one of the most celebrated Jewish Cabalists, was born at Frankfort-on-the- Main in the latter half of the 16th century. The only work of Hirz which was printed, עֵמֶק הִמֶּלֶךְ, or Valley of the King (Amst. 1848, fol.), is a complete expose of the Cabala. The vast research which he made for the preparation of this work makes it indispensable for inquirers into the Cabalistic system. He died, Furst says, in Palestine, but the date is not certainly known. — Furst, Biblioth. Judaica, 1, 401; Hoefer, Nouv. Biog. Gé neralé, 24, 800.
