Tattoo of crosses | Mexican Tattoo Design
The cross has been used as a symbol in ancient Greek and Egyptian cultures, as well as by the Aztecs, whose culture of human sacrifice was actually quite shocking. Even the Norse God Thor's hammer is thought to be represented by the Tau cross. And, even the Hebrew letter Tau (or Tav) is said to be a form of the cross. The writings of ninteenth century occultist Aleister Crowley teach that the cross and the Tau are at once symbols of power and the human phallus. Cross symbolism can be found in numerous civilizations, and cultures across a great many centuries.
