Hermes

Hermes (Greek, Ἑρμῆς, IPA: /ˈhɝmiːz/) is the messenger of the gods in Greek mythology. An Olympian god, he is also the patron of boundaries and of the travelers who cross them, of shepherds and cowherds, of thieves and road travelers, of orators and wit, of literature and poets, of athletics, of weights and measures, of invention, of general commerce, and of the cunning of thieves and liars.[1] His symbols include the tortoise, the rooster, the winged sandals, and the caduceus. The analogous Roman deity is Mercury.

Comment: I can only see the literature connection with the Butterfly types (ESFP). I am not sure I understand the Tortoise (it seems like the opposite) or the caduceus (which seems like ENTP).
