A detailed 16th-century engraving of a horse by Flemish master Hieronymus Wierix, featuring precise line work and a classical background.

This engraving, titled Thessalus, is a work by the Flemish master Hieronymus Wierix. It belongs to a series of horse studies, often associated with the designs of Jan van der Straet, known as Stradanus. The print captures a horse in profile, rendered with the technical precision characteristic of the Wierix family, who were prolific engravers in Antwerp during the late sixteenth century.

The horse stands on a rocky outcrop, its form defined by fine, controlled hatching that models the musculature and the texture of its coat. The mane and tail are depicted with flowing, rhythmic lines, suggesting movement despite the animal's stationary pose. In the background, a distant townscape with towers and a sea view provides a sense of scale and atmosphere, typical of the period's interest in combining zoological study with classical settings.

Below the image, Latin inscriptions provide commentary on the animal's qualities, reflecting the era's fascination with the noble nature of the horse. The composition is balanced, with the horse occupying the primary space, while the surrounding environment remains secondary. The use of light and shadow creates a sense of volume, demonstrating the engraver's ability to translate complex forms into a two-dimensional medium. This print offers a glimpse into the intersection of scientific observation and artistic convention in the Low Countries during the Renaissance. It is a clear example of the high level of craftsmanship found in Flemish printmaking, where the focus remained on clarity of line and anatomical accuracy. The work remains a reference for those interested in the history of equine art and the technical evolution of the copperplate engraving process.
