Few artists could match Moroni's skill in depicting the appearance of his sitters, far less his ability to conjure the inner workings of their minds. The identity of the gentleman in this penetrating portrait is a mystery. For a long time the painting was thought to be by Titian and to represent that artist's ideal of a schoolmaster. But according to another tradition, the picture got its name because Titian admired it and learned so much from it. Whether or not the older master ever saw this painting, Moroni's strong, simple composition and trenchant characterization did impress two later specialists in portraiture: Anthony van Dyck and Joshua Reynolds both made copies of it.
The subject, dressed all in black, sits in a Savanarola chair that is seen -- unexpectedly -- in profile. He rests one beautifully drawn hand on the arm of the chair and turns as if to regard the spectator. With his other hand he holds his place in a book, thoughts of which, judging from his absorbed gaze, still occupy his mind. The white, embroidered collar sets off the face, and the asymmetrical points echo the man's uneven features. Even the bristly textures of the trimmed whiskers and clipped, grizzled hair command attention.
