"North Wind" architectural decoration

This fellow looks out from the peak of the Sioux Falls Coliseum. When I first noticed him, I knew he was some type of deity from mythology based on his crown and classical appearance. I assumed he was Poseidon (or his Latin counterpart Neptune). I found out from research at the local historical society that he is supposed to be Boreas (Aquilon is his Latin counterpart) the North Wind. It is a little odd since he actually looks eastward! You can see him from N. Dakota Avenue in the 500 block just north of the immediate downtown area. Source: Objaverse 1.0 / Sketchfab
