The Grecians also were doubtless addicted to the superstitious use of charms against animals, although there is good authority for the statement that the citizens of ancient Athens did not hesitate on occasion to accelerate the flight of “ominous creatures, as cats and the like,” by throwing stones or other handy missiles at them in the night, a method wholly mundane and natural.[478] And in this connection we may quote the opinion of the Rev. Father Pierre Le Brun, in his “Histoire critique des pratiques superstitieuses” (Amsterdam, 1733). The learned writer remarks that, if it were desired to drive a strange dog out of one’s room, it would be quite unsuitable to _begin_ with prayer and the use of holy water. One should rather first open the door and take hold of a stick, or throw some food outside; and if these and other practical measures fail, then recourse may be had to supernatural expedients, provided these have ecclesiastical sanction. In a treatise against superstition by a French _savant_, Martin of Arles, published in 1650, it was stated that the friars of the monastery of Ardennes were wont to boast that no rats could thrive in their neighborhood, and that this fact was due to the merits of St. Ulric, Bishop of Augsburg, some of whose relics were deposited in their church. In this monastery also it had been formerly customary to scatter crumbs of bread which had been blessed, in places infested by vermin, and the monks believed that this procedure either caused the death of the animals or frightened them away. Thuringian houses are sometimes cleared of rats in the following manner: Before sunrise on Good Friday morning, the master of the house, barefooted and in his shirt-sleeves, goes through every room blowing on a tiny whistle made out of the thigh bone of a rat’s hind leg.[479] Another curious method of expelling vermin from a dwelling is in vogue in some portions of the Austrian Empire. Before the dawn of a principal feast day, one must take an old shoe which has not been recently cleaned, and lay it on the ground at a place where two roads cross. No word must meanwhile be spoken aloud, but a _Paternoster_ is to be silently repeated. The direction in which the shoe points indicates the course to be taken by the rats in their flight.[480] In the village of Bechlin, a few miles north of Prague, troublesome mice are thus dealt with: Very early on an Easter Sunday morning, before the bells have rung for the first Mass, the peasant matron collects and fastens together all the house-keys. Then she waits until the first stroke of the bell for High Mass at noon, whereupon she proceeds to the cellar, meanwhile jingling the keys vigorously so long as the church-bells ring; when they cease she retraces her steps, still rattling the keys; and these measures are believed to permanently frighten away the mice.[481]
