Satanic Crosses from Smelly Cat's blog

Satan was not Crucified so a cross doesn't really figure in his story or iconography. Generally ancient Demons and Devils are portrayed as animal headed chimeras so a Baphomet or Pazuzu is far more Satanic than a Petrine Cross or the combined Lorraine Cross / Infinity Symbol or Sulphur (Sulfur/Brimstone) icon that heads the 9 Satanic statements page in the Satanic Bible. Most of this Cross business seems to come from teenagers either angry at Christianity or looking to be edgy with symbolism as nothing more than a fashion statement, accessorizing their way through life with badges, tattoos and pendants. Prior to the Roman Empire establishing the Cross as the symbol of Christ under the rule of Constantine the symbol of Christ was a fish, and still is to a lot of Christians. Satan predates Christ by a great many centuries so he's hardly gonna be defined by another religious figure's icon.
