Theodoor van Thulden (1606–1669) was a Flemish Baroque painter, draughtsman, and printmaker from 's-Hertogenbosch. His artistic journey began with local training in his hometown, but it was his move to Antwerp that shaped his career. In Antwerp, van Thulden joined the Guild of Saint Luke and worked in the workshop of Peter Paul Rubens, a major influence on his style. Rubens' dynamic compositions and dramatic use of color had a profound impact on van Thulden’s approach to art. Van Thulden collaborated with Rubens on several significant projects, including the decoration of Antwerp for the triumphal entry of Cardinal-Infante Ferdinand in 1635. He also completed independent commissions, such as a series of religious paintings for the Abbey of Saint-Germain-des-Prés in Paris. As a printmaker, van Thulden produced engravings based on Rubens’ designs, which contributed to his growing reputation. His style combined the grandeur of Rubens with a more personal refinement, and his works often depicted mythological, allegorical, and religious themes. Van Thulden's legacy as a key figure of the Flemish Baroque is preserved in major museums across Europe, including the Louvre and the Prado. He passed away in his hometown in 1669.
