The first of April is in Welsh called Calan Ebrill, and an April Fool a Ffwl Ebrill; the similarity of English and Welsh words may be said to typify the similarity of observance. The universality of this observance among Aryan peoples would certainly indicate an origin in a time preceding the dispersion of the human family over the world. The Druids, tradition says, celebrated the revival of Nature's powers in a festival which culminated on the first of April in the most hilarious foolery. The Roman Saturnalia or feast of fools perpetuated the rite, though the purpose of the Christian revelry may quite possibly have been to ridicule the Druidic ceremonies.
