Jacob ben David ben Yom Tov
Medieval Spanish astronomer, active 14th century
Jacob ben David ben Yom Tov (also Yomtob or Jomtob or Bonjourn or Bonet), also known as ha-Poel (or Fu'al), was a Catalan Jewish astronomer and astrologer. He lived, probably at Perpignan, in southern France 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 (MS Casanatense 3155).
This brief starts where responsible research should: with the source description of “Jacob ben David ben Yom Tov” as medieval Spanish astronomer, active 14th century. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as medieval Spanish astronomer, active 14th century. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Feb 16, 2025. The linked authority identifier is Q6119519. VIAF identifies the subject as 41248209. The Library of Congress control number is n2005042401. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1361 and 2072.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
