A detailed etching by Paulus Potter depicting two cows in a field, showcasing the artist's mastery of animal anatomy and line work.

Paulus Potter was a specialist in animal subjects during the Dutch Golden Age. This etching, titled Staande en liggende koe, demonstrates his technical precision in capturing the anatomy and texture of livestock. The composition features two cows in a sparse, open field. One animal stands in profile, facing the viewer with a steady gaze, while the second rests on the ground behind it.

Potter employs a variety of hatching techniques to define the musculature and the coarse texture of the hides. The lines are controlled and deliberate, creating a sense of volume and weight. The background is kept minimal, with light horizontal lines suggesting a low horizon and an expansive sky. This focus on the animals themselves, rather than an elaborate setting, is characteristic of Potter's approach to printmaking.

His work reflects the seventeenth-century Dutch interest in rural life and the natural world. By elevating common farm animals to the primary subject of a fine art print, Potter challenged the traditional hierarchy of genres. The clarity of the etching process allows for a detailed observation of the cows, from the structure of their horns to the subtle shading of their flanks. This print provides a clear example of the artist's ability to render form through line alone, without the need for colour or complex tonal washes. It remains a representative piece of his output, which often prioritised the quiet, observational study of animals in their natural environment. The print is a study in balance, contrasting the verticality of the standing cow with the horizontal, grounded form of the resting animal.
