The boldness and rapidity of Salvator Rosa's pencil, aided by the fertility of his highly poetical imagination, enabled him to paint an immense number of pictures while he was at Florence; but not finding sufficient leisure to follow his other pursuits, he retired to Volterra, after having resided at Florence nine years, respected and beloved by all who knew him. The three succeeding years were passed in the family of the Maffei, alternately at Volterra and their villa at Monte Ruffoli, in which time he completed his Satires, except the Sixth, "L'Invidia;" which was written after the publication of the others. He also painted several portraits for the Maffei, and among others one of himself, which was afterwards presented to the Grand Duke of Tuscany, and placed in the Royal Gallery at Florence.
