I go on to note one or two more examples of real magic in the State religion; but they are hard to find. Pliny tells that even in his day people believed that a runaway slave who had not escaped out of the city might be arrested by a spell uttered by the Vestal virgins.[99] I take this to mean that any one who had lost his slave might get the Vestals to use the spell as a means of keeping the runaway within the city. The word for spell is here _precatio_, _i.e._ a prayer, not _carmen_, which is the usual word for a spell; and Pliny evidently thinks of it as addressed to some god. But no doubt it was originally at least a genuine spell, of the same kind as others used in private life, which we shall notice directly; and it implies a belief in some magical power inherent in the Vestals, of whom we are told that if they accidentally met a criminal being led to punishment they might secure his release.[100] As the spell in this case seems to be telepathic, _i.e._ an exercise of will-power projected from a distance, it may perhaps be paralleled with certain mystical powers exercised by women, especially when their husbands are at war, among some savage peoples;[101] but we have no information about it beyond the passage in Pliny, and further guessing would be useless. This last is a case of genuine magic, but it is outside the ritual of the State, though exercised by a State priesthood. Within that ritual there is one other very curious case of what must be classed as a magical process, and one that has accidentally become famous. At the Lupercalia on February 15, the two young men called Luperci, or, more strictly, belonging respectively as leaders to the two collegia of Luperci, girt themselves with the skins of the slaughtered victims, which were goats, and then ran round the base of the Palatine hill, striking at all the women who came near them or offered themselves to their blows, with strips of skin cut from the hides of these same victims. The object was to produce fertility; on this point our authorities are explicit.[102] Thus this particular feature of the whole extraordinary ritual of the Lupercalia is unmistakably within the region of magic rather than of religion. Some potency was believed to work in the act of striking, though apparently without a spoken spell or _carmen_, such as usually accompanies acts of this kind; and this part of the rite, grotesque though it was, was allowed to survive by the grave religious authorities who drew up the calendar of religious festivals. It was probably a superstition too deeply rooted in the minds of the people to admit of being excluded; and, strange to say, it survived, in outward form at least, until Rome had become cosmopolitan and even Christian. The Lupercalia has always been a puzzle to students of early religion, and as each new theory is advanced, this strange festival is seized on for fresh interpretation;[103] but for our present
