[The Feast of the Nativity of the Virgin may have replaced a pagan festival; the coincidence of the Midsummer festival with the summer solstice implies that the founders of the festival regulated their calendar by observation of the sun.]
It is no doubt possible that these illuminations and fireworks, like the assassinations, are merely the natural and spontaneous expressions of that overflowing joy with which the thought of the birth of the Virgin must fill every pious heart; but when we remember how often the Church has skilfully decanted the new wine of Christianity into the old bottles of heathendom, we may be allowed to conjecture that the ecclesiastical authorities adroitly timed the Nativity of the Virgin so as to coincide with an old pagan festival of that day, in which fire, noise, and uproar, if not broken heads and bloodshed, were conspicuous features. The penny trumpets blown on this occasion recall the like melodious instruments which figure so largely in the celebration of Befana (the Eve of Epiphany) at Rome.[565]
[On the other hand the Celts divided their year, not by the solstices, but by the beginning of summer (the first of May) and the beginning of winter (the first of November).]
From the foregoing survey we may infer that among the heathen forefathers of the European peoples the most popular and widespread fire-festival of the year was the great celebration of Midsummer Eve or Midsummer Day. The coincidence of the festival with the summer solstice can hardly be accidental. Rather we must suppose that our pagan ancestors purposely timed the ceremony of fire on earth to coincide with the arrival of the sun at the highest point of his course in the sky. If that was so, it follows that the old founders of the midsummer rites had observed the solstices or turning-points of the sun's apparent path in the sky, and that they accordingly regulated their festal calendar to some extent by astronomical considerations.
[The division seems to have been neither astronomical nor agricultural but pastoral, being determined by the times when cattle are driven to and from their summer pasture.]
