Together with the brothers Ambrosius Francken I and Frans Francken I, he ranks among the most important painters of altarpieces in Antwerp during the 1590s. Due, in part, to the Counter-Reformation, there was a renewed demand for altarpieces to replace those lost during iconoclastic riots in 1566 or the reformist movement of 1581.
Marten de Vos was also a prolific draughtsman, especially during the first half of the 1580s, when the Calvinists were in power in Antwerp. During this period he provided numerous designs for print publishers. A total of some 1600 prints were produced after designs by de Vos. De Vos's drawings have been praised for their lively, industrious and generally positive character, frequently with romantic Italianate landscapes in the background. His obvious proficiency is counterbalanced, however, by a degree of routine formularization. More on Marten de Vos
