The date of birth of the Amigoni, that had been open to discussion in artistic literature for a long period and fell anywhere between 1605 and 1665, was finally fixed with certainty only in 2006 after careful research in the parish archives of the church di Sant'Agata.
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.
We can still find it in the church of Santa Maria dei Miracoli in Brescia with the paintings of 1648 of the Immaculate Conception and Presentation in the Temple of Mary (the first half-destroyed and the second completely destroyed in 1944 during a bombing), then again in Chiari, Paitone and Zone.
Here he performs for the parish church a Madonna with Child, St. George, St. Rocco and a devotee, another masterpiece, where his experiments reached a certain stability, allowing the artist to return to the lessons learned at the beginning of his training and enrich them with the new, well-established baroque style.
For two years (1655-1656) Amigoni returns to painting frescos with the internal frieze of the church of Santa Maria della Carità in Brescia, executed together with Agostino Avanzo and now lost, and with the decoration of the Villa Togni salon in Gussago, created in collaboration with the young Pompeo Ghitti.
