If the men who were burned in wicker frames by the Druids represented the spirit of vegetation, the animals burned along with them must have had the same meaning. Amongst the animals burned by the Druids or in modern bonfires have been, as we saw, cattle, cats, foxes, and cocks; and all of these creatures are variously regarded by European peoples as embodiments of the corn-spirit.(763) I am not aware of any certain evidence that in Europe serpents have been regarded as representatives of the tree-spirit or corn-spirit;(764) as victims at the midsummer festival in Luchon they may have replaced animals which really had this representative character. When the meaning of the custom was forgotten, utility and humanity might unite in suggesting the substitution of noxious reptiles as victims in room of harmless and useful animals. Thus it appears that the sacrificial rites of the Celts of ancient Gaul can be traced in the popular festivals of modern Europe. Naturally it is in France, or rather in the wider area comprised within the limits of ancient Gaul, that these rites have left the clearest traces in the customs of burning giants of wicker-work and animals enclosed in wicker-work or baskets. These customs, it will have been remarked, are generally observed at or about midsummer. From this we may infer that the original rites of which these are the degenerate successors were solemnised at midsummer. This inference harmonises with the conclusion suggested by a general survey of European folk-custom, that the midsummer festival must on the whole have been the most widely diffused and the most solemn of all the yearly festivals celebrated by the primitive Aryans in Europe. And in its application to the Celts this general conclusion is corroborated by the more or less perfect vestiges of midsummer fire-festivals which we have found lingering in all those westernmost promontories and islands which are the last strongholds of the Celtic race in Europe—Britanny, Cornwall, Wales, the Isle of Man, Scotland, and Ireland. In Scotland, it is true, the chief Celtic fire-festivals certainly appear to have been held at Beltane (1st May) and Hallow E’en; but this was exceptional. To sum up: the combined evidence of ancient writers and of modern folk-custom points to the conclusion that amongst the Celts of Gaul an annual festival was celebrated at midsummer, at which living men, representing the tree-spirit or spirit of vegetation, were enclosed in wicker-frames and burned. The whole rite was designed as a charm to make the sun to shine and the crops to grow.
