This symbol dates back to the 1400s, but has always been associated with Lucifer. According to contemporary Christianity, Lucifer was a fallen angel of God who was cast down from heaven for challenging God, both in power and challenging God's views of the expecting worship. Lucifer took pride in his power, which was the 7th and deadliest of all the sins, and when questioning God, was damned for eternity in Hell. Stainless Steel 316L - Including Chain.
