Boetius à Bolswert was a renowned copper-plate engraving engraver of Friesland origin. In his time the paintings of Peter Paul Rubens called forth new endeavours by engravers to imitate or reproduce the breadth, density of mass and dynamic illumination of those works. Boetius Bolswert was an important figure in this movement, not least because he was the elder brother and instructor of the engraver Schelte à Bolswert, whose reproductions of Rubens's landscapes were most highly esteemed in their own right.
