In fact, the prototype is pastoral pan.
Pan is a god who is half man and half beast, with a pair of goat horns on his head, a sheep tail and two legs on his lower body. He is the son of Hermes, and Hermes is a god who loves noise and joy. All the wilderness, jungle, forest and mountains are his hometown. He is the god of animal husbandry and mountain forest. Pan is also an excellent musician. He plays beautiful music with reed flute, which often attracts fairies in the mountains to listen to. Although Pan is an excellent musician, because of his appearance, every fairy he pursues is avoided, which often leads to tragedy, and the music played by Pan is far less than Apollo's lyre.
