[1] The earliest surviving poetic literature found in the Burmese language dates from between 1450 and 1550,[2] and is largely in the form of pyo.
[2] Poets employed many devices to overcome the four-syllable requirements, including use of repetition and rhyme.
[3] Pyo were largely composed by Buddhist monks who worked in service of Burmese court.
[3] Shin Maha Silavamsa, wrote two pyo based on Buddha's previous rebirth as Sumedha Buddha, while Shin Aggasamadhi wrote three pyo based on the Nemi Jātaka.
[1] Shin Silavamsa's Hsudaungkhan Pyo (ဆုတောင်းခန့်ပျို့; based on the Sumedhapandita Jātaka) and Shin Raṭṭhasāra's Buridat Pyo (ဘူရိဒတ်ပျို့; based on the Bhūridatta Jātaka) are considered exemplars of the medieval literary style, and are treated as masterpieces of Burmese classical poetry.
