In the fourth century, after miraculous powers ceased to attend the progress of Christianity, and a system of wonder-working was established, the Jews, who had long watched with jealousy the advance of their rivals, began to think that they could also become adepts in pious frauds. Next one party took to magical arts as weapons of superiority. A conference is said to have taken place in the presence of Constantine and the devout empress-mother Helena between the Jews and the Christians. Pope Sylvester had already triumphed in argument over his infatuated opponents, when the Jews had recourse to magic. A noted enchanter commanded an ox to be brought forward; he whispered into the ear of the animal, which instantly fell dead at the feet of Constantine. The Jews shouted in triumph, for it was the word _Ham-semphorash_, the ineffable name of God, at the sound of which the awestruck beast had expired. Sylvester, with some shrewdness, observed, "As he who whispered the name must be well acquainted with it, why does not he fall dead in like manner?" The Jews answered contemptuously, "Let us have no more verbal disputations; let us come to actions." "So be it," said Sylvester; "and if this comes to life again at the name of Christ, will ye believe?" They all assented. Sylvester then raised his eyes to heaven, and said with a loud voice, "If _He_ be the true God whom I preach, in the name of Christ arise, you ox, and stand on your feet." The ox sprang up and began to move and feed. The legend then adds that the whole assembly was baptised. JULIAN INCITING THE JEWS TO REBUILD THE TEMPLE. Sozomen says that, though Julian the Apostate hated and oppressed the Christians, he was benevolent to the Jews merely in order to spite the Christians. He commanded the Jews to rebuild their Temple at Jerusalem, and gave them money to do so. They entered on the undertaking without reflecting that according to their holy prophets it could not be accomplished. They sought the most skilful artisans, collected materials, cleared the ground, and entered so earnestly on the task that even the women carried heaps of earth and sold their ornaments towards defraying the expense. Yet when they cleared the ground an earthquake occurred, and stones were thrown up from the earth, wounding those near, and houses were thrown down. After the earthquake the workmen returned to the task; and instead of regarding the unexpected wonder as a manifest indication that God was opposed to the re-creation of the Temple, they were consumed by a fire which burst from the foundations. This fact is related by all the contemporaries, who agree that the fire burst out either from the foundations or from the bowels of the earth. A still more extraordinary prodigy occurred, for the sign of the cross appeared on the garments of the workmen. These crosses were disposed like stars, and appeared the work of art. Many were hence led to confess that Christ was God, and repented and were baptised.
