Gedaliah ibn Yahya ben Joseph

Born in Imola, Italy, the son of Joseph ibn Yahya ben Solomon and Abigail. In his early years he studied in Ferrara under Abraham Rovigo, later settling down in Rovigo, where he remained until 1562 when the burning of the Talmud took place in Italy. Following this he briefly lived in Salonica, moving back to Imola in 1567. He was later expelled with other Jews by Pope Pius V, and suffering a loss of 10,000 gold pieces, he went to Pesaro, and thence to Ferrara, where he remained till 1575. During the ensuing eight years he led a wandering life, and finally settled in Alexandria, which is probably where he died in 1587. Ibn Yayha's chief work was the Sefer Shalshelet ha-Ḳabbalah, called also Sefer Yaḥya, on which he labored for more than forty years. This work is not without defects, having suffered either by reason of the author's itinerant mode of life or through faulty copying of the original manuscript. Its contents are as follows:[1]

• History and genealogy of the Jews from the time of Moses until that of Moses Norzi (1587)
• Account of the heavenly bodies, Creation, the soul, magic, and evil spirits
• History of the peoples among which the Jews have dwelt, and a description of the unhappy fate of the author's coreligionists up to his time.

The Shalshelet ha-Ḳabbalah was published at Venice, 1587; Cracow, 1596; Amsterdam, 1697; Zolkiev, 1802, 1804; Polonnoye, 1814; and Lemberg, 1862.

Gedaliah was the alleged author of twenty-one other works, which he enumerates at the end of his Shalshelet and which are mentioned also in Benjacob's Oẓar ha-Sefarim.
