See Perkins, Italian Sculptors, p. 109, for a description of the Arca di S. Agostino, which he assigns to Matteo and Bonino da Campione. This shrine, now in the Duomo, was made for the sacristy of S. Pietro in Cielo d'Oro, where it stood until the year 1832.
Bonino da Campione, the Milanese, who may have had a hand in the Arca di S. Agostino, carved the tomb of Can Signorio. That of Mastino II. was executed by another Milanese, Perino.
