A precise study of a horse in black and white chalk on blue paper by the Dutch artist Tethart Philip Christian Haag.

This study by Tethart Philip Christian Haag captures the physical form of a horse with precision and technical restraint. Executed in black and white chalk on blue paper, the work relies on the mid-tone of the ground to provide depth, while the white chalk highlights define the musculature and the sheen of the animal's coat. The artist, a German-born painter who spent his career in the Netherlands, was known for his ability to render animals with anatomical accuracy.

Haag focuses on the profile of the horse, presenting the subject in a static, dignified pose. The lines are controlled, reflecting the disciplined approach common to late eighteenth-century draughtsmanship. The artist avoids unnecessary background detail, allowing the viewer to concentrate on the structure of the animal, from the curve of the neck to the stance of the legs. The use of blue paper was a common choice for artists of this period, as it allowed for a balanced application of light and shadow, creating a sense of volume without the need for extensive shading.

This piece is representative of the period's interest in documenting specific animals, often commissioned by owners to record the appearance of prized mounts. The composition is balanced and clear, demonstrating the artist's command over his medium. By using the paper colour as a primary element of the image, Haag achieves a subtle tonal range that brings the subject to life. The work remains a fine example of the technical skill required in animal portraiture during the late eighteenth century, prioritising clarity and anatomical correctness over decorative flourish.
