and his decision to leave Antwerp in 1643 may have had something to do with malversations relating to the Guild's funds. Although successful, van Thulden seems to have been regularly in dire straits. In 1640 he received a commission from his home town 's-Hertogenbosch to create political allegories for the city hall. In 1643 Theodoor had left Antwerp and lived in Oirschot where he became a citizen in October 1644. By 1646 or 1647 van Thulden had moved to 's-Hertogenbosch. Van Thulden continued to paint altarpieces and other commissions for Catholic patrons in the Southern Netherlands as well as political allegories, many related to the 1648 Peace of Westphalia. In the period of 1648-1651 he also participated in the decorations for the Oranjezaal in the Huis ten Bosch, The Hague, a commission for Amalia von Solms on which worked Dutch and Flemish artists such as Gerard van Honthorst and Jacob Jordaens. In 1656-1663 van Thulden designed pattern boards for the glass artist Jean de Labarre for three large glass windows for the Our Lady Chapel in the Cathedral of St. Michael and St. Gudula in Brussels. Van Thulden was the tutor of painter Hendrick van Balen the Younger. Theodoor van Thulden died in 's-Hertogenbosch on 12 July 1669. Work Van Thulden painted altarpieces, mythological subjects, allegorical works and portraits. His style was initially influenced by the Mannerism of the School of Fontainebleau but he later became influenced by Peter Paul Rubens, with whom he frequently collaborated. He played an important mediating role by bringing aspects of Flemish Baroque painting into the Dutch Republic. Gradually van Thulden's work became more elegant and he evolved towards a certain Classicism. Van Thulden explored the portrait genre and made group portraits of important families as well as individual portraits of prominent people from local political and religious circles. In some of these works van Thulden created a portrait style that included allegorical allusions and attempted to recapture the elegance and delicacy of van Dyck's portraits. Van Thulden also specialized in large allegories with a political message. His skill in this area is demonstrated by the decorations he made for the City Hall of 's-Hertogenbosch. He is known to have painted Justice and Concord (1646), The Right of the Four-Quarters of the Meierij District to Appeal Before the Court of 's-Hertogenbosch (1647) and The Request for Admission to the Union (1650). These works still hang
