Testament of Ba

The Testament of Ba or the Chronicle of Ba(Tibetan དབའ་བཞེད or སྦ་བཞེད; Wylie transliteration: dba' bzhed or sba bzhed) is a Tibetan chronicle written in 8th century Classical Tibetan documenting the establishment of Tibetan Buddhism and the Vajrayana, Samye Monastery and the Samye Debate, and notable events and people in Tibet's history. Written during the Tibetan Empire period, it covers the reigns of kings Songsten Gampo, Trisong Detsen (r. 755–797/804), and the years after Rapalchen's reign. The monk Ba Salnang (Tibetan སྦ་གསལ་སྣང; Wylie transliteration: sba gsal snang) of the Ba Family was the main recorder of the Chronicle who used other scribes and members of the kings' courts.

In 2008, early versions of the text were said to have been discovered in London, where two manuscript fragments possibly dating to the 9th or 10th centuries are held by the British Library.
