No explanation is given of the details of the process by which this appeal to fortune was made, and I know of no contemporary applications by which its formula can be investigated; but in the primitive Frisian laws there is described an ordeal of the lot, which may reasonably be assumed to show us one of the methods in use. When a man was killed in a chance-medley and the murderer remained unknown, the friends had a right to accuse seven of the participants in the brawl. Each of these defendants had then to take the oath of denial with twelve conjurators, after which they were admitted to the ordeal. Two pieces of twig, precisely similar, were taken, one of which was marked with a cross; they were then wrapped up separately in white wool and laid on the altar; prayers were recited, invoking God to reveal the innocence or guilt of the party, and the priest, or a sinless youth, took up one of the bundles. If it contained the marked fragment, the defendants were absolved; if the unmarked one, the guilty man was among them. Each one then took a similar piece of stick and made a private mark upon it; these were rolled up as before, placed on the altar, taken up one by one, and unwrapped, each man claiming his own. The one whose piece was left to the last was pronounced guilty, and was obliged to pay the wer-gild of the murder.[1123] Among the ancient Irish the lot or _crannchur_ was employed by mingling white and black stones, when if the accused drew a black one he was adjudged guilty.[1124] The various modes of ecclesiastical divination, so frequently used in the Middle Ages to obtain an insight into the future, sometimes assumed the shape of an appeal to Heaven to decide questions of the present or of the past.[1125] Thus, when three bishops, of Poitiers, Arras, and Autun, each claimed the holy relics of St. Liguaire, and human means were unavailing to reconcile their pretensions, the decision of the Supreme Power was resorted to, by placing under the altar-cloth three slips with their respective names inscribed, and after a becoming amount of prayer, on withdrawing one of them, the see of Poitiers was enriched with the precious remains by Divine favor.[1126] That such appeals to chance were regarded by the Church with disfavor is shown by Gratian, who argues that the Hebrew examples were not precedents to be observed under the New Law.[1127] Yet the second council of Barcelona in 599 had decreed that when an episcopal vacancy was to be filled two or three candidates should be chosen by the clergy and people, and from among these the metropolitan and his suffragans should select one by lot, after due fasting and prayer.[1128]
