The adornment of rings with religious emblems, and their use as insignia of office for the higher ecclesiastics and for the priests of the ancient ethnic religions will be considered in the present chapter. Of special interest are the rings used by Roman Catholic popes, cardinals and bishops, the usage in this direction having varied considerably in the different periods. With regard to the engravings on many ancient rings it may often be difficult, however, to know whether a religious symbol, or the conventional figure of a divinity, has been used in a strictly religious sense, or merely for ornamental purposes. The employment of rings as religious symbols is often bound up with their use in some other way, as in the case of many seal rings for instance. This was undoubtedly the case with a large number of the ancient rings noted in earlier chapters. Here we have endeavored to group together those which were more exclusively religious in their character, the ecclesiastical rings, especially those worn by Roman Catholic popes, cardinals and bishops, constituting of course a large part of these. A very few examples will serve as brief illustrations of the religious use of rings in pagan times. There is in the Louvre, among the Egyptian antiquities, a gold ring engraved with figures of two horses. The symbol of the Sun-God which it bears is believed to signify the gratitude of Rameses II--to whom this ring is attributed--for the aid of the divinity in securing the king’s victory over the Khetas in one of his Asiatic campaigns. Unquestionably many of the engraved scarabs set in Egyptian rings had a specifically religious significance, and the same is true of the engravings on the chatons of gold rings, as, for example, in the case of that worn by the priest in charge of the Pyramid of Cheops (Khufu). Some of these have already been described in the chapter on signets, the essential use of these rings being for sealing. In many other cases the presence of a divine name as a component of the royal name, or in a royal title, probably had not much more of a distinctly religious meaning than the “Dei Gratia” on the coins of European rulers. The rings worn by the high priests of Jupiter (flamines Diales), who had, ex-officio, the rank of senators, were made hollow and of openwork. This particular form is said to have been chosen for mystic and symbolic reasons, as showing that everything indicating hardness or severity, the restriction of liberty, or arduous labor, was to be held aloof from this flamen, who, with those of Mars and Quirinus (Romulus), belonged to the group of greater priests selected from the patrician order.[399] The conjecture that we should seek here the origin of Christian episcopal rings is very far-fetched, the general symbolism of the ring as an emblem of eternity, and its bestowal as a mark of rank, having been probably sufficient determining factors.
