Gedaliah (Eanes/Ben Yohanan) ibn Yahya ben Joseph (c. 1515 - c. 1587) (Hebrew: ? ) was a talmudist born at Imola, Italy. He studied in the yeshivah at Ferrara under Jacob Finzi and Abraham Rovigo and Israel Rovigo. In 1549 he settled in Rovigo, where he remained until 1562, in which year the burning of the Talmud took place in Italy. He then went to Codiniola, and three years later to Salonica, whence he returned in 1567 to his native town. 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.
His chief work was the Sefer Shalshelet ha-?abbalah, called also Sefer Ya?ya, 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:
The value of this work is, however, lessened considerably by the facts that the writer has included many oral narratives which he gathered partly in his home, partly in Salonica and Alexandria, and that he often lacks the ability to distinguish truth from fiction. For these reasons the book has been called "The Chain of Lies"; but J. Loeb has argued that it is more accurate than many have supposed it to be. The Shalshelet ha-?abbalah 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 O?ar ha-Sefarim (pp. 590-591).
