Agostino Tassi (born Agostino Buonamici, Perugia, 1578 – Rome, 1644) was an Italian landscape and seascape painter, who was convicted of raping Artemisia Gentileschi in 1612. Because he aspired to nobility he modified the details of his early life. Though he was born in Perugia he claimed to have been born in Rome. His family name was Buonamici, but Agostino adopted the surname Tassi to give substance to his story that he was adopted by the Marchese Tassi. He was actually the son of a furrier named Domenico.
