Jinacarita

Jinacarita, “the career of the Conqueror” — the life of the Buddha from the time of Dīpaṅkara onward, in 449 verses of highly ornate metre, with fifteen more at the end setting out the author's wishes for his future lives.

He names himself: the Thera Medhaṃkara, living in a monastery built by a King Vijayabāhu; in the colophon to his Payogasiddhi he calls himself a pupil of Sumaṅgala of the Jambuddoṇi monastery — which is how he is kept apart from the Sumaṅgala who taught the subcommentator Sāriputta. The Pali catalogue agrees: jinacaritaṃ nāma pakaraṇaṃ attano matiyā medhaṅkarācariyena kataṃ.

Which Vijayabāhu is the open question, and it does not matter as much as it looks. Duroiselle takes it as Vijayabāhu II (1186–1187 CE), Malalasekera as Vijayabāhu III (1232–1236 CE); on either reading Medhaṃkara belongs to the 1200s CE.
