during the sixteenth and seventeenth centuries, let them consult the Jesuit Litterae annuae, passim. Another favourite means with the clergy of the older Church for bringing to naught the "power of the air," was found in great processions bearing statues, relics, and holy emblems through the streets. Yet even these were not always immediately effective. One at Liege, in the thirteenth century, thrice proved unsuccessful in bringing rain, when at last it was found that the image of the Virgin had been forgotten! A new procession was at once formed, the Salve Regina sung, and the rain came down in such torrents as to drive the devotees to shelter.(233) (233) John of Winterthur describes many such processions in Switzerland in the thirteenth century, and all the monkish chronicles speak of them. See also Rydberg, Magic of the Middle Ages, p. 74. In Catholic lands this custom remains to this day, and very important features in these processions are the statues and the reliquaries of patron saints. Some of these excel in bringing sunshine, others in bringing rain. The Cathedral of Chartres is so fortunate as to possess sundry relics of St. Taurin, especially potent against dry weather, and some of St. Piat, very nearly as infallible against wet weather. In certain regions a single saint gives protection alternately against wet and dry weather--as, for example, St. Godeberte at Noyon. Against storms St. Barbara is very generally considered the most powerful protectress; but, in the French diocese of Limoges, Notre Dame de Crocq has proved a most powerful rival, for when, a few years since, all the neighbouring parishes were ravaged by storms, not a hailstone fell in the canton which she protected. In the diocese of Tarbes, St. Exupere is especially invoked against hail, peasants flocking from all the surrounding country
