The Cross or Crucifix, is the principal symbol of the Christian religion, remembering the Crucifixion of Jesus Christ and the redeeming benefits of his Passion and death. The cross is a sign both of Christ himself and of the faith of Christians.
The cross-shaped sign, represented in its simplest form by a crossing of two lines at right angles, greatly predates the introduction of Christianity, in both East and West. It goes back to a very remote period of human civilization. It is supposed to have been used not just for its ornamental value, but also with religious significance.
Another associated symbol is the ansated cross (ankh or crux ansata) used in ancient Egypt. It was often depicted in the hands of the goddess Sekhmet, and as a hieroglyphic sign of life or of the living. Egyptian Christians (Copts) adopted it as the emblem of the cross.
