The unlucky termination of Robert’s career did not affect his colleagues, and thenceforth the Inquisition was permanently established throughout France in Dominican hands. The prelates at first were stimulated to some show of rivalry in the performance of their neglected duties. Thus the provincial council of Tours, in 1239, endeavored to revive the forgotten system of synodal witnesses. Every bishop was instructed to appoint in each parish three clerks--or, if such could not be had, three laymen worthy of trust--who were to be sworn to reveal to the officials all ecclesiastical offences, especially those concerning the faith. Such devices, however, were too cumbrous and obsolete to be of any avail against a crime so sedulously and so easily concealed as heresy, even if the prelates had been zealous and earnest persecutors. The Dominicans remained undisputed masters of the field, always on the alert, travelling from place to place, scrutinizing and questioning, searching the truth and dragging it from unwilling hearts. Yet scarce a trace of their strenuous labors has been left to us. Heretics throughout the North were comparatively few and scattered; the chroniclers of the period take no note of their discovery and punishment, nor even of the establishment of the Inquisition itself. That a few friars should be deputed to the duty of hunting heretics was too unimpressive a fact to be worthy of record. We know, however, that the pious King Louis welcomed them in his old hereditary dominions, as he did in the newly-acquired territories of Languedoc, and stimulated their zeal by defraying their expenses. In the accounts of the royal baillis for 1248 we find entries of sums disbursed for them in Paris, Orleans, Issoudun, Senlis, Amiens, Tours, Yèvre-le-Chatel, Beaumont, St. Quentin, Laon, and Macon, showing that his liberality furnished them with means to do their work, not only in the domains of the crown, but in those of the great vassals; and these items further illustrate their activity in every corner of the land. That their sharp pursuit rendered heresy unsafe is seen in the permission already alluded to, in 1255, to pursue their quarry across the border into the territories of Alphonse of Toulouse, thus disregarding the limitations of inquisitorial districts.[129]
