Yama Zatdaw (Burmese: ရာမဇာတ်တော်, pronounced [jàma̰ zaʔ tɔ̀]), unofficially Myanmar's national epic, is the Burmese version of the Ramayana and Dasaratha Jataka. There are nine known pieces of the Yama Zatdaw in Myanmar. The Burmese name for the story itself is Yamayana, while zatdaw refers to the acted play or being part of jataka tales of Theravada Buddhism.
Depending on the methods of counting, as many as three hundred versions of the Indian Hindu epic poem, the Ramayana, are known to exist. The oldest version is generally recognized to be the Sanskrit version attributed to sage Narada, the Mula Ramayana. Narada passed on the knowledge to Valmiki, who authored Valmiki Ramayana, the present oldest available version of Ramayana.
The Ramayana has spread to many Asian countries outside of India, including Burma, Indonesia, Cambodia, Laos, Philippines, Sri Lanka, Nepal, Thailand, Singapore, Malaysia, Japan, Mongolia, Vietnam and China. The original Valmiki version has been adapted or translated into various regional languages, which have often been marked more or less by plot twists and thematic adaptations. Some of the important adaptations of the classic tale include the 12th-century Tamil language Ramavataram, 12th-century Kannada Ramachandra Charitapurana or Pampa Ramayana by Nagachandra, 13th-century Telugu language Sri Ranganatha Ramayanam, 14th or 15th-century Assamese Saptakanda Ramayana, 15th-century Bengali Krittivasi Ramayana, 16th-century Awadhi Ramcharitmanas, 17th-century Malayalam language Adhyathmaramayanam Kilippattu, the Khmer Reamker, the Old Javanese Kakawin Ramayana, and the Thai Ramakien, the Lao Phra Lak Phra Lam, and the Burmese Yama Zatdaw.
