Shin Raṭṭhasāra

Shin Raṭṭhasāra (Burmese: ရှင်မဟာရဋ္ဌသာရ; 1468–1529 (1530) was a Buddhist monk and prominent classical poet during the Ava Kingdom, known for his pyo poetry. His 1523 Kogan Pyo (ကိုးခန့်ပျို့) based on the Hatthipāla Jātaka, is among the most widely known pyo in modern-day Myanmar, and is taught in Burmese schools. His Buridat Pyo (ဘူရိဒတ်ပျို့; based on the Bhūridatta Jātaka) is also considered an exemplar of the medieval literary style, is considered a masterpiece of Burmese classical poetry. Raṭṭhasāra also composed metrical versions of other Jataka tales, including the Saṃvarajātaka, besides a number of other poems.

Despite his poetic contributions, Burmese chroniclers excluded him from the succession of elders (thera), because he not only wrote verse, but also recited and instructed pupils in the art of recitation, which was considered a transgression of the Vinaya, specifically the rules governing singing and dancing.
