the effects of light and the colours in a very subtle manner. Pontius worked as one of the principal engravers for Rubens' workshop. Pontius also worked after the work of pupils or imitators of Rubens. He can be regarded as one of the principal engravers of van Dyck's work. Altogether Pontius produced 42 plates after Rubens. As several of these works were portraits of the rulers of the Spanish Netherlands such as the king and queen of Spain and the governors and ministers of the Spanish Netherlands, Pontius can be seen as the official portrait engraver. An example is the Portrait of Gaspar de Gusman, Count of Olivares, which Pontius made in 1626 after a design by Rubens. This was one of his first important portrait commissions and the success of the print led to many more official commissions. In his portraits Pontius conveyed the figures and their expressions in an attractive and faultless manner. This quality of his work made him one of the most sought after engravers for the various publication projects of the prominent portrait painters active in Flanders at the time. He made many of the portrait engravings that were published in van Dyck's Iconography (Antwerp, c. 1632–44), Johannes Meyssens' Images de divers hommes, Cornelis de Bie's Het Gulden Cabinet (Antwerp, 1661) and Anselm van Hulle's Icones legatorum (Antwerp, 1648).
