circumstantially.[47] Similarly in Christian times, the most venerated forms of religion were, from a very early period, called in to lend sanctity to the imprecation, by devices which gave additional solemnity to the awful ceremony. In this the natural tendency of the church to follow the traditional customs of the populations from which its members were drawn was reinforced by the example of the practices of Judaism. The “covenant between the pieces,” by which Yahveh confirmed his promises to Abram, and by which the Jews renewed their promises to him, was a sacrificial ceremony of the most impressive character, only to be used on occasions of supreme importance. As soon as a permanent place of worship was provided, the altar in the temple was resorted to by litigants in order that the oath might be taken in the presence of Yahveh himself; and so powerful was the impression of this upon the Christian mind that in the early ages of the church there was a popular superstition that an oath taken in a Jewish synagogue was more binding and more efficient than one taken elsewhere.[48] These beliefs developed into a great variety of formulas, which would reward an examination more detailed than that which I can give them here. In the middle of the sixth century, Pope Pelagius I. did not disdain to absolve himself from the charge of having been concerned in the troubles which drove his predecessor Vigilius into exile, by taking a disculpatory oath in the pulpit, holding over his head a crucifix and the gospels;[49] and in the eighth century a priest accused without witnesses to prove his guilt was enabled to absolve himself by placing the cross upon his head and declaring his innocence by the Everlasting God.[50] So, when the holy Gregory of Tours was accused of reproachful words truly spoken of Queen Fredegonda, a council of bishops decided that he should clear himself of the charge by oaths on three altars, after celebrating mass on each, which he duly performed, doubtless more to his corporeal than his spiritual benefit.[51] This plan of reduplicating oaths on different altars was an established practice among the Anglo-Saxons, who, in certain cases, allowed the plaintiff to substantiate his assertion by swearing in four churches, while the defendant could rebut the charge by taking an oath of negation in twelve.[52] Seven altars are similarly specified in the ancient Welsh laws in cases where a surety desired to deny his suretyship;[53] and, according to the _Fleta_, as late as the thirteenth century, a custom was current among merchants of proving the payment of a debt by swearing in nine churches, the abuse of which led to its abrogation.[54]
