Naturally, indeed, different views can be held as to what the various forms of the cross betoken. Thus, for example, according to Burnouf, Schliemann, and others, the Svastika represents the "fire's cradle," i.e., the pith of the wood, from which in oldest times in the point of intersection of the two arms the fire was produced by whirling round an inserted stick. [276] On the other hand, according to the view most widespread at the present day, it simply symbolises the twirling movement when making the fire, and on this, too, rests its application as symbol of the sun's course. [277] Hochart considers the cross in the shape of the Greek Tau as the inserted stick (pramantha) of the Vedic priests. [278] Very likely, however, this form arose simply through the identity of sound between the Greek and Phoenician letter, the Greeks having interchanged the like-sounding foreign letter with their own Tau. That the cross generally speaking, however, is connected with the Fire Cult, and that both parts of the sign originally contained a reference to the pieces of wood (aranî) of which in most ancient times use was made to produce fire, has been placed beyond doubt by the investigations into the matter. This is confirmed inter alia by the use of the symbol in the worship of the Vestals, the Roman fire-priestesses. This is the explanation of the wide extent of the symbol of the cross. Not only among the peoples of antiquity and in Europe, but also in Asia among the Indians and Chinese, it is in use from ancient times. In America, too, among the Mexicans and Incas, it played a part in worship long before the arrival of Europeans. In the same way is explained the close association of that symbol with the priestly office and kingly dignity, which was itself often connected with that office; similarly the intimate relations between the sign of the cross and the Gods of Fertility, Vegetation, and Seasons. For all of these were, as representatives of the warmth of life and the soul's breath, in their deepest nature, Fire-Gods special aspects, closer characterisations and connections of that one divinity, of whom the oldest form known to us is in the Vedic Agni, and in whose service the priests of all peoples and times grew to their overwhelming strength. [279] Julius Firmicus Maternus was thus quite right when he declared that Mithras, whose followers bore the sign of the cross upon their foreheads and at their communion-meal had the cross, imprinted upon the holy loaf, before their eyes, was an ancient Fire-God. [280] But if the cross is the symbol of fire and also of the Mediator God, who brings earth and heaven into connection, then the reason can be found why Plato in the "Timæus" makes the World Soul in the form of a Chi, i.e., an oblique cross, stretched between heaven and earth. [281] Then, indeed, it is not strange that the Christians of the first century regarded as an inspiration of the devil Plato's doctrine of the mediatory office of
