Rama II rewrote much of the great literature from the reign of Rama I in a modern style. He is credited with writing a popular version of the Thai folk tale Ramakien and wrote a number of dance dramas such as Sang Thong. The king was an accomplished musician, playing and composing for the fiddle and introducing new instrumental techniques. He was also a sculptor and is said to have sculpted the face of the Niramitr Buddha in Wat Arun. Because of his artistic achievements, Rama II's birthday is now celebrated as National Artists' Day (Wan Sinlapin Haeng Chat), held in honor of artists who have contributed to the cultural heritage of the kingdom.
