In Greek mythology, the god APOLLO (also: Apollon) was associated with, among other things, the famous oracle of Delphi. According to tradition, the last oracle of Phytia (this was the title of the seer/fortune teller who lived there) in the second half of the fourth century - i.e. when Christianity was spreading more and more - is said to have been: "Tell the king that the beautifully constructed house has fallen. Phoibos Apollon has no refuge anymore, the sacred laurel is withering, its springs are silent forever, the murmuring of the water has ceased."
