Through subsequent kings Lan Xang would repair the damage of the war with Đại Việt, which led to a blossoming of culture and trade. King Visoun (1500–1520) was a major patron of the arts and during his reign the classical literature of Lan Xang was first written. The Theravada Buddhist monks and monasteries became centers of learning and the sangha grew in both cultural and political power. The "Nithan Khun Borom" (Story of Khun Borom) first appeared in written form, along with several transcriptions of the Jataka Tales which recall previous lives of the Buddha. The Tripitaka was transcribed from Pali to Lao, and the Lao version of the Ramayana or "Pra Lak Pra Lam" was also written.
