Under Rubens's direction or influence a whole school of first-rate artists flourished in Antwerp. The volume of his work is enormous, and though he did little but supervise much of the work attributed to him, his domination was so absolute that almost everything proceeding from his workshop shows the mark of his style. He explored all fields of painting. In landscape, portrait, genre, and animal painting he was as supremely successful as in his large religious and allegorical works; smaller pictures include Helen Fourment and Her Children (Louvre) and Peasant Dance (Prado). Contemporaries doubted the durability of his delicate glazes, but his pictures are singularly well preserved. More than 2,000 paintings have been attributed to Rubens's studio.
