in the New Testament the instrument of crucifixion, and hence used for the crucifixion of Christ itself (Eph. 2:16; Heb. 12:2; 1 Cor. 1:17, 18; Gal. 5:11; 6:12, 14; Phil. 3:18). The word is also used to denote any severe affliction or trial (Matt. 10:38; 16:24; Mark 8:34; 10:21).
The forms in which the cross is represented are these:
1. The crux simplex (I), a "single piece without transom."
2. The crux decussata (X), or St. Andrew's cross.
3. The crux commissa (T), or St. Anthony's cross.
4. The crux immissa (t), or Latin cross, which was the kind of cross on which our Saviour died. Above our Lord's head, on the projecting beam, was placed the "title." (See CRUCIFIXION.)
