There is little information regarding the biography of this artist. The son of a carpenter originally from Florence, he was born in Rome in 1574, where he had his first training in an artistic environment with a purely late mannerist taste. He probably moved, together with his half-brother Giulio Lasso, painter and sculptor, to Sicily and, later, to Spain, where he married and developed his own artistic language. Returning to Italy in 1605-1606, he arrived there at the height of Caravaggio's Roman activity, but had tense personal relationships with the great Lombard painter, as evidenced by his only direct biographer, Giovanni Baglione.
