The motif of Eros riding a dolphin is known in Greek art from the middle of the 6th century BC, especially in ceramics and decorative arts, as an allegory of love. Eros riding a dolphin doesn’t seem to be connected to a specific myth and it appears to have been used only for decorative purposes. In Ancient Greek and Roman culture and mythology dolphins were associated with the sea and with the sphere of sensual love, bearing an amatory symbolism. Because of the assonance between the ancient Greek word delphis (δελφίς), meaning dolphin, and the word delphus (δελφύς), meaning womb, dolphins were considered animals sacred to Aphrodite, the Greek goddess of love, fertility and desire.
