The conditions under which resort was had to this mode of deciding litigation have been the subject of some discussion. It has been assumed that, in the early period, before the ferocious purity of the Barbarians had become adulterated under the influence of Roman civilization, it was used in all description of cases, at the option of the defendant, and was in itself a full and satisfactory proof, received on all hands as equal to any other.[137] The only indication that I have met with, among the races of Teutonic stock, tending to the support of such a conjecture, occurs in the Lombard code, where Rotharis, the earliest compiler of written laws, abolishes a previously existing privilege of denying under oath a crime after it had been confessed.[138] A much more powerful argument on the other side, however, is derivable from the earliest text of the Salic law, to which reference has already been made. In this, the formula shows clearly that conjurators were only employed in default of other testimony;[139] and what lends additional force to the conclusion is that this direction disappears in subsequent revisions of the law, wherein the influences of Christianity and of Roman civilization are fully apparent. No safe deductions, indeed, can be drawn from mere omissions to specify that the absence of witnesses was necessary, for these ancient codes are drawn up in the rudest manner, and regulations which might safely be presumed to be familiar to every one would not, in their curt and barbarous sentences, be repeated with the careful redundancy which marks our modern statutes. Thus there is a passage in the code of the Alamanni which declares in the most absolute form that if a man commits a murder and desires to deny it, he can clear himself with twelve conjurators.[140] This, by itself, would authorize the assumption that compurgation was allowed to override the clearest and most convincing testimony, yet it is merely a careless form of expression, for another section of the same code expressly provides that where a fact is proved by competent witnesses the defendant shall not have the privilege of producing compurgators.[141]
