Abstract principles, however, though freely admitted, were not yet powerful enough to eradicate traditional customs rooted deeply in the feelings and prejudices of the age. The three bodies of law just cited contradict their own admissions, in retaining with more or less completeness the most monstrous of negative proofs—the ordeal of battle—and the introduction of torture soon after exposed the accused to the chances of the negative system in its most atrocious form. Still these codes show a marked progress as relates to the kindred procedure of compurgation. The Partidas, promulgated about 1262, record the convictions of an enlightened ruler as to what should be law rather than the existing institutions of a people, and were not accepted as authoritative until the middle of the fourteenth century. The absence of compurgation in Spain, moreover, was a direct legacy from the Wisigothic code, transmitted in regular descent through the Fuero Juzgo.[207] The Assises de Jerusalem is a more precious relic of mediæval jurisprudence. Constructed as a code for the government of the Latin kingdoms of the East, in 1099, by order of Godfrey of Bouillon, it has reached us only in the form assumed about the period under consideration, and as it presents the combined experience of the warriors of many Western races, its silence on the subject of conjurators is not a little significant. The work of Beaumanoir, written in 1283, is not only the most perfect embodiment of the French jurisprudence of his time, but is peculiarly interesting as a landmark in the struggle between the waning power of feudalism and the Roman theories which gave intensity of purpose to the enlightened centralization aimed at by St. Louis: and Beaumanoir likewise passes in silence over the practice of compurgation, as though it were no longer an existing institution. All these legislators and lawyers had been preceded by the Emperor Frederic II., who, in 1231, promulgated his “Constitutiones Sicularum” for the government of his Neapolitan provinces. Frederic was Latin, and not Teutonic, both by education and predilection, and his system of jurisprudence is greatly in advance of all that had preceded it. That conjurators should find no place in his scheme of legal procedure is, therefore, only what might be expected. The collection of laws known as the _Êtablissements_ of St. Louis is by no means a complete code, but it is sufficiently copious to render the absence of all allusion to compurgation significant. In fact, the numerous references to the Digest show how strong was the desire to substitute the Roman for the customary law, and the efforts of the king to do away with all negative proofs of course included the one under consideration. The same may be said of the _Livres de Jostice et de Plet_ and the _Conseil_ of Pierre de Fontaines, two unofficial books of practice, which represent with tolerable fulness the procedures
