Rodolphus Agricola was a pre-Erasmian humanist of the Northern Low Countries, famous for his knowledge of Latin and Greek. He was an educator, musician, builder of church organs, a poet in Latin and the vernacular, a diplomat, a boxer and a Hebrew scholar towards the end of his life. Today, he is best known as the author of De inventione dialectica, the father of Northern European humanism and as a zealous anti-scholastic in the late fifteenth century.
