(M13) The foregoing customs, observed in many different parts of the world, present at least a superficial resemblance to the modern European practices of leaping over fires and driving cattle through them; and we naturally ask whether it is not possible to discover a general explanation which will include them all. We have seen that two general theories have been proposed to account for the European practices; according to one theory the customs in question are sun-charms, according to the other they are purifications. Let us see how the two rival theories fit the other facts which we have just passed in review. To take the solar theory first, it is supported, first, by a statement that the fires at the Pongol festival in Southern India are intended to wake the sun-god or the fire-god from his sleep;(29) and, second, by the etymology which connects Soranus, the god of Soracte, with the sun.(30) But for reasons which have already been given, neither of these arguments carries much weight; and apart from them there appears to be nothing in the foregoing customs to suggest that they are sun-charms. Nay, some of the customs appear hardly reconcilable with such a view. For it is to be observed that the fire-walk is frequently practised in India and other tropical countries, where as a rule people would more naturally wish to abate than to increase the fierce heat of the sun. In Yucatan certainly the intention of kindling the bonfires cannot possibly have been to fan the solar flames, since one of the principal evils which the bonfires were designed to remedy was precisely the excessive heat of the sun, which had withered up the maize crops.(31) Thus the solar theory is not strongly supported by any of the facts which we are considering, and it is actually inconsistent with some of them.
