Refined painting on panel depicting an elderly bearded man, attributable to Christian Wilhelm Ernst Dietrich (1712-1774). The work on panel shows an extraordinary mastery of the painting technique, with particular attention to the details of the face, beard, and expressive features. The man wears a voluminous headdress and a simple garment in warm tones, in stark contrast to the dark background that emphasizes his figure. The lighting is expertly managed, highlighting the wrinkles and skin texture, distinctive characteristics of the artist's style. A work of great emotional intensity and technical refinement, ideal for collectors of 18th-century art. The panel measures 23.5 x 19.5 cm, the new frame measures 35 x 31 cm.
