Son of Dhātusena by a morganatic marriage. He slew his father and became king of Sri Lanka as Kassapa I (478-96 A.C.). Fearing the revenge of his brother Moggallāna, he erected the fortress at Sīhagiri and dwelt there. Later, repenting of his patricide, he did many meritorious deeds by way of amends (for details see Cv.xxxix.8 ff), chief of which was the restoration of the Issarasamaṇārāma, to which he added buildings named after his daughters, Bodhī and Uppalavaṇṇā. In a fight with his brother’s forces his army fled in disorder, and Kassapa cut his throat with a dagger. Cv.xxxviii.80 ff; xxxix.1 ff.
