Portrait of a Man, ca. 1470, Oil on wood, Overall 12 x 8 1/2 in. (30. 5 x 21. 6 cm) ; painted surface 11 5/8 x 8 1/8 in. (29. 5 x 20. 6 cm), Paintings, Dieric Bouts (Netherlandish, Haarlem, active by 1457?died 1475), Carefully observed details, such as the loose skin beneath the eyes and the creases by the mouth and brows, create an appearance of earnestness that is characteristic of Bouts's work. The panel has been cut down on all sides; it is unclear whether this is an independent portrait, or if it once formed part of a religious triptych or larger composition
