a Flemish Baroque painter, architect, engineer, astronomer, and art dealer who was part of the inner circle of Peter Paul Rubens. It is believed that he became a pupil of Rubens between 1598 (the year in which Rubens became a master) and 1600. He possibly studied under another master before becoming Rubens’ pupil. He also worked as an architect and military engineer for King Philip III of Spain.
