A cross is a compound geometrical figure 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 recognized as a symbol of Christianity from an early period in that religion's history.[1][2][3] Before then, it was used as a religious or cultural symbol throughout Europe, in western and south Asia (the latter, in the form of the original Swastika); and in Egypt, where the Ankh was a hieroglyph that represented "life" and was used in the worship of the god Aten. The effigy of a man hanging on a cross was set up in the fields to protect the crops.[citation needed] It often appeared in conjunction with the female-genital circle or oval, to signify the sacred marriage, as in Egyptian amulet Nefer[4] with male cross and female orb, considered as an amulet of blessedness, a charm of sexual harmony.[5]
The cross is a symbol most clearly associated with Christianity.
