Christ among the Doctors

From the Rijksmuseum record

The drawings by De Weerdt (on the adjacent wall) were transformed into engravings by Isaac Duchemin, a Netherlandish-born printmaker who, like De Weerdt, had settled in Cologne. The skilled engraver followed the designs extremely closely, translating De Weerdt’s painterly compositions into a dense network of lines, crosshatches, and dots. As a result of the printmaking process, the compositions appear in reverse.
