What is "buddhavamsa"

The Buddhavamsa (also known as the Chronicle of Buddhas) is a hagiographical Buddhist text which describes the life of Gautama Buddha and of the twenty-four previous Buddhas who had prophesied his attainment of Buddhahood. It is the fourteenth book of the Khuddaka Nikāya, which in turn is the fifth and last division of the Sutta Piṭaka. The Sutta Piṭaka is one of three pitakas (main sections) which together constitute the Tripiṭaka, or Pāli Canon of Theravāda Buddhism.

Along with the Apadāna and the Cariyāpiṭaka, the Buddhavamsa is considered by most scholars to have been written during the 1st and 2nd century BCE, and is therefore a late addition to the Pāli Canon.
