.

Other unusual hotels

• The Library Hotel in New York City, United States is unique in that each of its ten floors are assigned one category from the Dewey Decimal System.
• The Burj al-Arab hotel in Dubai, United Arab Emirates, built on an artificial island, is structured in the shape of a boat’s sail.
• The former ocean liner RMS Queen Mary in Long Beach, California, United States uses its first-class staterooms as a hotel.
• The Jailhotel Löwengraben in Lucerne, Switzerland is a converted prison now used as a hotel.
• The Luxor, a hotel and casino on The Las Vegas Strip in Paradise, Nevada, United States due to its pyramidal structure.
• The Liberty Hotel in Boston, United States used to be the Charles Street Jail.

Resort hotels

The Luxor Hotel in Las Vegas, United States, a resort hotel serving an attached casino.

Some hotels are built specifically to create a captive trade, example at casinos and holiday resorts. Though of course hotels have always been built in popular desinations, the defining characteristic of a resort hotel is that it exists purely to serve another attraction, the two having the same owners.

In Las Vegas, Nevada there is a tradition of one-upmanship with extravagant themed hotels in a concentrated area known as the Las Vegas Strip. This trend now has extended to other resorts worldwide, but the concentration in Las Vegas is still the world’s highest: nineteen of the world’s twenty-five largest hotels by room count are on the Strip, with a total of over 67,000 rooms.^[1]

In Europe Center Parcs might be considered a chain of resort hotels, since the sites are largely man-made (though set in natural surroundings such as country parks) with captive trade, whereas holiday camps such as Butlins and Pontin’s are probably not considered as resort hotels, since they are set at traditional holiday destinations which existed before the camps.

Railway hotels

Frequently, expanding railway companies built grand hotels at their termini, such as the Midland Hotel, Manchester next to the former Manchester Central Station and in London the ones above St Pancras railway station and Charing Cross railway station also in London is the the Chiltern Court Hotel above Baker Street tube station and Canada’s grand railway hotels. They are or were mostly, but not exclusively, used by those travelling by rail.

From Wikipedia, the free encyclopedia

Angkor Wat (or Angkor Vat) (Khmer: អង្គរវត្ត), is a temple complex at Angkor, Cambodia, built for the king Suryavarman II in the early 12th century as his state temple and capital city. As the best-preserved temple at the site, it is the only one to have remained a significant religious centre since its foundation—first Hindu, dedicated to Vishnu, then Buddhist. The temple is the epitome of the high classical style of Khmer architecture. It has become a symbol of Cambodia, appearing on its national flag, and it is the country’s prime attraction for visitors.

Angkor Wat combines two basic plans of Khmer temple architecture: the temple mountain and the later galleried temple, based on early South Indian Hindu architecture, with key features such as the Jagati. It is designed to represent Mount Meru, home of the devas in Hindu mythology: within a moat and an outer wall 3.6 kilometres (2.2 mi) long are three rectangular galleries, each raised above the next. At the centre of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west; scholars are divided as to the significance of this. The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs and for the numerous devatas (guardian spirits) adorning its walls.

The modern name, Angkor Wat, means “City Temple”: Angkor is a vernacular form of the word nokor which comes from the Sanskrit word nagara meaning capital. wat is the Khmer word for temple. Prior to this time the temple was known as Preah Pisnulok, after the posthumous title of its founder, Suryavarman II.[1]

History

Angkor Wat is the southernmost temple of Angkor’s main group of sites.

An 1866 photograph of Angkor Wat by Emile Gsell

Angkor Wat lies 5.5 km north of the modern town of Siem Reap, and a short distance south and slightly east of the previous capital, which was centred on the Baphuon. It is in an area of Cambodia where there is an important group of ancient structures. It is the southernmost of Angkor’s main sites.

The initial design and construction of the temple took place in the first half of the 12th century, during the reign of Suryavarman II (ruled 1113 – c. 1150), Dedicated to Vishnu, it was built as the king’s state temple and capital city. As neither the foundation stela nor any contemporary inscriptions referring to the temple have been found, its original name is unknown, but it may have been known as Vrah Vishnulok after the presiding deity. Work seems to have ended shortly after the king’s death, leaving some of the bas-relief decoration unfinished. In 1177, approximately 27 years after the death of Sulyavarman II, Angkor was sacked by the Chams, the traditional enemies of the Khmer. Thereafter the empire was restored by a new king, Jayavarman VII, who established a new capital and state temple (Angkor Thom and the Bayon respectively) a few kilometres to the north.

In the late 13th century, King Jayavarman VIII, who was Hindu, was deposed by his son in law, Srindravarman. Srindravarman had spent the previous 10 years in Sri Lanka becoming ordained as a Buddhist monk. Hence, the new King decided to convert the official religion of the empire from Hindu to Buddhist. Given the constant political corruption of the time, citizens were quick to follow a faith founded on tranquility without a need for material gain and power. This made the conversion relatively easy. Hence, Angkor Wat was converted from Hindu to Theravada Buddhist use, which continues to the present day. Angkor Wat is unusual among the Angkor temples in that although it was somewhat neglected after the 16th century it was never completely abandoned, its preservation being due in part to the fact that its moat also provided some protection from encroachment by the jungle.

One of the first Western visitors to the temple was Antonio da Magdalena, a Portuguese monk who visited in 1586 and said that it “is of such extraordinary construction that it is not possible to describe it with a pen, particularly since it is like no other building in the world. It has towers and decoration and all the refinements which the human genius can conceive of”.However, the temple was popularised in the West only in the mid-19th century on the publication of Henri Mouhot‘s travel notes. The French explorer wrote of it:

“One of these temples—a rival to that of Solomon, and erected by some ancient Michelangelo—might take an honourable place beside our most beautiful buildings. It is grander than anything left to us by Greece or Rome, and presents a sad contrast to the state of barbarism in which the nation is now plunged.”

Mouhot, like other early Western visitors, was unable to believe that the Khmers could have built the temple, and mistakenly dated it to around the same era as Rome. The true history of Angkor Wat was pieced together only from stylistic and epigraphic evidence accumulated during the subsequent clearing and restoration work carried out across the whole Angkor site.

There were no ordinary dwellings or houses or other signs of settlement including cooking utensils weapons or items of clothing usually found at ancient sites. Instead there is the evidence of the monuments themselves.

Angkor Wat required considerable restoration in the 20th century, mainly the removal of accumulated earth and vegetation. Work was interrupted by the civil war and Khmer Rouge control of the country during the 1970s and 1980s, but relatively little damage was done during this period other than the theft and destruction of mostly post-Angkorian statues.

The temple has become a symbol of Cambodia, and is a source of great national pride. A depiction of Angkor Wat has been a part of Cambodian national flags since the introduction of the first version circa 1863. In January 2003 riots erupted in Phnom Penh when a false rumour circulated that a Thai soap opera actress had claimed that Angkor Wat belonged to Thailand.

Angkor Wat, located at 13°24′45″N 103°52′0″E / 13.4125°N 103.86667°E / 13.4125; 103.86667Coordinates: 13°24′45″N 103°52′0″E / 13.4125°N 103.86667°E / 13.4125; 103.86667, is a unique combination of the temple mountain, the standard design for the empire’s state temples, the later plan of concentric galleries, and influences from Orissa and the Chola of Tamil Nadu, India. The temple is a representation of Mount Meru, the home of the gods: the central quincunx of towers symbolises the five peaks of the mountain, and the walls and moat the surrounding mountain ranges and ocean. Access to the upper areas of the temple was progressively more exclusive, with the laity being admitted only to the lowest level.

Unlike most Khmer temples, Angkor Wat is oriented to the west rather than the east. This has led many (including Glaize and George Coedès) to conclude that Suryavarman intended it to serve as his funerary temple. Further evidence for this view is provided by the bas-reliefs, which proceed in a counter-clockwise direction—prasavya in Hindu terminology—as this is the reverse of the normal order. Rituals take place in reverse order during Brahminic funeral services. The archaeologist Charles Higham also describes a container which may have been a funerary jar which was recovered from the central tower. It has been nominated by some as the greatest expenditure of energy on the disposal of a corpse. Freeman and Jacques, however, note that several other temples of Angkor depart from the typical eastern orientation, and suggest that Angkor Wat’s alignment was due to its dedication to Vishnu, who was associated with the west.

A further interpretation of Angkor Wat has been proposed by Eleanor Mannikka. Drawing on the temple’s alignment and dimensions, and on the content and arrangement of the bas-reliefs, she argues that these indicate a claimed new era of peace under king Suryavarman II: “as the measurements of solar and lunar time cycles were built into the sacred space of Angkor Wat, this divine mandate to rule was anchored to consecrated chambers and corridors meant to perpetuate the king’s power and to honor and placate the deities manifest in the heavens above.” Mannikka’s suggestions have been received with a mixture of interest and scepticism in academic circles. She distances herself from the speculations of others, such as Graham Hancock, that Angkor Wat is part of a representation of the constellation Draco.

Style

Angkor Wat is the prime example of the classical style of Khmer architecture—the Angkor Wat style—to which it has given its name. By the 12th century Khmer architects had become skilled and confident in the use of sandstone (rather than brick or laterite) as the main building material. Most of the visible areas are of sandstone blocks, while laterite was used for the outer wall and for hidden structural parts. The binding agent used to join the blocks is yet to be identified, although natural resins or slaked lime have been suggested.

Angkor Wat has drawn praise above all for the harmony of its design, which has been compared to the architecture of ancient Greece or Rome. According to Maurice Glaize, a mid-20th-century conservator of Angkor, the temple “attains a classic perfection by the restrained monumentality of its finely balanced elements and the precise arrangement of its proportions. It is a work of power, unity and style.”

Architecturally, the elements characteristic of the style include: the ogival, redented towers shaped like lotus buds; half-galleries to broaden passageways; axial galleries connecting enclosures; and the cruciform terraces which appear along the main axis of the temple. Typical decorative elements are devatas (or apsaras), bas-reliefs, and on pediments extensive garlands and narrative scenes. The statuary of Angkor Wat is considered conservative, being more static and less graceful than earlier work. Other elements of the design have been destroyed by looting and the passage of time, including gilded stucco on the towers, gilding on some figures on the bas-reliefs, and wooden ceiling panels and doors.

The Angkor Wat style was followed by that of the Bayon period, in which quality was often sacrificed to quantity. Other temples in the style are Banteay Samré, Thommanon, Chao Say Tevoda and the early temples of Preah Pithu at Angkor; outside Angkor, Beng Mealea and parts of Phanom Rung and Phimai.

Outer enclosure

The outer wall, 1024 by 802 m and 4.5 m high, is surrounded by a 30 m apron of open ground and a moat 190 m wide. Access to the temple is by an earth bank to the east and a sandstone causeway to the west; the latter, the main entrance, is a later addition, possibly replacing a wooden bridge. There are gopuras at each of the cardinal points; the western is much the largest and has three ruined towers. Glaize notes that this gopura both hides and echoes the form of the temple proper. Under the southern tower is a statue of Vishnu, known as Ta Reach, which may originally have occupied the temple’s central shrine. Galleries run between the towers and as far as two further entrances on either side of the gopura often referred to as “elephant gates”, as they are large enough to admit those animals. These galleries have square pillars on the outer (west) side and a closed wall on the inner (east) side. The ceiling between the pillars is decorated with lotus rosettes; the west face of the wall with dancing figures; and the east face of the wall with balustered windows, dancing male figures on prancing animals, and devatas, including (south of the entrance) the only one in the temple to be showing her teeth.

The Temple viewed from the northwest

The outer wall encloses a space of 820,000 square metres (203 acres), which besides the temple proper was originally occupied by the city and, to the north of the temple, the royal palace. Like all secular buildings of Angkor, these were built of perishable materials rather than of stone, so nothing remains of them except the outlines of some of the streets. Most of the area is now covered by forest. A 350 m causeway connects the western gopura to the temple proper, with naga balustrades and six sets of steps leading down to the city on either side. Each side also features a library with entrances at each cardinal point, in front of the third set of stairs from the entrance, and a pond between the library and the temple itself. The ponds are later additions to the design, as is the cruciform terrace guarded by lions connecting the causeway to the central structure.

Central structure

This model of Angkor Wat shows intact the half-galleries of the lower level and towers at the corners of the second-level galleries.

The temple stands on a terrace raised higher than the city. It is made of three rectangular galleries rising to a central tower, each level higher than the last. Mannikka interprets these galleries as being dedicated to the king, Brahma, the moon, and Vishnu. Each gallery has a gopura at each of the points, and the two inner galleries each have towers at their corners, forming a quincunx with the central tower. Because the temple faces west, the features are all set back towards the east, leaving more space to be filled in each enclosure and gallery on the west side; for the same reason the west-facing steps are shallower than those on the other sides.

The outer gallery measures 187 by 215 m, with pavilions rather than towers at the corners. The gallery is open to the outside of the temple, with columned half-galleries extending and buttressing the structure. Connecting the outer gallery to the second enclosure on the west side is a cruciform cloister called Preah Poan (the “Hall of a Thousand Buddhas”). Buddha images were left in the cloister by pilgrims over the centuries, although most have now been removed. This area has many inscriptions relating the good deeds of pilgrims, most written in Khmer but others in Burmese and Japanese. The four small courtyards marked out by the cloister may originally have been filled with water. North and south of the cloister are libraries.

Beyond, the second and inner galleries are connected to each other and to two flanking libraries by another cruciform terrace, again a later addition. From the second level upwards, devatas abound on the walls, singly or in groups of up to four. The second-level enclosure is 100 by 115 m, and may originally have been flooded to represent the ocean around Mount Meru. Three sets of steps on each side lead up to the corner towers and gopuras of the inner gallery. The very steep stairways represent the difficulty of ascending to the kingdom of the gods. This inner gallery, called the Bakan, is a 60 m square with axial galleries connecting each gopura with the central shrine, and subsidiary shrines located below the corner towers. The roofings of the galleries are decorated with the motif of the body of a snake ending in the heads of lions or garudas. Carved lintels and pediments decorate the entrances to the galleries and to the shrines. The tower above the central shrine rises 43 m to a height of 65 m above the ground; unlike those of previous temple mountains, the central tower is raised above the surrounding four. The shrine itself, originally occupied by a statue of Vishnu and open on each side, was walled in when the temple was converted to Theravada Buddhism, the new walls featuring standing Buddhas. In 1934, the conservator George Trouvé excavated the pit beneath the central shrine: filled with sand and water it had already been robbed of its treasure, but he did find a sacred foundation deposit of gold leaf two metres above ground level.

Decoration

The bas-relief of the Churning of the Sea of Milk shows Vishnu in the centre, his turtle avatar Kurma below, asuras and devas to left and right, and apsaras and Indra above.

Integrated with the architecture of the building, and one of the causes for its fame is Angkor Wat’s extensive decoration, which predominantly takes the form of bas-relief friezes. The inner walls of the outer gallery bear a series of large-scale scenes mainly depicting episodes from the Hindu epics the Ramayana and the Mahabharata. Higham has called these, “the greatest known linear arrangement of stone carving”. From the north-west corner anti-clockwise, the western gallery shows the Battle of Lanka (from the Ramayana, in which Rama defeats Ravana) and the Battle of Kurukshetra (from the Mahabharata, showing the mutual annihilation of the Kaurava and Pandava clans). On the southern gallery follow the only historical scene, a procession of Suryavarman II, then the 32 hells and 37 heavens of Hindu mythology.

Devatas are characteristic of the Angkor Wat style.

Glaize writes of;

“… those unfortunate souls who are to be thrown down to hell to suffer a refined cruelty which, at times, seems to be a little disproportionate to the severity of the crimes committed. So it is that people who have damaged others’ property have their bones broken, that the glutton is cleaved in two, that rice thieves are afflicted with enormous bellies of hot iron, that those who picked the flowers in the garden of Shiva have their heads pierced with nails, and thieves are exposed to cold discomfort.”

On the eastern gallery is one of the most celebrated scenes, the Churning of the Sea of Milk, showing 92 asuras and 88 devas using the serpent Vasuki to churn the sea under Vishnu’s direction (Mannikka counts only 91 asuras, and explains the asymmetrical numbers as representing the number of days from the winter solstice to the spring equinox, and from the equinox to the summer solstice). It is followed by Vishnu defeating asuras (a 16th-century addition). The northern gallery shows Krishna’s victory over Bana (where according to Glaize, “The workmanship is at its worst”) and a battle between the Hindu gods and asuras. The north-west and south-west corner pavilions both feature much smaller-scale scenes, some unidentified but most from the Ramayana or the life of Krishna.

Construction techniques

The stones, as smooth as polished marble, were laid without mortar with very tight joints that were sometimes hard to find. The blocks were held together by mortise and tenon joints in some cases, while in others they used dovetails and gravity. The blocks were presumably put in place by a combination of elephants, coir ropes, pulleys and bamboo scaffolding. Henri Mouhot noted that most of the blocks had holes 2.5 cm in diameter and 3 cm deep, with more holes on the larger blocks. Some scholars have suggested that these were used to join them together with iron rods, but others claim they were used to hold temporary pegs to help manoeuver them into place. The Khmer architects never made the curved arches used by the Romans. They did create a corbelled arch, but this often proved unstable and collapsed.

The monument was made out of enormous amounts of sandstone, as much as Khafre’s pyramid in Egypt (over 5 million tons). This sandstone had to be transported from Mount Kulen, a quarry approximately 25 miles (40 km) to the northeast. The stone was presumably transported by raft along the Siem Reap river. This would have to have been done with care to avoid overturning the rafts with such a large amount of weight. One modern engineer estimated it would take 300 years to complete Angkor Wat today. Yet the monument was begun soon after Suryavarman came to the throne and was finished shortly after his death, no more than 40 years.

Virtually all of its surfaces, columns, lintels even roofs are carved. There are miles of reliefs illustrating scenes from Indian literature including unicorns, griffins, winged dragons pulling chariots as well as warriors following an elephant mounted leader and celestial dancing girls with elaborate hair styles. The gallery wall alone is decorated with almost 1,000 square meters of bas reliefs. Holes on some of the Angkor walls indicate that they may have been decorated with bronze sheets. These were highly prized in ancient times and were a prime target for robbers. While excavating Khajuraho, Alex Evans, a stone mason and sculptor, recreated a stone sculpture under 4 feet (1.2 m), this took about 60 days to carve. Roger Hopkins and Mark Lehner also conducted experiments to quarry limestone which took 12 quarrymen 22 days to quarry about 400 tons of stone. The labour force to quarry, transport, carve and install this much sandstone must have run into the thousands including many highly skilled artisans. The skill required to carve these sculptures was developed hundreds of years earlier, as demonstrated by some artifacts found that were dated to the seventh century before the Khmer came into power.

Angkor Wat today

This model of Angkor Wat is designed to give tourists an overview of the site. In the foreground is depicted the cruciform terrace which lies in front of the central structure.

The Archaeological Survey of India carried out restoration work on the temple between 1986 and 1992. Since the 1990s, Angkor Wat has seen continued conservation efforts and a massive increase in tourism. The temple is part of the Angkor World Heritage Site, established in 1992, which has provided some funding and has encouraged the Cambodian government to protect the site.The German Apsara Conservation Project (GACP) is working to protect the devatas and other bas-reliefs which decorate the temple from damage. The organisation’s survey found that around 20% of the devatas were in very poor condition, mainly because of natural erosion and deterioration of the stone but in part also due to earlier restoration efforts. Other work involves the repair of collapsed sections of the structure, and prevention of further collapse: the west facade of the upper level, for example, has been buttressed by scaffolding since 2002, while a Japanese team completed restoration of the north library of the outer enclosure in 2005. World Monuments Fund began work on the Churning of the Sea of Milk Gallery in 2008.

Angkor Wat has become a major tourist destination. In 2004 and 2005, government figures suggest that, respectively, 561,000 and 677,000 foreign visitors arrived in Siem Reap province, approximately 50% of all foreign tourists in Cambodia for both years. The influx of tourists has so far caused relatively little damage, other than some graffiti; ropes and wooden steps have been introduced to protect the bas-reliefs and floors, respectively. Tourism has also provided some additional funds for maintenance—as of 2000 approximately 28% of ticket revenues across the whole Angkor site was spent on the temples—although most work is carried out by foreign government-sponsored teams rather than by the Cambodian authorities.
