St. Lucas- of schilders- en konstwerkersgilde van Rotterdam, gildepenning van Pieter Ryckx, beeldhouwer c. 1666 - 1672

This oval-shaped bronze medal, created by an anonymous artist, dates back to the 17th century. The front depicts a bull's head framed by a wreath of leaves, with a shield bearing three crescents in the center. On the reverse side, the name "Pieter Ryckx" is inscribed on a banner, along with several tools: a chisel, hammer, and a palette. This medal is likely a guild medallion, indicating membership of Pieter Ryckx, a sculptor, in the Saint Lucas guild of Rotterdam, an association for painters and artists.
