Answer:
the symbolic meaning of the ibis
Step-by-step explanation:
Champollion was a scientist who was focused on Egypt and hieroglyphs, and he is famous for their translation. The passage explains his process of deduction and understanding of the symbols.
Champollion knew that the bird of ibis symbolizes the god Th*ot, protector of magic and knowledge. He gathered this from his earlier learning of the Greek books. Therefore, he realized the hieroglyphs presenting the ibis had something to do with this god. By deduction, he realized they represent the name of the pharaoh Thothmes which means “Child of Th*ot”
