Udjat

This important symbol is named after the 'sound eye' of Horus. According to one version of the legend Seth, the god of evil intentions, snatched away the eye of Horus which then fell to pieces. Thoth found it and put it together again. The udjat was regarded as a powerful protective amulet; it is frequently found in tombs, on coffins and on the sea
