The Sāsanavaṃsa (p.36 f) speaks of a Thera by this name, at whose request the Buddha went to Sudhammapura in Rāmañña to establish his religion. In a previous life Gavampati was born of an egg laid by a Nāga maiden who had relations with a sorcerer (vijjādhara). The egg was hatched and a child was born, but it died at the age of ten and was reborn at Mithilā as Gavampati. He joined the Order at the age of seven and became an Arahant. Later he visited Sudhammapura to teach his mother, and there King Sīha asked him to invite the Buddha to his country.

Gavampati Sutta.– Taught by Gavampati at Sahajāti in the Ceti country. A number of the senior monks were talking of suffering, and Gavampati tells them that he knows from the Buddha himself that whosoever understands suffering (dukkha) knows all its aspects — its nature, its arising, its cessation and the path thereto. S.v.436.
