An arahant Thera. He was born in the family of a burgher of Sáketa and was so called because his head resembled that of a ram. When the Buddha was staying in Ańjanavana in Sáketa, Mendasira heard him preach and entered the Order, attaining arahantship in due course.
In the time of Vipassí Buddha, he lived near Mount Gotama in Himavá with a large following of ascetics. There they met the Buddha and offered him lotus flowers. Fifty one kappas ago he was a king named Januttama (Jaluttama) (Thag.78; ThagA.i.171f). He is evidently to be identified with Padumapújaka of the Apadána. Ap.i.102f.
