(M87) Whatever may be thought of an historical kernel underlying a mythical husk in the legend of Balder, the details of the story suggest that it belongs to that class of myths which have been dramatized in ritual, or, to put it otherwise, which have been performed as magical ceremonies for the sake of producing those natural effects which they describe in figurative language. A myth is never so graphic and precise in its details as when it is, so to speak, the book of the words which are spoken and acted by the performers of the sacred rite. That the Norse story of Balder was a myth of this sort will become probable if we can prove that ceremonies resembling the incidents in the tale have been performed by Norsemen and other European peoples. Now the main incidents in the tale are two—first, the pulling of the mistletoe, and second, the death and burning of the god; and both of them may perhaps be found to have had their counterparts in yearly rites observed, whether separately or conjointly, by people in various parts of Europe. These rites will be described and discussed in the following chapters. We shall begin with the annual festivals of fire and shall reserve the pulling of the mistletoe for consideration later on. CHAPTER IV. THE FIRE-FESTIVALS OF EUROPE. § 1. The Lenten Fires. (M88) All over Europe the peasants have been accustomed from time immemorial to kindle bonfires on certain days of the year, and to dance round or leap over them. Customs of this kind can be traced back on historical evidence to the Middle Ages,(262) and their analogy to similar customs observed in antiquity goes with strong internal evidence to prove that their origin must be sought in a period long prior to the spread of Christianity. Indeed the earliest proof of their observance in Northern Europe is furnished by the attempts made by Christian synods in the eighth century to put them down as heathenish rites.(263) Not uncommonly effigies are burned in these fires, or a pretence is made of burning a living person in them; and there are grounds for believing that anciently human beings were actually burned on these occasions. A general survey of the customs in question will bring out the traces of human sacrifice, and will serve at the same time to throw light on their meaning.(264)
