The fourteenth book of the Khuddaka Nikáya (DA.i.17).
The Dígha-bhánakas excluded it from the canon, but it was accepted by the Majjhima-bhánakas (DA.i.17).
It contains, in verse, the lives of the twenty five Buddhas, of whom Gotama was the last. The name of the Bodhisatta under each Buddha is also given. The last chapter deals with the distribution of Gotama's relics.
It is said (Bu.i.74) that the Buddhavamsa was preached, at Sáriputta's request, at the Nigrodháráma in Kapilavatthu, after the Buddha had performed the miracle of the Ratanacankama. The Commentary on the Buddhavamsa is known as the Madhurattha-vilásiní (q.v.).
The Gandhavamsa (p.61) speaks of a Buddhavamsa written by an author named Kassapa. This is probably not the same work. Mention is also made (Gv.60) of a Tíká to the Buddhavamsa, Paramatthadípáni by name.
