Sigismondo on a Charger before a Fortress [reverse]

Pisanello

National Gallery of Art

The image shows a circular relief sculpture of a mounted soldier on a horse. The soldier wears a helmet with a long plume and appears to be in motion, with one arm pointing forward. The horse is adorned with detailed armor or drapery. The background includes architectural elements like a detailed building, a shield bearing a coat of arms, and what looks like a tiled rooftop.. The sculpture is made of a dark, likely metallic material with a gray finish, and has engraved text and numerals along its edges. The scene appears to be a static relief, reminiscent of medieval or Renaissance iconography.
