Hermes

…

…not to be detected, Hermes put shoes on their feet and brought them to Pylos, hiding the rest in a cave. He sacrificed two and returned to Cyllene. There he found a tortoise, and having strung its shell with chords made of the cattle he had sacrificed, he produced a lyre and invented a plectrum too. The golden wand, the Caduceus, is a staff of riches and wealth, which keeps Hermes safe from all harm.
