But the season at which these fire-festivals have been mostly generally held all over Europe is the summer solstice, that is Midsummer Eve (the twenty-third of June) or Midsummer Day (the twenty-fourth of June). A faint tinge of Christianity has been given to them by naming Midsummer Day after St. John the Baptist, but we cannot doubt that the celebration dates from a time long before the beginning of our era. The summer solstice, or Midsummer Day, is the great turning-point in the sun's career, when, after climbing higher and higher day by day in the sky, the luminary stops and thenceforth retraces his steps down the heavenly road. Such a moment could not but be regarded with anxiety by primitive man so soon as he began to observe and ponder the courses of the great lights across the celestial vault; and having still to learn his own powerlessness in face of the vast cyclic changes of nature, he may have fancied that he could help the sun in his seeming decline--could prop his failing steps and rekindle the sinking flame of the red lamp in his feeble hand. In some such thoughts as these the midsummer festivals of our European peasantry may perhaps have taken their rise. Whatever their origin, they have prevailed all over this quarter of the globe, from Ireland on the west to Russia on the east, and from Norway and Sweden on the north to Spain and Greece on the south.[395] According to a mediæval writer, the three great features of the midsummer celebration were the bonfires, the procession with torches round the fields, and the custom of rolling a wheel. He tells us that boys burned bones and filth of various kinds to make a foul smoke, and that the smoke drove away certain noxious dragons which at this time, excited by the summer heat, copulated in the air and poisoned the wells and rivers by dropping their seed into them; and he explains the custom of trundling a wheel to mean that the sun, having now reached the highest point in the ecliptic, begins thenceforward to descend.[396] [T. Kirchmeyer's description of the Midsummer Festival.] A good general account of the midsummer customs, together with some of the reasons popularly alleged for observing them, is given by Thomas Kirchmeyer, a writer of the sixteenth century, in his poem _The Popish Kingdome_:--
