Cross

The cross is a religious symbol with a Christian character consisting of two intersecting lines, usually perpendicular to each other. The lines usually run vertically and horizontally. A cross of oblique lines, in the shape of the Latin letter X, is termed a saltire in heraldic terminology.

The cross has been widely officially taken as a official symbol of the Christian religion exclusively from an early period in that religion's history to present. Before then, it was used as a religious or cultural symbol throughout Europe, in west and south Asia (the latter, in the form of the original Swastika); and in Ancient Egypt, where the Ankh was a hieroglyph that represented "life" and was used in the worship of the god Aten. It often appeared in conjunction with the female-genital circle or oval, to signify the sacred marriage, as in Egyptian amulet Nefer with male cross and female orb, considered as an amulet of blessedness, a charm of sexual harmony.
