Willem (Guillaume-Jacques) Herreyns, Flemish painter and teacher. Because his work continued the tradition of 17th-century Flemish painting, he has long been considered as the last of the school of Rubens and opposed to innovative trends. However, although it is true that most of his religious works remained faithful to the traditionalist mainstream, his friendship with Andries Cornelis Lens and Jan Cardon, his teaching and his political ideas all show open-mindedness towards new ideas. //
