An eighteenth-century Dutch etching depicting a coppersmith at work, from the series Menselyk Bedryf.

This etching, titled De Koperslager, originates from the series Menselyk Bedryf (Human Occupations), published in Amsterdam around 1718. The work depicts a coppersmith at his workbench, captured in the act of shaping metal with a hammer. The composition is divided into two distinct zones: the interior workshop where the artisan focuses on his task, and a glimpse through an open doorway into a street scene where another figure continues the work.

The artist employs precise, linear hatching to define the textures of the metal vessels, the wooden stool, and the architectural elements of the workshop. The inclusion of text above and below the image provides a moralising context, common in Dutch prints of this period, which equates the physical labour of the craftsman with the spiritual refinement of the human soul. The scene offers a window into the daily life of an eighteenth-century tradesman, documenting the tools and environment of a metalworking shop with observational clarity.

Van der Sys utilises a balanced composition, drawing the eye from the central figure to the background activity. The print is characteristic of the period's interest in documenting various professions, often pairing technical observation with didactic verse. The fine lines of the etching process allow for the depiction of small details, such as the leaded glass windows and the various pots stored on shelves. This piece is a representative example of the genre prints that circulated in the Netherlands, serving both as a record of urban industry and a vehicle for philosophical reflection.
