Agostino Perrocchio (1720-1799), notary, friend of Giuseppe Macchi, another great benefactor of the hospital, nominated universal heir of a conspicuous legacy, the Ospedale Maggiore, which had already benefited during his life. The commission of the portrait is entrusted to Anton Francesco Biondi, a painter, who over the course of thirty years paints 12 portraits for Quadreria Ospedaliera and builds a beautiful portrait "set", with the figure, sitting with his will in one hand, dressed with elegance, with the face described in a realistic and expressive manner.
