Dominicus Lampsonius (Latinised form of Dominique Lampsone) (1532, in Bruges – 1599, in Liège) was a Flemish humanist, poet and painter. A secretary to various Prince-Bishops of Liège, he maintained an extensive correspondence with humanists and artists at home and abroad. HIs writings on Netherlandish artists formed an important contribution to the formation of the so-called Netherlandish canon.
Lampsonius studied arts and sciences at the University of Leuven. In 1554 he went to England to serve as secretary to Reginald Pole, a prominent humanist and Roman Catholic Cardinal. After Pole's death in 1558, he traveled to Liège where he was secretary to the successive Prince-Bishops (Robert of Berghes, Gerard of Grœsbeek, and Ernest of Bavaria). He thus regularly collaborated with Laevinus Torrentius who was the vicar of the Prince-Bishops until 1586 after which he became Bishop of Antwerp.
Lampsonius was for a while the teacher of Otto van Veen, a painter and humanist who would later be one of the masters of Peter Paul Rubens. He became friends and engaged in intensive correspondence with some of the leading humanists of his time such as Justus Lipsius, Janus Dousa, Johannes Livineius and Petrus Oranus.
