He apparently quickly worked independently then rejoined his friend and fellow Bolognese and Baglione pupil, Lionello Spada. Together during the early 17th century, they began to collaborate in quadratura, with Curti painting the structures, while Spada painted the figures. They soon parted, with Spada becoming a canvas painter, and Curti was to travel to paint in Modena, Parma (1618 and 1630), Rome (1623) and Genoa.
