Detail of Aristotle's face ; Signed and dated on pedestal of bust: Rembrandt. f. / 1653. In this imaginary portrait of Aristotle, the Greek philosopher rests his hand reflectively on a bust of Homer, the epic poet of an earlier age. A medallion depicting Alexander the Great, whom Aristotle tutored, hangs from the gold chain. This extravagant decoration must be an award for service and recalls the gold chains that princely patrons gave to Titian, Rubens, and van Dyck. It is generally supposed that Aristotle is contemplating the worth of worldly success as opposed to spiritual values. The gestures of the hands, accentuated by the cascading sleeves, and the shadows playing over Aristotle's brow and eyes support this interpretation. The picture was painted for the great Sicilian collector Antonio Ruffo. (http://www.metmuseum.org)
