This portrait of a lady connected to one of the greatest families of Milan bears witness to the international nature of the Trivulzio collection and the prestige of the artists within it. The painting is signed by the artist and the masterly paint application, passing from fabrics to flesh tones with the finest of brushstrokes, confirms its attribution. The silvery and blue tones are also significant as the artist's chromatic signature, here in its mature phase. The woman is portrayed with the classic half-length setting and the painting appears to be a real likeness, without being tempted to idealise the subject.
