1. Buddhadatta Thera. He lived in Uragapura in South India and wrote his works in the monastery of Bhūtamangalagāma in the Cola country, his patron being Accutavikkama.
He studied, however, at the Mahāvihāra in Anurādhapura. Tradition says (e.g., SadS., p.55) that he met Buddhaghosa.
Buddhadatta's works include the Vinaya-Vinicchaya, the Uttara-Vinicchaya, the Abhidhammāvatāra and the Rūpārūpa-Vibhāga. The Madhuratthavilāsinī and the Jinālānkāra are also sometimes ascribed to him. Svd.1195,1199; Gv.59,66,69.
For details see P.L.C.105 ff.
