By 1668-1669 he had moved to Paris where he formed part of the group of Flemish artists who had congregated around Charles Le Brun and resided at the Hôtel Royal des Gobelins. The court painter (Premier peintre du roi) Charles Le Brun had been put in charge of the Gobelins Manufactory, the royal tapestry works created in 1663 as well as the decoration of the various new buildings being constructed for the King. To realize these projects Le Brun surrounded himself with a large group of artists including a number of Flemish artists such as the sculptor Gerard van Opstal and the painters Adam Frans van der Meulen, Abraham Genoels, Adriaen Frans Boudewijns and Peter van Boucle. As a resident of the Hôtel Royal des Gobelins, Boel could practice his art without having to register with the local Guild of Saint Luke or the Académie royale de peinture et de sculpture. On three occasions, his name appears in the "Comptes des Bâtiments du Roi" (Accounts of the Royal Buildings), including for providing designs for the Gobelins tapestry works. Boel was closely related to two Flemish artists, who also lived at the Gobelins: Adam Frans van der Meulen and Gerard Scotin, an engraver. In 1671 he was a witness to the wedding of Scotin. Van der Meulen's wife was the second witness. Scotin engraved a number of Boel's designs of animals and may also have been the publisher of engravings made by Boel himself.
