Sunthorn Phu ( 1786–1855) is Thailand's best-known poet. His most popular single work is the 30,000-line epic Phra Aphai Mani. His common name is from a part of his Royal given name Phra Sunthorn Vohara , combined with his birth name, Phu.
A commoner, Sunthorn Phu broke from tradition by writing in more ordinary language and about less-elevated topics than previous writers.
