The existence of the crown is a fact constantly alluded to in the sixth century, by St. Gregory of Tours amongst others; and about the year 409 St. Paulinus of Nola knew of its preservation. He writes: “The thorns with which the Saviour was crowned, and the other relics of his Passion, recall to us the living remembrance of his presence.”
No written testimonies of an earlier date remain, but these appear to be fully sufficient, as they are the expression of an oral tradition well known to every one. As for the idea that such a relic as this could have been invented in those ages of conscience and of faith, it is wholly inadmissible.
The crown was not found with the cross and nails on Mount Calvary, nor is it probable that it was there buried with them, but that, when Joseph of Arimathea took down the body of Jesus from the cross, he would have preserved it apart. That no mention of this remains to us is easily accounted for by the silence and the exceeding precautions necessary so long as the persecutions by Jews and pagans continued. During this time the relics of the Passion which had been in the custody of the Blessed Virgin, or by her entrusted to others, could not, for reasons of safety, have been distributed to the various churches, but were honorably preserved in private dwellings, to be brought forth and publicly acknowledged when peace was granted to the church by the conversion of Constantine. Then it was that St. Helena sought with pious eagerness for every memorial that could be found of the Crucifixion, and distributed them chiefly among the churches of Jerusalem, Constantinople, and Rome.[5]
An apparent difficulty still remains, which obliges us to inquire into the nature and form of the sacred crown, with respect to which ancient authors differ from one another, some asserting that it was formed of reed (juncus palustris),
about which, however, there are no points of any great sharpness; while others maintain it to have been made from the branches of a shrub belonging to the genus Rhamnus, several species of which, especially the Zizyphus Spina Christi, or the thorn of Christ, are furnished with exceedingly long, hard, and sharply-pointed thorns, exactly similar to those venerated in several churches, but bearing no resemblance whatever to the holy crown at Paris, which is, in fact, of reed.
How is this diversity to be accounted for? Thanks to the learned researches of M. Rohault de Fleury,[6] it is fully explained. The crown at Paris is a circle formed of small reeds bound together, and from which only a small number of particles have been taken. The opening is large enough to encircle the head and to fall rather low over the brow. But this circle is only the support or foundation, so to speak, of the painful crown of our Lord. The branches of those thorns of which we have been speaking were twined alternately within and without, and twisted across in such a manner as to form of these sharp spines not only a circlet but a cap, as it were, of torture, which covered the Redeemer’s head.
The year 1241 added new treasures to those already acquired by St. Louis. These were also from Constantinople, and sent as expressions of the homage paid by the Emperor Baldwin to the “Most Christian King.” These relics were accompanied by a parchment document to establish their authenticity, and which especially designated three remarkable portions of the true cross: the first and largest, Crucem Sanctam; the second, Magnam
partem Crucis; and the third, which was smaller, and known as the Cross of Victory, because it had been borne before the armies of Constantine and his successors, Aliam crucem mediocrem quam Crucem Triumphalem veteres appellabant. With these was sent also the point of the lance which had pierced our Saviour’s side, and which, from the beginning of the seventh century, had been kept in the chapel of the Martyrion, raised by Constantine on Mount Calvary over the very place of the Crucifixion. Heraclius, fearing lest the lance should fall into the hands of the Persians, sent it to Constantinople, from which the greater part of it was later taken to Antioch, where the Crusaders found it in 1097, but the point had been retained in the former city, and was sent from thence to Paris.
It was also in the palace of the Bucoleon at Byzantium that were for a long period preserved a portion of the purple robe, the reed, and the sponge of the Passion. Baldwin I., by means of certain concessions made to the other crusading princes, obtained that the chapel in this palace should remain undisturbed, and thus secured for himself the greater part of its treasures, which were so largely drawn upon by his successor for the benefit of St. Louis and of France.
On their arrival the king immediately prepared to erect an edifice that should be as worthy as possible to receive relics so precious; nor were there wanting at that time great artists well able to furnish the design. The middle of the thirteenth century was perhaps the best and purest period of religious architecture. Churches and cathedrals then arose the majesty of whose beauty has never been surpassed or even equalled.
