Buddha altar U Thong style

Uthong (1314–1369) was the first king of the kingdom Ayutthaya (now part of Thailand), reigning from 1351 to 1369. He was known as Prince U Thong before he ascended to the throne on March 4, 1351.
The U Thong style, one of the canonical styles for Buddha icons developed in Thailand (Siam) in the southern capital of Ayutthaya, beginning in the 14th century. To retain the greatest spiritual potency, Buddha icons in Thai temples had to resemble as closely as possible an original prototype that tradition erroneously believed had been made during the lifetime of the Buddha.
