This symbol which consists in a painted eye under which there was the typical sign of the head of a falcon, means “the who has good health”. It is the eye of the Horus hawk, who, originally was itself the eye of the god of the sky, the Sun.
When Ra took the solar eye, in the ancient reign, Horus’s eye became the eye of the moon.
Taken away from Horus by Seth in the time of their legendary fights it was successively given back to his owner when he defeated the enemy. The eye udjiat is represented in many tombs and has become in time one “of the most used amulets by the Egyptians”.
