The term 'God of North Wind' is referring to the Greek god Boreas. Boreas was the god of the cold north wind and winter. He was often depicted as a winged old man with a shaggy beard, holding a conch shell and wearing a billowing cloak. He was the son of Eos, the goddess of the dawn, and Astraeus, the god of the dusk. He was also the father of Zetes and Calais, two winged sons who were Argonauts.
