Rosa da Tivoli unfortunately fell into extravagant and dissipated habits, which frequently caused him great inconvenience. From his facility, he multiplied his pictures to such an extent as greatly to depreciate their value. It is related that he would sit down, when pressed for money, dispatch a large picture in a few hours, and send it directly to be sold at any price. His servant, possessing more discretion than his master, usually paid him the highest price offered by the dealers, and kept the pictures himself, till he could dispose of them to more advantage.
