What symbol represents protection and royal power in Egyptian mythology?

The story behind the answer

Eye of Horus is correct because this ancient symbol—also called the Wedjat—stood for protection, royal authority, and health. In myth, Horus lost his eye fighting Set; the god Thoth restored it, making the eye a sign of healing and wholeness. Pharaohs and commoners alike wore Eye of Horus amulets to ward off harm, and it was painted on coffins and boats for safe passage.

To remember: an eye protects what it watches. By contrast, the ankh means life, the scarab beetle symbolizes rebirth, and the lotus represents creation and renewal. The Eye of Horus also had practical use: its parts represented fractions in ancient Egyptian measurement, reinforcing its association with order and restoration.
