A very early and rare miniature, enamel on copper, done circa 1690-1700 by Peter Boy the Elder (1651-1727). The sitter is Johann Wilheim II. He was Elector Palatine (1658–1716) of the Wittelsbach dynasty and was Duke of Neuburg (1690–1716), Duke of Jülich and Berg (1679–1716), and Duke of Upper Palatinate and Cham (1707–1714). From 1697 onwards Johann Wilhelm was also Count of Megen. Clearly a busy and well titled fellow.
The miniature is in its original gold mount on a 19th century sterling ring. Sight size is 1 1/8" by 7/8". The ring size is in the 6 1/2 to 7 range. As to be expected, there are some scratches to the enamels, but a great piece, Please keep in mind that the large photos greatly exaggerate the visual impact of the scratches.
Notes: 1. This is from the extensive and highly important collection of Ernst Ludwig of Hesse (cf Table 25, Item 74 in the book about this collection).
2. Due to its early date and rarity, I could find no other works done by Peter Boy the Elder that have come up at auction but there were two done by School of Peter Boy artists. No date was associated with them and they were done much later than when Boy lived. Boy was considered by many to be the most accomplished German enameler of his time.
