The depicted icon is inspired by a Thai letter “ส” (So Suea) derived from the name Sdok Kok Thom (meaning “a huge stone temple surrounded by a mess of reeds) mentioned in the Sdok Kok Thom Inscription No.2 that lasts from Ancient Khmer Kingdom. The inscription was built in 1052 during the Reign of King Udyaditya Varman II of Ancient Khmer and belongs to the great significance of Southeast Asian Historical Studies since the lineage of Brahmins and Ancient Khmer kings are completely recorded there; this information can be traced back to 200 years. Today the Sdok Kok Thom Inscription No.2 is displayed in Prachinburi National Museum. Its information, along with other related accounts, is available in the information centre of Sdok Kok Thom Historical Park.
