In this genre he was immensely prolific and also immensely successful—Houbraken says he left his daughter a dowry of 20,000 guilders. He had many imitators, including his brother Peter (1623–82), and his great popularity continued throughout the 18th century, when he was a favourite with princely collectors and engravings after his work had wide circulation. Subsequently he has perhaps been underrated, for although his work generally follows a successful formula, he maintained high standards: his draughtsmanship is elegant, his composition sure, his colouring delicate, and his touch lively.
