Face Spewing into Fountain

A fountain in an entrance in a building across the River on Barclay Street. An identical fountain was directly across from this one, on the other side of the entrance. It was like the fountain was cut in two, then affixed to the wall, with these the two faces of Janus. Janus had two faces because he could see both the past and the future, for the Ancient Romans, symbolizing barbarity and civilized society, like the Romans themselves. He was also the god of entrances, gates, bridges and passages. I’m assuming this is Janus because I do not know the Roman god of the spew.
