JOSIPHIAH (Jehosiphia) THE PROSELYTE (early 12th century), French liturgical poet. Josiphiah is quoted by *Jacob ha-Levi of Marvège and is also mentioned in Sefer ha-Gan, and by *Judah b. Eliezer (1313) and Moses *Rieti (15th century). Of the known eight poems which bear Josiphiah's signature, only three have been published, among them an introduction to Illu Finu, translated into German by S. Heller (Die echten hebraeischen Melodien (19083)) on the basis of S.D. Luzzatto's edition in Tal Orot (1881), 34, no. 43.
