"On May-day the Druids made prodigious fires on these cairns, which being every one in sight of some other could not but afford a glorious show over a whole nation. These fires were in honor of Beal, or Bealan, Latinized by the Roman writers into Belanus, by which name the Gauls and their colonies understood the sun, and therefore, to this hour, the first of May is, by the aboriginal Irish, called la Bealtine, or the day of Belan's fires. May-day is likewise called la Bealtine by the Highlanders of Scotland, who are no contemptible part of the Celtic offspring. So it is with the Isle of Man: and in Armorica a priest is called Belee, or the servant of Bel, and the priesthood Belegieth."(136) 136) Quoted by Godfrey Higgins, Celtic Druids, ch. v., p. 181. Down to a comparatively recent time, in the British Isles, the youth of both sexes used to arise long before daybreak on May-day, and in large companies set out for the woods, there to gather flowers, boughs, and branches, which, on returning at night, were used to decorate their homes. This festival is said to be the most ancient of any known, and during the earlier and purer ages of human faith was celebrated in honor of returning spring. In later ages, however, after passion had become the only recognized god, May-day was celebrated with "all manner of obscenity and lewdness." Although the uneducated masses among the Gauls worshipped Apollo, Mercury, and Mars without understanding their true significance, the Druids, who are thought to be Pythagorians, invoked one great power, the animating force which pervades the universe, the essence of which they believed resides in fire. It is related that although after the introduction of Romish Christianity, May fires still continued to be lighted on Bealtine day, the more impressive ceremonies took place on the 23d of June, on the eve of the nativity of St. John. The early preachers, wishing to defer to the prejudices and usages of the people, "yet not so as to interfere with the celebration of Easter at the vernal equinox, retained the Bealtine ceremonial, only transferring it to the saint's day." Of these fire festivals and their adoption by the Christian church Tylor says: "The solar Christmas festival has its pendant at mid-summer. The summer solstice was the great season of fire festivals throughout Europe on the heights, of dancing round and leaping through the fires, of sending blazing fire-wheels to roll down from the hills into the valleys, in sign of the sun's descending course. These ancient rites attached themselves in Christendom to St. John's Eve. "It seems as though the same train of symbolism which had adapted the mid-winter festival to the Nativity, may have suggested the dedication of the mid-summer festival to John the Baptist, in clear allusion to his words 'He must increase but I must decrease.'
