Originally published in two volumes, this edition of the Arabic translation of the Pentateuch stands as one of Lagarde’s lasting contributions to biblical scholarship. Critical editions make frequent reference to this work. Included are two translations of Genesis into Arabic, along with a single version of the remaining pentateuchal books, also in Arabic. The first translation of Genesis represents the tradition of the Paris Polyglot, translated directly from the Hebrew, while the second is a cantena text from the Syriac tradition, representing two-thirds of Genesis. Lagarde’s study provides a valuable text-critical tool and easy access to the Arabic versions of the material.
