OBADIAH, THE NORMAN PROSELYTE (third quarter 11th century–first half 12th century). Catholic priest who converted to Judaism. Obadiah later wrote religious works and became a prominent figure in the Near Eastern Jewish communities. He was born in Oppido Lucano (Italy) as Johannes, the son of a Norman aristocrat named Dreux (Dreu, Drogo, Droco); his twin Roger was destined for knighthood. As a youth he was influenced by the conversion of Andreas, archbishop of Bari, who adopted Judaism in Constantinople and subsequently departed for Egypt.

CHRONOLOGICAL ANNOTATED BIBLIOGRAPHY:
The record of the discovery of Obadiah's existence and works dates from the early 20th century. The beginning of the letter by Baruch b. Isaac was published by S.A. Wertheimer in Ginzei Yerushalayim (2 (1901), 16a–17a) and the first page of Obadiah's diary was printed by E.N. Adler (REJ, 69 (1919), 129–34). Two fragments discovered in Cambridge and a page of a prayer book written by Obadiah, found in Cincinnati, were presented by J. Mann (REJ, 89 (1930), 245–59). S.D. Goitein published another fragment containing Obadiah's original name, Johannes (JJS, 4 (1953), 74–84) and A. Scheiber, a piece of Obadiah's diary (KS, 30 (1954/55), 93–98). A piyyut with musical notation in Obadiah's handwriting is included in the Adler collection. Its discovery was made independently by A. Scheiber (Tarbiz, 34 (1964/65), 366–71) and by N. Golb (JR, 45 (1965), 153–6). The continuation of the booklet of music notes was published by N. Allony in Sinai (57 (1965), nos. 1–2, 43–55). A. Scheiber also published a piyyut, an acrostic of the name Obadiah (Tarbiz, 35 (1965/66), 269–73), and the original of a Hebrew fragment (HUCA, 39 (1968), 168–75, Ger.).
