With regard to the solar-wheel, a great deal of very interesting information has been collected by M. Gaidoz.[40] He points out that in the museums of France there are a good many monuments that represent the sun-wheel along with the thunderbolt as the symbol of Jupiter, that is to say, the old Gaulish solar-god identified with the Roman deity, Jupiter. Gaulish warriors wore a wheel on their helmets--a wheel was a favourite symbol as a personal ornament, or perhaps as an amulet. The wheel-window in a Gothic minster derives from the solar-wheel. [Illustration: _Fig. 41._--ALTAR TO THE SOLAR-GOD, NIMES.] When Constantine led his legions against Maxentius, he professed to have seen a sign in the heavens, and he believed it to be a token of Christ’s assistance. What he really saw was a mock-sun. He adopted and adapted the sign for his standards, and the _Labarum_ of Constantine became a common Christian symbol. That there was policy in his conduct we can hardly doubt; the symbol he set up gratified the Christians in his army on one side, and the Gauls on the other. To the former it was a sign compounded of the initial letters of Christ, to the latter it was the token of the favour of their solar deity. An addition Constantine certainly made to the six-rayed wheel, but it was not one that materially affected its character. Among the Sclavonic races in like manner the sun was worshipped, and worshipped with symbols precisely the same. [Illustration: _Fig. 42._--THE LABARUM.] The solar god of the Sclaves was Swanto Wit or Swato Wit, _i.e._, Holy Light. The sun was the chief god of the Sclaves, and as the cock crows before sunrise and announces the coming day, the cock was regarded as sacred to the god, and sacrificed to it. The worship of this god consisted in circular dances, called _kolos_, and the dance was taken to represent the revolution of the planets, the constellations, the seasons about the sun. An old writer says of the dances of Swanto Wit that they were celebrated annually on the feast of St. John the Baptist, that is, on Midsummer Day. “Benches are placed in a circle, and these are leaped over by those who take part in the rite. No one is allowed to be present dressed in red. The entire month that precedes St. John’s Day, the votaries are in an excited condition, and in carrying on their dances they fall a prey to nervous terrors.”[41] Another writer tells us that they swung about a fiery wheel in their dances, a symbol of the solar disc.[42]
