playwrights, and painters—the so-called Accademia dei Percossi (Academy of the Stricken). To the rigid art milieu of Florence, he introduced his canvases of wild landscapes; while influential, he gathered few true pupils. Another painter poet, Lorenzo Lippi, shared with Rosa the hospitality of the cardinal and the same circle of friends. Lippi encouraged him to proceed with the poem Il Malmantile Racquistato. He was well acquainted also with Ugo and Giulio Maffei, and was housed with them in Volterra, where he wrote four satires Music, Poetry, Painting, and War. About the same time he painted Philosophy, now in the National Gallery, London.

Rosa's tempestuous art and reputation as a rebel gave rise to a popular legend—recounted in a biography of Rosa published in 1824 by Sydney, Lady Morgan—that Rosa lived with a gang of bandits and participated in the uprising in Naples against Spanish rule.

To confute his detractors he wrote the last of the series, entitled Envy. Among the pictures of his last years were the Saul and the Witch of Endor and
