It is Rome which gives the leading idea also to Poussin's art. He has been called the "Raphael of France"; and certain it is that at a time when the local art of France was purely decorative in character, he returned, and strenuously adhered, to classical traditions. Already at Paris he had studied casts and prints after Raphael; and when he first went to Rome he lived with Du Quesnoy ("Il Fiammingo"), under whom he learnt the art of modelling _bassi-relievi_. He also studied anatomy, and attended the academy of Domenichino, whom he considered the first master in Rome. His profound classical learning has caused him to be called "the learned Poussin." "He studied the beautiful," says his biographer, "in the Greek statues of the Vatican." "He studied the ancients so much," says Sir Joshua Reynolds, "that he acquired a habit of thinking in their way, and seemed to know perfectly the actions and gestures they would use on every occasion." His learning went, however, farther than this in its influence on his art. His ideal, says Lanzi, was that of "philosophy in painting"; and in one of his letters Poussin illustrates the idea from the Greek theory of "modes" in music. If a subject were serious, it should be painted in the Doric mode; if vehement, in the Phrygian; if plaintive, in the Lydian; if joyous, in the Ionic.[72] This classical learning of Poussin was the source at once of his strength and of his weakness as an artist. On the one hand, it often made his work wonderfully harmonious and impressive. Thus in the Ionic mode, his Bacchanalian pictures in this Gallery and elsewhere are nearly the best representations in art of the Epicurean ideal of life, of a world in which enjoyment is the end of existence. "His best works," says Ruskin, "are his Bacchanalian revels, always brightly wanton, full of frisk and fire; but they are coarser than Titian's[73] and infinitely less beautiful. In all minglings of the human and brutal character he leans on the bestial, yet with a sternly Greek severity of treatment." Again, in more serious Doric mode, he is "the great master of the elevated ideal of landscape." He does not "put much power into his landscape when it becomes principal; the best pieces of it occur in fragments behind his figures. Beautiful vegetation, more or less ornamental in character, occurs in nearly all his mythological subjects, but his pure landscape is notable only for its dignified reserve; the great squareness and horizontality of its masses, with lowness of tone, giving it a deeply meditative character:" see especially 40. On the other hand, he had the defects of his training. It made him too restrained and too cold. "His
