Horus was an ancient sky god whose eyes were said to be the sun and the moon. However, he soon became strongly associated with the sun. In this myth it is specifically stated that it is Horus´ left eye which has been torn out, so the myth relates to the waxing and waning of the moon during which the moon appears to have been torn out of the sky before being restored once every lunar month. The Eye of Horus was believed to have healing and protective power, and it was used as a protective amulet. It was also used as a notation of measurement, particularly for measuring the ingredients in medicines and pigments. The symbol was divided into six parts, representing the shattering of Horus´ eye into six pieces. Each piece was associated with one of the six senses and a specific fraction. Item# MD5590.
