For me, this is really a controversial piece of hieroglyph in the temple of Abydos. Some people (who claim that Egyptians had some contact with aliens) believe that this hieroglyph is real and in its original form.
Some others say that the carving was altered by the successors of Ramses II (maybe Merneptah). It was a common practice among Pharaohs of Egypt to destroy the symbols and glory of their forefathers in order to showcase themselves. An example is Hatshepsut’s temple at Deir el Bahri, where statues and wall paintings were destroyed by her own son.
hieroglyph in the temple of Abydos2
The temple of Abydos was built by Seti-I and finished by his son Ramses II, the greatest of all pharaohs. So it is natural that his successors tried to erase the trace of Ramses II from the minds of common people and brought their own image to the front.
