Gregentius, Saint bishop of Tephae, in Arabia, was born at Soplian, "on the frontier of Asia," but other authorities say, at Milan, on December 19 (his festal day); He went to Alexandria, where he embraced the life of an anchorite, and' was sent to take charge of the Homerites; He propagated Christianity among the idolaters of Yemen, and is said to have died in 552. There is a book extant, giving some details of part of his life, entitled: Τοῦ ἐν ἁγίοις Πατρὸς ἠμῶν Γρηγηντίου ἀρχιεπισχόπου γενομένον Τεφρῶν, etc. (Migne, Patrol. Graec. 86:5). See Hoefer, Nouv.
