(M57) Many more examples might perhaps be cited of the marvellous virtues which certain plants have been supposed to acquire at the summer solstice, but the foregoing instances may suffice to prove that the superstition is widely spread, deeply rooted, and therefore probably very ancient in Europe. Why should plants be thought to be endowed with these wonderful properties on the longest day more than on any other day of the year? It seems difficult or impossible to explain such a belief except on the supposition that in some mystic way the plants catch from the sun, then at the full height of his power and glory, some fleeting effluence of radiant light and heat, which invests them for a time with powers above the ordinary for the healing of diseases and the unmasking and baffling of all the evil things that threaten the life of man. That the supposition is not purely hypothetical will appear from a folk-tale, to be noticed later on, in which the magic bloom of the fern is directly derived from the sun at noon on Midsummer Day. And if the magic flowers of Midsummer Eve thus stand in direct relation to the sun, which many of them resemble in shape and colour, blooming in the meadows like little yellow suns fallen from the blue sky, does it not become probable that the bonfires kindled at the same time are the artificial, as the flowers are the natural, imitations of the great celestial fire then blazing in all its strength? At least analogy seems to favour the inference and so far to support Mannhardt’s theory, that the bonfires kindled at the popular festivals of Europe, especially at the summer solstice, are intended to reinforce the waning or waxing fires of the sun. Thus if in our enquiry into these fire-festivals the scales of judgment are loaded with the adverse theories of Mannhardt and Westermarck, we may say that the weight, light as it is, of the magic flowers of Midsummer Eve seems to incline the trembling balance back to the side of Mannhardt.
