A Nymph on a Dolphin 

"A Nymph on a Dolphin" is a bronze medal by Francesco Marti, an Italian Renaissance artist, who lived from 1489 to 1516. The medal, cast in bronze, depicts a nude nymph riding a dolphin, her flowing hair and drapery adding a sense of motion and dynamism. This piece exemplifies the intricate detail and classical motifs that characterized Italian Renaissance art. The medal's small size (4.5 cm) speaks to the growing interest in collecting and appreciating miniature works of art during this era.
