A detailed seventeenth-century etching of two brill fish on a sandy shore, rendered with precise line work and scientific observation.

This etching by Jacques van Merlen depicts two flatfish, identified by the Latin and French inscription as Rhombus Laevis, or the brill. The work belongs to a broader tradition of seventeenth-century natural history illustration, where artists documented marine life with precision. The composition places the two fish centrally, their bodies overlapping on a sandy shore. Van Merlen employs fine, hatched lines to define the texture of the scales and the delicate fringe of the fins. The background is minimal, featuring a distant horizon line with faint outlines of sailing vessels, which provides a sense of scale and location without distracting from the primary subjects.

In the lower left corner, the artist includes a small collection of seashells, a common motif in maritime art of the period. The inclusion of the Latin name and the phrase 'Cum privil. Regis' indicates that this print was part of a formal series, likely intended for a collection of natural history plates or a decorative portfolio. The etching technique allows for a high degree of detail, particularly in the rendering of the fish eyes and the subtle variations in the sand. The work reflects the period's interest in taxonomy and the systematic observation of the natural world. By isolating the specimens against a sparse background, the artist directs the viewer's attention to the anatomical features of the brill. The print is a clear example of the intersection between scientific documentation and artistic craft in the seventeenth century, demonstrating the technical skill required to translate biological observation into a reproducible medium.
