1. Dhātusena.-A householder of Nandivāpigāma, father of Dāthānāma. Cv.xxxviii.14.
2. Dhātusena.-King of Ceylon (460-78 A.C.). He was the son of Dāthānāma and brother of Silātissabodhi. He seems to have had another brother, Kumārasena (q.v.). Dhātusena belonged to the Morjyavamsa. He became a monk under his uncle, the incumbent of Dīghasandasenāpati-parivena, and remained with him till preparations for his campaign were made. Then he returned to the lay life, killed the Pāndyan, Tiritara, then reigning at Anurādhapura, and became king. His chief work was the construction of the Kālavāpi, which he carried out by damming the Gonanadī. He built eighteen vihāras and eighteen tanks. He showed great favour to the monks and did many works of piety. The Ambatthala-vihāra he gave to the Dhammarucikas.
He had two sons - Moggallāna and Kassapa. Kassapa rebelled against his father at the instigation of his brother-in-law-who had been punished for ill-treating the king's daughter - and seized Dhātusena in the hope of securing his treasure. The king asked to be taken to Kālavāpi, saw the Thera who had been his teacher, and announced that his whole treasure was the Kālavāpi. Kassapa then had him buried alive.
Among Dhātusena's gifts is mentioned that of one thousand gold pieces spent by him for an interpretation (?) of the Dīpavamsa (dīpetum Dīpavamsam). Cv.xxxviii.14f, 30ff.
