horus was the egyptian god of the sky. he was the son of isis and osiris. after fighting his uncle, set (osiris and isis' brother) he became the king of egypt. during this fight, he lost his eye. the "eye of horus" became one of the most important symbols in ancient egypt and egyptian civilization. when horus lost his eye, his eye set out on a journey of its own. when the other gods tried to catch the eye, his eye began to cry. these tears became the first people of egypt in egyptian belief.
