BALBUS, Johannes (d. 1298). Catholicon. Nuremberg: Anton Koberger, 21 August 1486.

Second Koberger edition of the most important Latin dictionary and encyclopedic compendium of the Middle Ages. Universal in scope, the Catholicon draws on sources both ancient and medieval, including Isidore of Seville, Priscian, and Donatus and covers grammar, rhetoric and pronunciation as well as definitions of words; its alphabetical arrangement, now taken for granted for a work of reference, was far from standard at the time of its composition.
