or DIETRICY, CHRISTIAN WILLIAM ERNST, a modern artist, who was born at Weimar in 1712. He resided chiefly at Dresden, where he was professor of the Academy of Arts. He was a painter of very extensive abilities, and succeeded both in history and landscape. We have by him a great number of small subjects, to the amount of 150 or more, which he engraved from his own compositions, in the style (says Bafan) of Ostade, of Lairesse, and of Salvator Rosa. Sixty of these etchings are exceedingly rare.
