De Rudimentis Hebraicis.

One of the preeminent Christian Hebraists of his time, Johannes Reuchlin (1455-1522) mastered the Hebrew language and was a founder of the Renaissance Christian movement that sought to study Kabbalah. Alongside which, Reuchlin forcefully defended the Talmud and Jewish literature against the attacks of the apostate Jew, Johannes Pfefferkorn. De Rudimentis Hebraicis, a Hebrew grammar and lexicon, was Reuchlin’s first published book. Although it appeared two years after Pellican’s Hebrew grammar, Reuchlin’s work “is much superior and therefore considered the first important Christian work on Hebrew philology. It was influential in promoting the study of Hebrew and, as a result, study of the Hebrew Bible in the original” (M. Heller, The Sixteenth Century Hebrew Book, p. 17). Although Reuchlin wrote De Rudimentis Hebraicis in Latin, he organized it as a Hebrew book and thus it is paginated from right to left. Those who were new to Hebrew studies and instinctively opened De Rudimentis Hebraicis from the left were greeted by a Latin poem instructing them to begin from the other side. See Marx, Jewish History and Booklore, p. 324.
