De Buck had only a few copies of his work printed, these being intended for the cardinals and prelates particularly interested in the question. As none were put on the market, it was rumored that de Buck's superiors had suppressed the publication of the book and that all the copies printed, save five or six, had been destroyed. This was untrue; no copy had been destroyed and his superiors had laid no blame upon the author. Then, in 1863, a decree was obtained from the Congregation of Rites, renewing an older decree, whereby it was declared that a vial of blood placed outside of a sepulchral niche in the catacombs was an unmistakable sign by which the tomb of a martyr might be known, and it was proclaimed that Victor de Buck's opinion was formally disapproved and condemned by Rome. This too was false, as Father De Buck had never intimated that the placing of the vial of blood did not indicate the resting-place of a martyr, when it could be proved that the vial contained genuine blood, such as was supposed by the decree of the congregation.
