A good example of such survivals is the curious ceremony of the _aquaelicium_, without doubt a genuine case of magical "rain-making"--one of the many inadequate and blundering attempts on the part of primitive man to obtain what he needs. Probably it may be classed under the head of "sympathetic magic," but the evidence as to what was done in the ceremony is not quite explicit enough to allow us to do this confidently.[87] It was, of course, not included in the religious calendar, as it would be only occasionally called for, and could not be fixed to a day; but there is clear evidence that it was sanctioned by the State, for the pontifices took part in it, and the magistrates without the _toga praetexta_, and the lictors carrying the fasces reversed.[88] A stone, which lay outside the walls near the Porta Capena, was brought into the city by the pontifices, so far as we can make out the details, and it has been conjectured that it was taken to an altar of Jupiter Elicius on the Aventine hard by, this cult-title of the god of the sky having possibly some relation to the technical name of the ceremony. What was done with the stone we unluckily do not know; but it has been reasonably conjectured that it was a hollow one, and that it was filled with water which was allowed to run over the edge, as a means of inducing the rain-god to suffer the heavens to overflow.[89] It was called _lapis manalis_; and the epithet here can have nothing to do with the Manes, as in the case of another _lapis manalis_, of which I shall have a word to say later on, but must mean "pouring" or "overflowing." One or two other fragments of evidence point in the same direction, and I think we may fairly conclude that the rite was originally one of sympathetic magic--that as the stone overflowed, so the sky would pour down rain. In my _Roman Festivals_ I have pointed out a remarkable parallel to this in the collections of the _Golden Bough_; in a Samoan village a stone represented the god of rain, and in a drought his priests carried it in procession and dipped it in a stream.
