The first known images of a pentagram date about 3500 BC, these are the five-pointed stars drawn on clay found in ruins of the ancient city of Uruk. Images of pentagrams meet also on the Egyptian statues. As Arthur Waite reports in the "New Entsiklopedii Frank freemasonry", Egyptians called a pentagram "psoglavy Anubis's star".
The pentagram was widely known as the sign preserving against any evil; the belief in its preserving properties was so deep that in Ancient Babylon it was represented on doors of shops and warehouses to save goods from spoil and theft. It also for devoted was a powerful sign of the power. So in the same Babylon, for example, this sign often meets on imperial seals, and, according to modern scientists (1), she personified "the power of the governor extending wherever one wishes light". According to other version, the most ancient designations of a pentagram symbolized the goddess Ishtar and a next world Duat (2).
At Jews the pentagram was associated with their sacred Pentateuch received by Moisey from God. Ancient Greeks called a pentagram the Pentalpha that means "five letters an alpha" as the symbol can be spread out to an alpha five times. For early Christians the pentagram was a reminder on five wounds of Christ: from a thorny wreath on a forehead, to nails in hands and legs.
