All the more important church festivals are survivals of old rites to the sun. "How many times the Church has decanted the new wine of Christianity into the old bottles of heathendom." Yule-tide, the pagan Christmas, celebrated the sun's turning north, and the old midsummer holiday is still kept in Ireland and on the Continent as St. John's Day by the lighting of bonfires and a dance about them from east to west as the sun appears to move. The pagan Hallowe'en at the end of summer was a time of grief for the decline of the sun's glory, as well as a harvest festival of thanksgiving to him for having ripened the grain and fruit, as we formerly had husking-bees when the ears had been garnered, and now keep our own Thanksgiving by eating of our winter store in praise of God who gives us our increase. Pomona, the Roman goddess of fruit, lends us the harvest element of Hallowe'en; the Celtic day of "summer's end" was a time when spirits, mostly evil, were abroad; the gods whom Christ dethroned joined the ill-omened throng; the Church festivals of All Saints' and All Souls' coming at the same time of year--the first of November--contributed the idea of the return of the dead; and the Teutonic May Eve assemblage of witches brought its hags and their attendant beasts to help celebrate the night of October 31st. CHAPTER II THE CELTS: THEIR RELIGION AND FESTIVALS The first reference to Great Britain in European annals of which we know was the statement in the fifth century B. C. of the Greek historian Herodotus, that Ph[oe]nician sailors went to the British Isles for tin. He called them the "Tin Islands." The people with whom these sailors traded must have been Celts, for they were the first inhabitants of Britain who worked in metal instead of stone. The Druids were priests of the Celts centuries before Christ came. There is a tradition in Ireland that they first arrived there in 270 B. C., seven hundred years before St. Patrick. The account of them written by Julius Cæsar half a century before Christ speaks mainly of the Celts of Gaul, dividing them into two ruling classes who kept the people almost in a state of slavery; the knights, who waged war, and the Druids who had charge of worship and sacrifices, and were in addition physicians, historians, teachers, scientists, and judges. Cæsar says that this cult originated in Britain, and was transferred to Gaul. Gaul and Britain had one religion and one language, and might even have one king, so that what Cæsar wrote of Gallic Druids must have been true of British.
