The legend of the Colossi of Memnon
Even though the statues were built for and by Amenhotep III, the name Colossi of Memnon actually has no link to him at all. The name was a result of a legend that arose many centuries later; Memnon was a hero in the Trojan War who was killed by Achilles.
He was the son of the goddess Eos, the Goddess of the Dawn. Eos was devastated to hear about her son’s death, so she asked the gods to allow him to visit her once a day. Her wish was granted and her son would begin to visit her every morning at dawn.
During the Greek occupation of Egypt, an earthquake in 27 B.C. significantly damaged the statues, leaving a crack that produced a sound similar to a whistle every morning with the passage of the morning winds.
People believed this to be Memnon calling his mom, making the statues a symbol of good luck with mystical powers similar to that of an oracle.
This led to people praying to the monuments. A few centuries later, religious movements that came to Egypt saw this as an act of pagan worship and the Colossi of Memnon were heavily vandalized.
