Even his fugitive sketches, thrown off in the days of his poverty, have a quite peculiar charm and a thoroughly individual sentiment. There are vignettes of his for letter-sheets, done for the Government offices, which in a few pencil touches contain more manly elegance and poetry than do David's most pretentious compositions with all their borrowed Classicism. Prudhon was the only painter who at that time produced anything of conspicuous merit in the art of ornament. Even drawings such as "Minerva uniting Law and Liberty," which from their titles would lead one to expect nothing more than frozen allegories, are imbued, not with David's coldness, but with Correggio's charm. French grace and elegance are united, without constraint, to the beauty of line found in ancient cameos. He it was who first felt again the living poetry of that old mythology, which had become a mere collection of dry names. He is commissioned to draw a card of invitation for a ball, and he sends a tender hymn on music and dancing. In extravagant profusion he scatters forth, no matter where, poetic invention and grace such as David in his most strenuous efforts sought for in vain. It was during this time that Prudhon became the admirable draughtsman to whom the French school have awarded a place among their greatest masters. These drawings and illustrations were the necessary preparation for the great works which brought him to the front at the beginning of the century. Even his first picture, painted in 1799--to-day half-destroyed--"Wisdom bringing Truth upon the earth, at whose approach Darkness vanishes," must, to judge from early descriptions, have been marked by a seductive and delicate grace. And the celebrated work of 1808, "Justice and Vengeance pursuing Crime," belongs certainly, so far as colouring is concerned, rather to the Romantic than to the Classical era. For during the latter, one faculty especially had been lost, and that was the art of painting flesh. Prudhon, by deep study of Leonardo and Correggio, masters at that time completely out of fashion, won back this capacity for the French school. In wild and desolate scenery, above which the moon, emerging from behind heavy clouds, shines with a ghostly light upon the bare rocks, the murderer is leaving the body of his victim. He strides forth with hasty steps, purse and dagger in hand, glancing back with a shudder at the naked corpse of a young man which has fallen upon a ledge of rock, lying there stiff and with outstretched arms. Above, like shapes in the clouds, the avenging goddesses are already sweeping downwards upon him. Justice pursues the fugitive with threatening, wrathful glance; while Vengeance, lighting the way with her torch, stretches out her hand to grasp the guilty one. In that epoch this picture stands alone for the imposing characterisation of the persons, for its powerful pictorial execution, and the stern and grandiose landscape which serves as setting to the awful scene.
