Sanderus was born "Antoon Sanders", but like all writers and scholars of his time he Latinized his name. Having become master of philosophy at the
University of Douai in 1609, he studied theology for some years under
Johannes Malderus (Jan van Malderen) at the
University of Leuven, and
Willem Hessels van Est (Estius) at Douai, and was ordained
priest at
Ghent. For some years he was engaged in parochial duties, and combated the
Anabaptist movement in Flanders with great zeal and success. In 1625, he became secretary and
almoner of Cardinal
Alfonso de la Cueva, later becoming
canon and
scholaster of
St Martin's Cathedral, Ypres. Publication of the first volume of his sumptuously illustrated
Flandria illustrata (1641) nearly bankrupted him, and he was rescued from ruination by an award of 1,000 florins through the
Lille Chamber of Accounts. Further such subventions in support of his work followed in 1645, 1651, 1655 and 1662. In 1654, he was appointed
penitentiary at
Ypres. After three years, however, he resigned this office to devote himself entirely to scientific, and especially to historical studies. He soon found himself compelled to claim the hospitality of the
Benedictine Abbey of Afflighem, since he had reduced himself to absolute poverty by the publication of numerous works. ==Writings==
