He is widely considered to have been the first important print publisher in France and to have contributed significantly to spreading awareness of contemporary artists' work throughout Europe.
[2] In 1624–1625 he was associated with Vignon as an art dealer (paintings) and acted as a print collector for Thomas Howard, 14th Earl of Arundel, and Charles I of England.
[4] In 1629, on his way to Italy, he collaborated with Matthieu Fredeau, a painter from Antwerp, on the Rosary altarpiece of the Dominican church of Aix-en-Province.
[2] About this time he began his career as a print publisher, producing illustrated books in collaboration with Melchior Tavernier, and becoming a master in the bookseller's guild on 26 October 1634.
He set up his own business at the sign of the 'Colonnes d'Hercule' on the rue Saint-Jacques, Paris, shortly before his marriage to Madeleine de Collemont in 1637.
