The Brivio chapel, in the Basilica of Sant’Eustorgio (first chapel on the right) was built in 1484 and subsequently remodelled several times.
On the left side is the sepulchral monument of Giacomo Stefano Brivio (deceased in 1486) created by Tommaso Cazzaniga and Benedetto Briosco, who was entrusted with the task of completing what another important sculptor, Francesco Cazzaniga, had begun a few years earlier. The tomb is structured according to the most widespread type of funerary monument in Lombardy and is composed of an ark, supported by candelabrum columns, with five bas-reliefs, representing, from left to right; the Annunciation, the Nativity, the Adoration of the Magi.
At the back of the chapel there is a triptych by Ambrogio da Fossano called Bergognone, datable, as suggested by documents, to the end of the 15th century and representing a Madonna and Child, Saint James and Saint Henry. Originally the panels were probably enclosed in a rich wooden architectural frame. The four small panels, representing St. John the Baptist, St. Sebastian, St. Catherine and St. Alexander, today placed with a completely arbitrary criterion under the side panels of the main register were originally placed in correspondence of the four vertical columns of the frame that divided the three panels.
While for the main register there are no attributive uncertainties, the not particularly sustained quality level suggests an intervention by the Bergognone workshop for the smaller tablets.
