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.
The first chapter tells how Gautama Buddha, to demonstrate his supernormal knowledge, creates a jewelled walkway in the sky. In seeing this display, Sāriputta asks the Buddha:
In response, the Buddha relays the remainder of the Buddhavamsa.
In the second chapter Gautama tells how in a distant past life as Sumedha, he received a prediction from the then Dīpankara Buddha that "In the next era you will become a buddha named Śākyamuni.", and thought out the ten perfections he would need to practice.
Chapters 3 through 26 are accounts of the twenty-four historical Buddhas who preceded Gautama Buddha, and the acts of merit that Gautama Buddha performed towards them in his previous lives.
