This goblet shows a nearly circular rocaille cartouche framing the bust of a clergyman, with books in the background on the right. The finesse and density of the stipple engraving provide the basis for the attribution to David Wolff (1732–1798), a celebrated master of this technique in the last quarter of the 18th century. Wolff regularly depicted men of political or cultural importance, but it is rare to see a portrait together with personal attributes. The subject of the portrait may be Jacob van Nuys Klinkenberg (1744–1817), a respected cleric and theologian in the northern Netherlands, who was appointed chairman of the theology department at Amsterdam University in 1784, about the time this wineglass was decorated. Wolff typically decorated goblets with the kind of baluster or faceted stems that were originally made in Newcastle upon Tyne, England, or the southern Netherlands. Stylistically, these glasses fall within the late Rococo and neoclassical periods. Wolff’s restrained Rococo-style engraving remained popular to the end of the 18th century.
