Ludwig Müller, in his elaborate treatise, gives it as his opinion that the Swastika had no connection with the Tau cross or with the _Crux ansata_, or with the fire wheel, or with arani, or agni, or with the mystic or alphabetic letters, nor with the so-called spokes of the solar wheel, nor the forked lightning, nor the hammer of Thor. He considers that the triskelion might throw light on its origin, as indicating perpetual whirling or circular movement, which, in certain parts of southern Asia as the emblem of Zeus, was assimilated to that of Baal, an inference which he draws from certain Asiatic coins of 400 B. C. Mr. R. P. Greg[46] opposes this theory and expresses the opinion that the Swastika is far older and wider spread as a symbol than the triskelion, as well as being a more purely Aryan symbol. Greg says that Ludwig Müller attaches quite too much importance to the sun in connection with the early Aryans, and lays too great stress upon the supposed relation of the Swastika as a solar symbol. The Aryans, he says, were a race not given to sun worship; and, while he may agree with Müller that the Swastika is an emblem of Zeus and Jupiter merely as the Supreme God, yet he believes that the origin of the Swastika had no reference to a movement of the sun through the heavens; and he prefers his own theory that it was a device suggested by the forked lightning as the chief weapon of the air god. Mr. Greg's paper is of great elaboration, and highly complicated. He devotes an entire page or plate (21) to a chart showing the older Aryan fire, water, and sun gods, according to the Brahmin or Buddhist system. The earliest was Dyaus, the bright sky or the air god; Adyti, the infinite expanse, mother of bright gods; Varuna, the covering of the shining firmament. Out of this trinity came another, Zeus, being the descendant of Dyaus, the sky god; Agni, the fire; Sulya, the sun, and Indra, the rain god. These in their turn formed the great Hindu trinity, Brahma, Vishnu, and Siva--creator, preserver, and destroyer; and, in his opinion, the Swastika was the symbol or ordinary device of Indra as well as of Zeus. He continues his table of descent from these gods, with their accompanying devices, to the sun, lightning, fire, and water, and makes almost a complete scheme of the mythology of that period, into which it is not possible to follow him. However, he declines to accept the theory of Max Müller of any difference of form or meaning between the Suavastika and the Swastika because the ends or arms turned to the right or to the left, and he thinks the two symbols to be substantially the same. He considers it to have been, in the first instance, exclusively of early Aryan origin and use, and that down to about 600 B. C. it was the emblem or symbol of the supreme Aryan god; that it so continued down through the various steps of descent (according to the chart mentioned) until it became the device and symbol of Brahma, and finally of Buddha.
