Bachya ben Asher ben Chlava. Rabenu Bechaye al ha-Torah. Koretz, Abraham ben Isaac and Elijah ben Jacob Segal, 1799

A Kabbalistic commentary on the Torah by the 13th-century 'divine kabbalist' Bachya ben Asher of Saragossa, begun in 1291, and probably with knowledge of the Zohar, which was then being circulated. First printed in Venice in 1492, Bachya's clarity of style made this commentary very popular and it went through many editions. Although Bachya generally did not name his kabbalistic sources explicitly, he demonstrably often consulted the works of his contemporary Gikatilla.
