In 1644 he is recorded residing among the circle of Flemish and Dutch artists active in Paris, which included Jacques Fouquier, Philippe Vleughels, Willem Kalf, Nicasius Bernaerts and Peter van Boucle.
[6] Pieter van Mol was mainly a painter of religious subject matter, and to a lesser extent, of stories from Antiquity.
[1] The style of van Mol is varied ranging from a precise and fixed execution bordering sometimes on the archaic such as in the Lamentation of Christ (Musée des beaux-arts de Valenciennes), which is almost an homage to the Flemish Primitives.
His frescoes in the chapelle du Sacré-Cœur in the Église Saint-Joseph-des-Carmes and the Deposition in the Louvre show his debt to Rubens.
[5] Pieter van Mol was active as a portrait painter but his works in this genre are only known through engravings and some head studies.
A composition entitled Flemish dance was in the collection of the Palais Royal and was engraved by Carl Guttenberg between 1786 and 1808.
[10] Reportedly, the sale in Antwerp of prints after Pieter van Mol's work caused something of a scandal as they were considered more indecent than those of Agostino Carracci.
