interpreting as applicable to the Christian clergy the texts in the Old Testament bearing on the Levites; Gallican councils had repeatedly proclaimed it as an obligation, though, it appears, with little success. But from the reign of Pippin the Short onwards the civil law recognized and sanctioned this obligation, and the capitularies of Charlemagne and Louis the Debonnaire contain numerous provisions dealing with it. Ecclesiastical jurisdiction extended farther and farther, but Charlemagne, the protector of the papacy, maintained firmly his authority over the Church. He nominated its dignitaries, both bishops and abbots, who were true ecclesiastical officials, parallel with the lay officials. In each _pagus_, bishop and count owed each other mutual support, and the missi on the same circuit were ordinarily a count and a bishop. In the first collection of capitularies, that of Ansegisus, two books out of four are devoted to ecclesiastical capitularies. The law under the Frank monarchy. What, then, was the private and criminal law of this Frankish monarchy which had come to embrace so many different races? The men of Roman descent continued under the Roman law, and the conquerors could not hope to impose their customs upon them. The authorized expression of the Roman law was henceforth to be found in the _Lex romana Wisigothorum_ or _Breviarium Alarici_, drawn up by order of Alaric II. in 506. It is an abridgment of the codes, of that of Theodosius especially, and of certain of the writings of the jurists included under the Law of Citations. As to the barbarians, they had hitherto had nothing but customs, and these customs, of which the type nearest to the original is to be found in the oldest text of the _Lex Salica_, were nothing more than a series of tariffs of compensations, that is to say, sums of money due to the injured party or his family in case of crimes committed against individuals, for which crimes these compensations were the only penalty. They also introduced a barbarous system of trial, that by compurgation, i.e. exculpation by the oath of the defendant supported by a certain number of _cojurantes_, and that by ordeal, later called _judicium Dei_. In each new kingdom the barbarians naturally kept their own laws, and when these men of different races all became subject to the Frankish monarchy, there evolved itself a system (called the _personnalite des lois_) by which every subject had, in principle, the right to be tried by the law of the race to which he belonged by birth (or sometimes for some other reason, such as emancipation or marriage). When the two adversaries were of different race, it was the law of the defendant which had to be applied. The customs of the barbarians had been drawn up in Latin. Sometimes, as in the case of the first text of the Salic law, the system on which they were compiled is not exactly known; but it was generally done under the royal authority. At this
