WAT SAO CHINGCHA

Playing on the swing
The important ceremony of Tri Yampawai Tripawai, popularly known as Lo Chingcha (โล้ชิงช้า) ("playing on the swing" was one of the most interesting of all Siamese State Ceremonies. None of the seventeenth century European writers mentions this ceremony, except for Van Vliet, which was practised in the Ayutthaya period. [3]
The rite was performed to pay Shiva homage and commemorate the god’s annual visit to the earth. Once a year, the god Shiva comes down to visit this world and stays here for ten days. He used to arrive on the seventh day of the waxing moon in the first month and depart on the first day of the waning moon. Thus, the Swinging Festival was performed in the first lunar month, but this was changed in the Rattanakosin period to the second month. (3) It was not only an important State Ceremony in the former capitals of Ayutthaya and Sukhothai but was practised in the other chief cities of the realm in ancient times. [3]
Though Jeremias Van Vliet wrote in his "Short History of the Kings of Siam” in 1640 CE that the first swing was brought to Ayutthaya by two Brahmin priests during the reign of King Ramathibodi II (reign 1491-1529 CE), the royal ceremony was likely already known since the Sukhothai period and still performed during the Rattanakosin era until the 1930s. [2]
"The king of Ramaradt therefore sent two learned brahman priests with a letter in a friendly tone to the king of Siam asking that His Majesty forget all that had gone before and accept him as a brother. He also instructed the brahmans that they should make the game of schoppen or scbongelen known in Siam and to establish it there."’ The Siamese king accepted the brahmans, the letter, and the proffered peace, and sent a letter in reply establishing a friendship between both kings which has been maintained to the present day, renewed every two to three years by means of letters engraved in gold. Since then, various brahmans have come to Siam from many places, especially from Ramaradt, and have continued to be held in great esteem among the kings, princes, the royal family, and the community. At that time the Moorish traders from the Coromandel Coast came with their cloth, which practice continues to the present day. Scboppen or schongelen is still found today, because there are special places set out for playing it. There are special feast days held yearly which go on from one day to the next for a long time." [4]
Quaritch Wales concluded that the "swinging" was originally a solar ceremony. He stated that there were two ceremonies of swinging known in India, and both of these were of solar origin. His statement that the Siamese "Lo Ching Cha", originally a sun ceremony, was based on the following characteristics: The "swinging" occurs at the time of the winter solstice It is performed from east to west, in the direction of the course of the sun. The swing-posts are oriented out of the plane of the transverse axis of the plaza in the centre of which they are situated so that the swinging should be performed precisely from east to west, and finally, the circular dances which follow the swinging probably symbolise the revolution of the sun and its rebirth on the occasion of its return to the northern hemisphere. The ceremony was originally a rite of imitative magic, intended to coerce the god Surya into fulfilling his functions. It was the to and fro motion of the swing which impressed the ancients, symbolising the path of the sun. Quaritch wrote:

"The most noticeable and perhaps the earliest change that took place in the subsequent history of this ceremony was the substitution of Siva for Surya….Surya was a Vedic god who sank to comparatively low estate in Brahmanic times, and, with the growth of Saivism, the original meaning of the ceremony was lost, and the Great God naturally came to usurp the place of the forgotten sun-god. The Swinging may have come to be regarded as symbolizing the functions of Siva as Destroyer and Reproducer, and thus it would have retained its magical significance although now brought more closely into connection with agriculture as one of the many Hindu harvest festivals."

According to Siamese notions, Siva is a jovial god who likes to be amused, so the swinging and the acrobatic feats accompanying the procession are devised for his entertainment. The connection between swinging and harvest probably came into being before the arrival of the ceremony in Siam, i.e. it was probably never a purely solar ceremony in Siam. [5]
During the Ayutthaya period, the King remained in his palace on the occasion of the swinging ceremony. The King appointed the Minister of Agriculture to impersonate Shiva. During the three days that the festival lasted, this noble used to have almost unlimited powers and rights over certain State revenues. He was, in fact, a "temporary king" or "temporary god", the two terms being almost synonymous in Siam. The fact that the Minister of Agriculture performed the role of Shiva points to a connection with a harvest festival. The Swinging Festival was made to coincide with the new year of the Brahmans. [6]
Wat Sao Chingcha must have been approximately located in geographical coordinates: 14° 21' 10.48" N, 100° 34' 12.14" E.

(1) The remains of the original Bangkok swing are now in the Bangkok National Museum, while the renovated swing was installed in front of Wat Suthat in 1920 CE. [2](2) Quaritch Wales wrote in 1930 CE that he was informed on high authority that the Supreme Council of State considered the question of abolition. He noticed little interest in the "swinging, which meant absolutely nothing to the modern Siamese." [1](3) It was not difficult to postpone the date of his arrival until the second month. For the Brahmans, like the Pope, hold that they keep the keys of Heaven and, of course, Shiva could not come down till they had opened the door for him. [3].
