The eye of Horus is a symbol that has been handed down since ancient Egypt, and it is also one of the most impressive symbols in ancient Egyptian culture. The eye of Horus, as the name suggests, is the eye of Horus, the eagle headed God, with sacred meaning, representing the protection of the gods and the supreme monarchy. Ancient Egyptians also believed that the eye of Horus could play a role in resurrection. For example, the mummy of Tutankhamen, the 18th dynasty king of Egypt, was also painted with the eye of Horus.
According to legend, Horus's right eye symbolizes the complete sun. According to legend, because Horus defeated Seth, the right eye has the power to stay away from pain and defeat evil. Horus' left eye symbolizes the incomplete moon. According to legend, Horus later dedicated his left eye to Osiris. Therefore, Horus' left eye can distinguish good from evil and defend happiness. It also made ancient Egyptians believe that Horus' left eye had the ability to revive the dead. Around the world, many religions use the eye as a symbol of the amulet.
