 In the early 1640s, still for unknown reasons, he traveled to Switzerland and left the altarpiece of the "Perdon d'Assisi" in the church of San Francesco in Ruis, in the Surselva District, signed and dated 1642.It is therefore his first work, which has reached a certain attribution after the two frescoes of 1633.This work was also the beginning of the most prolific period of the painter, which lasted twenty years until his death.
