"we were suddenly faced by a massive statue of the god Pan"

 Pan is the Greek God of shepherds, sheep, mountain wilderness and folk music. He is also responsible for inflicting pan pipes on the world.

Pan has the legs and tail of a goat, the body of a man, and horns on his head; his image has been co-opted by the Christian faith as that of the Devil. When he wandered through the Greek mountains, chasing nymphs and playing his infernal pan pipes, his invisible presence would make lonely goatherds 'panic'.
