, is rarely found on the sepulchres in the catacombs at Rome,—the most ancient Christian memorials; but, instead of it, a combination of the letters ΧΡ prevails, as the monogram for "Christ." Aringhi, in his Roma Subterranea (Romæ, 1651) says:
"Illud autem fatendum nobis est, nullatenus ante felicissima Constantini Magni ad fidem traducti tempora crucem publicæ populorum venerationi expositam fuisse."—Vol. ii. lib. vi. c. xiv. p. 546.
The following statement from Humphrey's Montfaucon (vol. x. part ii. book iii. cap. 1. p. 158.) is very clear as to the form of the cross:
"The cross, made with beams put together, had the shape of the Samaritan tau, says St. Jerome, whose words are these: 'In the oldest Hebrew letters, which the Samaritans now make use of, the last, which is tau, had the form of a cross.' This tau, like a cross, was like the Τ of the Greeks, according to Paulinus, who says that the shape of the cross is expressed by the Greek letter tau, which stands for three hundred. The cross of our Lord was something different from the letter tau; the beam that was fixed in the earth crossing that which was athwart it above, and made as it were a head by rising above it: such a cross we see in the medals of Constantine the Great, in this form,
, and such is it found described in the most ancient Christian monuments; this is the form of the cross which St. Jerome means, when he compares it to birds flying, to a man swimming, and to a man praying to God, with his arms extended."
The Greek church has retained both forms: the Latin Church, in its ignorance of the Greek language, has lost the more important symbol. These forms were probably invented by Constantine, who used them on his helmet, as crests were afterwards used in the ages of chivalry.

The difference between the manner in which the members of the Greek and those of the Latin Church used to sign themselves with the sign of the cross is this: both used the right hand, the thumb and first and second fingers open, and the third and fourth closed; both began at the forehead, and descended to the breast: but in crossing that vertical line by an horizontal one, from one shoulder to the other, the Greeks go from the right to the left, but the Latins from the left to the right. It is said, that in the Latin Church, up to the thirteenth century, the cross line was traced indifferently from either shoulder.
Whilst there is this difference between the Greek and Latin sign of the cross when made upon oneself, there is also a difference between the two when made upon others. The Latin Benediction is given with the thumb and the first two fingers open; the third and fourth fingers remaining closed. This arrangement of the the fingers is symbolical of the Trinity: the three open fingers signifying the three divine persons, and the two closed fingers being emblematic of the two natures of Christ.
