The Eulogy of King Prasat Thong, probably composed early in the reign of King Narai is a major example of the Thai tradition of royal panegyrics. It states that King Prasat Thong is a bodhisatta, invited by Indra to be reborn as the king of Ayutthaya, and destined to become the tenth in a sequence of ten future Buddhas beginning with Metteyya. It recounts the major events of the reign including religious constructions, amending the calendar, almsgivings, and festivals.
