Two of Christophe Plantin’s sons-in-law. On the left, Jan Moretus (1543-1610); on the right, Franciscus Raphelengius (1539-97). Moretus and Raphelengius ran the Antwerp and Leiden businesses, respectively. The Moretus detail is based on a painting by Peter Paul Rubens, ca. 1613-16, or some years after the death of Moretus.
