Such are the facts which the author of these researches has collected on the existence of ancient Germanic customs, or analogous usages, in the towns of Castile and Leon, dating from the twelfth century. He unhesitatingly concludes therefrom that these same customs existed in the sixth and seventh centuries among the Spanish Visigoths, and formed a part of their institutions.
It is inconvenient to prove that facts are not true, for it devolves on him who affirms them to prove that they are so; and, in such a case as this, when we speak of epochs separated by five or six centuries, and by such a revolution as the dispossession of a people and a foreign conquest, inductions are not sufficient. { 253} The _Forum judicum_ is absolutely silent upon the appointment of military leaders, and upon compurgation by juries; nay, more, this latter institution is incompatible with the arrangements of this code in reference to judges and the administration of justice. No other contemporary authority contradicts the _Forum judicum_. Must we, upon the authority of facts of much more recent date, and which refer to an entirely different state of civilization, refuse to believe proofs so direct, and testimonies so positive?
I am aware of all that may be said about the disorders of these times, the continual gaps in the laws, and the disposition of legislators to omit precisely those usages which were most simple and universal, as though they had no need to be consecrated or even indicated by formal enactment. It is, in fact, very possible that the practice of compurgation by juries was not completely unknown to the Visigoths; it recurs in all Germanic customs, and it may not have disappeared either entirely or all at once, even after the introduction of a code derived principally from the Roman laws. But it is impossible to believe, in spite of this code, that it continued to be the common law, the fundamental institution, the veritable judicial system of the nation.
It is more easy to explain, with likelihood, the existence of these practices among the Spanish Goths of the twelfth century, than to justify, without proofs, or rather in opposition to all evidence, the arbitrary supposition of their prevalence among the Visigoths of the seventh. Such institutions have in themselves something of spontaneity; they correspond to a certain degree of civilization, to a certain state of social institutions; we meet with them under forms more or less similar, but fundamentally analogous, not only among all the Germanic peoples, but also among nearly all those barbaric peoples which, scarcely issued from a nomadic life, begin to establish themselves on a new territory, after they have conquered it. Now, the destruction of the monarchy of the Visigoths by the Arabs suspended the course of the institutions which it had received two centuries before, broke off the councils of Toledo, crushed or greatly diminished the predominance of the clergy, and, in fine, put a stop to the civilization which had commenced, and gave to affairs an entirely new direction.
