The artist, who was also a draughtsman and engraver, was born near to Turin.
At an early age, he moved to Rome, where he was much influenced by the work of Giovanni Lanfranco (1582-1647), which he closely imitated.
His work was further influenced by a period spent in Naples, where he eventually died.
