Patron of Visé, Belgium (known also as Adelinus, Hadelin, Haulin); b. Aquitaine; d. Celles, Belgium, midseventh century or 690. Of noble parentage, he left home together with his teacher, St. Remaclus (d. 675), to live as a recluse in the wilderness of Cougnon. Later he lived in the Abbey of stavelot, founded by Remaclus. Assisted by him and by Pepin of Heristal, Hadalinus founded the monastery of Celles near Dinant-sur-Meuse; its 11th-century Romanesque church is extant. In 1338 the monastery was removed to Visé; it was suppressed in 1797. Hadalinus is invoked against children's ailments; in iconography his attribute is a dove.
