Addax nasomaculatus (Addax)

This monochromatic print depicts an Addax antelope shown in full-body profile facing toward the left. The animal features distinctive long, spiraling, curved horns and a coarse coat of fur around the neck and chest. The drawing uses hatched lines to create depth and shadow, rendering the musculature of the legs and the texture of the coat. The animal stands on a simple, lightly sketched ground line.

This image is a plate from Ernst Haeckel's 'Kunstformen der Natur' (Art Forms in Nature), a seminal work that bridged the gap between biological observation and aesthetic ornamentation in the late 19th century.
