R. E. Francillon, Gods and Heroes; or, The Kingdom of Jupiter
“ Instead of punishing him, however, Jupiter was so delighted with his cleverness and impudence that he made Mercury his chief messenger and cup-bearer. He also gave him a winged cap, wings for his heels, a short sword, and a scepter called caduceus—a rod round which two living serpents coiled. The winged cap was called petasus, and whenever he put it on he became invisible; the wings for his heels were called talaria, and made him able to fly faster than lightning to any place he pleased. The caduceus was a magic wand. ”
