IIRC Lake Moeris had a couple of Colossi built by Amenhotep III that were present up to the 18th century CE and have since disappeared. Archeologists in the 1930s found the two large platforms that they once stood upon.
Herodotus probably saw the Colossi and exaggerated their size due to part of the platforms being submerged and his imagination running wild.
Two of Amenhoteps III’s Colossi, he built quite a few of them, still exist in Luxor so you can see what they could have looked like:
People who hate Herodotus are just so freaking annoying. Then again, most Egyptologists are either sheep or jackasses, IMHO.
West of the Nile River near Luxor the Colossi of Memnon have been reported to sing at sunrise and sunset according to Strabo, Pliny, Pausanias, Tacitus, Philostratus and Juvenal
