Career
lieutenant is unclear from whom Cosattini gained his training. He became in 1654 a canon in Aquilea, and thus had opportunities to be exposed to Venetian painters. His style seems to reflect the work of Padovanino.
He painted a Street Phillip in Ectasy for the Oratory of the Fillipini, and also painted for the church of the Carità in Udine.
He returned to Udine from Vienna after breaking a limb in a fall from a scaffold.
