This interesting and varied exploration of early modern Greek and Hebrew teaching grew out of a 2017 conference to mark the five hundredth anniversary of the founding of Leuven’s Collegium Trilingue, an institution offering free instruction in Latin, Greek and Hebrew from 1517 until its suppression in 1797. While the Collegium Trilingue was clearly special both in being the brainchild of Erasmus and in being among the first Western European institutions to offer systematic instruction in Greek and/or Hebrew, the learning of these languages rapidly became more widespread over the sixteenth century, as did the publication of books in and about them. This collection of essays considers that trend in general and picks out some noteworthy individual examples.
