All-hallow Eve is now, in our country towns, a time of careless frolic, and of great bonfires, which, I hear, are still kindled on the hill-tops in some places. We also find these fires in England, Scotland, and Ireland, and from their history we learn the meaning of our celebration. Some of you may know that the early inhabitants of Great Britain, Ireland, and parts of France were known as Celts, and that their religion was directed by strange priests called Druids. Three times in the year, on the first of May, for the sowing; at the solstice, June 21st, for the ripening and turn of the year; and on the eve of November 1st, for the harvesting, those mysterious priests of the Celts, the Druids, built fires on the hill-tops in France, Britain, and Ireland, in honor of the sun. At this last festival the Druids of all the region gathered in their white robes around the stone altar or cairn on the hill-top. Here stood an emblem of the sun, and on the cairn was a sacred fire, which had been kept burning through the year. The Druids formed about the fire, and, at a signal, quenched it, while deep silence rested on the mountains and valleys. Then the new fire gleamed on the cairn, the people in the valley raised a joyous shout, and from hill-top to hill-top other fires answered the sacred flame. On this night, all hearth-fires in the region had been put out, and they were kindled with brands from the sacred fire, which was believed to guard the households through the year. But the Druids disappeared from their sacred places, the cairns on the hill-tops became the monuments of a dead religion, and Christianity spread to the barbarous inhabitants of France and the British Islands. Yet the people still clung to their old customs, and felt much of the old awe for them. Still they built their fires on the first of May,--at the solstice in June,--and on the eve of November 1st. The church found that it could not all at once separate the people from their old ways, so it gradually turned these ways to its own use, and the harvest festival of the Druids became in the Catholic Calendar the Eve of All Saints, for that is the meaning of the name "All-hallow Eve." In the seventh century, the Pantheon, the ancient Roman temple of all the gods, was consecrated anew to the worship of the Virgin and of all holy martyrs.
