Upon other coins also, what is said to be meant for the pontifical apex occurs as a round ball surmounted by something very like a cross, in the hand of a female figure representing Rome; exactly as the so-called Coronation Orb is to be seen upon coins of later date in the hand of this or that Christian Emperor.
The evidence as a whole, however, favours the supposition that the Coronation Orb, instead of having been derived from the Apex of the Pagan priests and thus signifying the claim to priesthood or headship of the church so often made by monarchs, is a development of the round object, frequently unsurmounted by anything, so continually to be met with upon ancient coins of Rome in the hand of this or that God, Goddess, or Ruler.
This being the case, it is a matter of very
considerable importance that we should be quite sure what the round object in question used to signify, and should base our assurance upon the results of personal investigation rather than upon the assumption that the popular explanation is necessarily the correct one.
Though the round object in question was, as stated, in days of old often used as a symbol by itself, it was sometimes, and, as time rolled on, more and more frequently, surmounted by a small female figure with wings; which figure was a representation of Victory. This figure was, after the establishment of Christianity as the State Religion of the Roman Empire, gradually, and only gradually, supplanted by the figure of the cross.
Although several writers of note assume that the initiative in this direction was taken by Constantine himself, the first step seems to have been taken upon the death of Constantine, when a coin or medal was issued on which the deceased monarch is called a God and is represented as holding a round object surmounted by the so-called Monogram of Christ; a symbol continually referred to by Eusebius and other writers of the fourth century as a cross.
Later on an instance occurs of the Monogram surmounting a round object held by a female figure representing Rome. This is upon a coin issued by Nepotianus, a nephew of Constantine.
Passing on to the reign of Valentinianus II., we find that that Emperor issued a coin upon which a round object surmounted by a cross is to be seen in the hand of Victory herself. This would appear to have been the first instance in which what we should call a cross, supplanted the representation of Victory as a small female figure with wings, as a symbol surmounting the round object which we are considering.
A similar coin was issued by Theodosius I., surnamed the Great; the last of the Emperors of Rome whose rule extended throughout the whole of the Roman world.
The instances named are, it will be understood, the exceptions to the general rule during a considerable period. And upon many of the coins of the Emperors mentioned, as well as upon those of the intervening Emperors, the round object held by those rulers is surmounted by either a Victory or a Phœnix; usually by the former, but in several instances by the latter.
