Ibn-Jachja, Gedalja a Jewish historian, was born at Imola about 1515. He deserves mention here on account of his work Shalsheleth Hakkabala, or Chain of Tradition (Zolkiew, 1804). It is a history of the Jews, and is divided into three parts, of which part first only is the Shalsheleth, or literary chronicle of rabbinism; the other parts treat not only of history proper, but include also natural history, pneumatology, and economics. He died about 1587. — Carmoly, Die Jachjiden, p. 33 sq.; Gratz, Gesch. der Juden, 9, 435; Etheridge, Introd. to Heb. Lit. p. 452; Furst, Biblioth. Jud. 2, 3.
