Jacob ben David ben Yomtob

From Wikipedia, the free encyclopedia

Jacob ben David ben Yomtob[1] was a Catalan Jewish astronomer. He lived, probably at Perpignan, in the fourteenth century.

He was the author of astronomical tables prepared at Perpignan in 1361. These tables, still extant in manuscript (Bibliothèque Nationale, Paris, MS. No. 10,901; Adolf Neubauer, "Cat. Bodl. Hebr. MSS." No. 2072, 2), enjoyed a great reputation. They were translated into Latin in the fifteenth century, and were the subject of many Hebrew commentaries, among which was one written by Joseph ben Saul Ḳimḥi (Vatican MSS. Nos. i., v., 1, 7). Many manuscripts of these tables were retranslated from Latin into Hebrew.

His father is given as David ben Yom-Ṭob ibn Bilia/David Bongoron.
