CANISIUS, or DE HONDT, HENRY, a native of Nimeguen, and one of the most learned men of his time, was professor of canon law at Ingolstadt. His principal works are, Summa Juris Canonici and Antiquæ Lectiones. This latter very valuable work was reprinted, with some curious and useful remarks, under the title of Thesaurus Monumentorum Ecclesiasticorum et Historicorum, &c., Amsterdam, 1725, in seven parts, usually bound in 4 vols. folio. Canisius died in 1610.
