Mercury.
The italic patron god of circulation, received his first Roman temple on the Aventine in 459 BCE. Mercury (or Mercurius) may have been transformed almost directly from the Greek tradition.

Mediator between gods and mortals, between the dead and the living, and always in motion, Mercury is also a deceiver, since he moves on the boundaries and in the intervening space; he is patron of the shopkeeper as much as the trader, the taveller as well as the brigand."
