Temple of Janus
Nothing remains of the Temple of Janus of which we only have a representation on the back of a Nero coin. It was located not far from the Forum, along the Argiletum, the Vicus that passing between the Curia and the Basilica Emilia linked to the Suburra.
It was dedicated to the god Janus who presided at the beginning of each and every end, a Roman archaic deity of which we have no record of the Greek gods. Even his name is not yet clear on what is derived although seems connected to terms that indicate a movement, a crossing.
