During the remainder of the century, the statutes of many of the Italian cities show the gradual introduction of torture to replace the barbarian processes which were not indigenous,[1542] and which the traditional hate of the Italian States for the Tedeschi was not likely to render popular. That by the middle of the century, indeed, the practical applications of torture had been profoundly studied and were thoroughly understood in all their most inhuman ramifications is sufficiently evident from the accounts which we possess of the fearful cruelties habitually practised by petty despots such as Eccelino da Romano.[1543] The manner in which the use of torture thus in time was superimposed upon the existing customs of Europe is clearly shown in the law of Lubeck. The mercantile law of the Middle Ages disregarded, as we have seen, all the irregular forms of evidence, such as the ordeal, the judicial duel, &c., and it naturally was not favorable to torture. As the chief of the Hanse-towns Lubeck, therefore, in its legislation preserved the principles of the mercantile law, but in time these came to be expounded by a race of lawyers imbued with the ideas of the imperial jurisprudence, and little was left of the primitive simplicity of the original code. Thus the latter, when treating of adultery, simply provides that the accused must clear himself by oath, or be held guilty of the charge; but a commentary on it, written in 1664, assumes that as the crime is a peculiarly secret one recourse must be at once had to torture where there is colorable ground for suspicion.[1544]
