The Emerald Buddha (Thai: พระแก้วมรกต Phra Kaeo Morakot, or พระพุทธมหามณีรัตนปฏิมากร Phra Phuttha Maha Mani Rattana Patimakon) is an image of the meditating Gautama Buddha seated in the lotus position, made of a semi-precious green stone (jasper rather than emerald or jade), clothed in gold. and about 66 centimetres (26 in) tall. The image is considered the sacred palladium of Thailand. It is housed in the Temple of the Emerald Buddha (Wat Phra Kaew) on the grounds of the Grand Palace in Bangkok.
Historical sources indicate that the statue surfaced in northern Thailand in the Lan Na kingdom in 1434. One account of its discovery tells that lightning struck a chedi in Wat Pa Yia (Bamboo Forest Monastery, later renamed Wat Phra Kaew) in Chiang Rai, revealing a Buddha covered with stucco inside. The Buddha was then placed in the abbot's residence, who later noticed that stucco on the nose had flaked off, revealing a green interior. The abbot removed the stucco and found a Buddha figure carved from a green semi-precious stone, which became known as Phra Kaew Morakot or in English the Emerald Buddha. ("Emerald" refers to its "green colour" in Thai, not its composition.) Some art historians describe the Emerald Buddha as belonging to the Chiang Saen Style of the 15th century CE, which would mean it is of La Na origin.
The legend reports that King Sam Fang Kaen of Lan Na wanted it in his capital, Chiang Mai, but the elephant carrying it insisted, on three separate occasions, on going instead to Lampang. This was taken as a divine sign, and the Emerald Buddha stayed in Lampang in a specially-built temple (now Wat Phra Kaeo Don Tao) for the next 32 years. In 1468, it was moved to Chiang Mai by King Tilokaraj, where it was kept in a niche in a large stupa called Chedi Luang.
The Emerald Buddha remained in Chiang Mai until 1552, when it was taken to Luang Prabang, then the capital of the Lao kingdom of Lan Xang. Some years earlier, the crown prince of Lan Xang, Setthathirath, had been invited to occupy the vacant throne of Lan Na as his mother was the daughter of the king of Chiang Mai who had died without an heir. However, Prince Setthathirath also became king of Lan Xang when his father, Photisarath, died. He returned home, taking the revered Buddha figure with him.
In 1564, King Setthathirath moved it to Vientiane, which he had made his new capital due to Burmese attacks and where the Buddha image was housed in Haw Phra Kaew. The Buddha image would stay in Vientiane for the next 214 years.
In 1779, the Siamese General Chao Phraya Chakri put down an insurrection, captured Vientiane and took the Emerald Buddha to Siam. It was installed in a shrine close to Wat Arun in Thonburi, the new capital of Siam. Chao Phra Chakri then seized the throne for himself and founded the Chakri Dynasty of the Rattanakosin Kingdom, where he would later be titled King Rama I. He shifted his capital across Chao Phraya river to its present location in Bangkok, and constructed the new Grand Palace including Wat Phra Kaew within its compound. Wat Phra Kaew was consecrated in 1784, and the Emerald Buddha was moved with great pomp and pageantry to its current home in the ubosot of the Wat Phra Kaew temple complex on 22 March 1784.
The Buddha image is made of a semi-precious green stone, described variously as jade or jasper rather than emerald, as "emerald" here refers to its colour rather than the stone. The image has not been analyzed to determine its exact composition or origin.
The figure is 48 centimetres (19 in) wide at the lap, and 66 centimetres (26 in) high. The Buddha is in a seated position, with the right leg resting on the left one, a style that suggest it might have been carved in the late Chiang Saen or Chiang Mai school, not much earlier than the fifteenth century CE. However, the Meditation attitude of the statue was not popular in Thailand but looks very much like some of the Buddha images of southern India and Sri Lanka, which led some to suggest an origin in India or Sri Lanka.
The Emerald Buddha is adorned with three different sets of gold seasonal decorations: two were made by Rama I, one for the summer and one for the rainy season, and a third made by Rama III for the winter or cool season. In 1996 to celebrate the Golden Jubilee of King Bhumibol Adulyadej, the Bureau of the Royal Household commissioned a replica set of the seasonal decorations to be made in all the same materials. This new set was funded entirely by donations. The original set, which were made over 200 years ago, were retired and are on display at the Museum of the Emerald Buddha Temple in the Middle court of the Grand Palace.
The decorations are changed by the King of Thailand, or a senior member of the royal family in his stead, in a ceremony at the changing of the seasons – in the 1st Waning of lunar months 4, 8 and 12 (around March, August and November).
The sets of gold clothing not in use at any given time are kept on display in the nearby Pavilion of Regalia, Royal Decorations, and Thai Coins on the grounds of the Grand Palace, where the public may view them.
Early in the Bangkok period, the Emerald Buddha was occasionally taken out and paraded through the streets to relieve the city and countryside of various calamities (such as plague and cholera). This practice was discontinued during King Rama IV's reign as it was feared that the image could be damaged during the procession and the king's belief that; "Diseases are caused by germs, not by evil spirits or the displeasure of the Buddha".
The Emerald Buddha also marks the changing of the seasons in Thailand, with the king presiding over seasonal ceremonies. In a ritual held at the temple three times a year, the decoration of the deity is changed at the start of each of the three seasons. The astrological dates for the ritual ceremonies, at the changing of the seasons, followed are in the first waning moon of the lunar calendar, months 4, 8 and 12 (around March, July, and November). Rama I initiated this ritual for the hot season and the rainy season; Rama III introduced the ritual for the winter season. The decoration which adorn the image, represent those of monks and the king, depending on the season, an indication of its symbolic role "as Buddha and the King", which role is also enjoined on the king who formally dresses the Emerald Buddha himself. The costume change ritual is performed by the king who is the most elevated master of ceremonies for all Buddhist rites. During the ceremony, the king first climbs up to the pedestal, cleans the image by wiping away any dust with a wet cloth, and changes the gold headress of the Emerald Buddha. The king then worships nearby while an attendant performs the elaborate ritual of changing the rest of the decorative garments. The king also sprays holy water, which is mixed with the water rinsed from the wet cloth used to wipe the dust of the image, upon his subjects waiting outside the ordination hall. Previously this was a privilege afforded only to the princes and officials who were attending the ceremony (uposatha) inside the ubosot.
Ceremonies are also performed at the Emerald Buddha temple at other occasions such as Chakri Day (6 April 1782), a national holiday to honour the founding of the Chakri dynasty. The king and queen, an entourage of the royal family, as well as the prime minister, officials of the Ministry of Defence and other government departments, offer prayers at the temple.
The legend of the Emerald Buddha is related in number of sources such as Jinakalamali, Amarakatabuddharupanidana, and in particular Ratanabimbavamsa or The Chronicle of the Emerald Buddha written in Pali by Brahmarājapañña in the 15th century. The story is a mix of fact and fables with some variations to the story. According to the legend, the Emerald Buddha was created in 43 BCE by a saint named Nagasena in the city of Pataliputra (today's Patna), India. Nagasena allegedly had the help of Hindu god Vishnu and the demigod Indra, 500 years after Buddha attained Nirvana. He was said to have predicted:
