But Rubens was the head of a school of painting--the later Flemish school. His studio was thronged with young artists, who were assistants as well as students. With his keenness of observation directed to a line of business, the master quickly discovered what each pupil could do best, and set him at that part of a composition. In this way Rubens was enabled to produce the immense number of pictures that bear his name--thirteen hundred have been catalogued. One student would paint nothing but landscapes, another all the animals, while the teacher put in the most important parts and added the finishing touches to the whole. There was no deceit in this method of working, for the amount of Rubens' own work a given piece contained depended upon the price his clients were willing to pay. The design was always his, but those who paid the lowest price got nothing but the design from his hand, while his wealthy patrons who could afford the maximum received pieces that were entirely his own handiwork, and between the two extremes there were all grades of collaboration.
Jacob Jordaens was one of the most famous of Rubens' pupils. It is said that "they are of the same family and the same temperament; and Rubens stands between Jordaens and van Dyck. Rubens is gold, van Dyck silver, and Jordaens blood and fire." The latter was an indefatigable painter and a rapid worker, often completing a portrait at a single sitting. He covered a wide range of subjects, religious, allegorical, landscapes, portraits and animals, and he succeeded so well that "there are Jordaens attributed to Rubens and Rubens to Jordaens."
Anthony van Dyck was another pupil of the great master, and the aristocrat of the famous seventeenth century Flemings. He was only a boy among boys, quite undistinguished, until one day chancing to rub against a painting of his teacher's on which the paint was still wet, he retouched it so skilfully that it turned out better than before. In time he became so formidable a rival, in spite of his youth, that Rubens sent him off to Italy to study. He came back in four years, greater than ever. A few years later, Rubens contrived to have him called to England as court painter. During the time that he remained in Flanders he produced several religious pictures, among them the Raising of the Cross, at Courtrai, and a Crucifixion, which, before the war, was in the Cardinal's palace at Malines. The same Red Cross worker who rescued the Rubens from destruction at Malines also brought away this composition, of which he says, that it had been cut out of its frame the day before, rolled up, and stowed away in the cellar. But van Dyck's best work was done in portraiture, and in this he was "nearly the equal of Titian."
