Two hundred years after the death of Virgil, his poems were laid up in the temple at Prœneste, for consultations. Alexander Severus sought the oracle in the reign of Heliogabalus, who feared and hated him; and the line of Virgil he read told him that “if he could surmount opposing fates, he would be Marcellus.” The Emperor Heraclius, when deliberating where to fix his winter quarters, was determined by an oracle of this sort. He purified his army during three days, and then opened the Gospels. The passage he found was understood by him to indicate that he should winter in Albania. Nicephorus Gregoras relates how Andronicus the Elder was reconciled to his nephew Andronicus in consequence of lighting on the verse of the Psalm (lxviii. 14), “When the Almighty scattered kings for their sake, then were they as white as snow in Salmon.” Whereby he concluded that all the troubles that had been undergone by him had been decreed by God for his purification. With the same intent during the consecration of a bishop, at the moment when the book of the Gospels was placed on his head, it was customary to open the volume and gather from the verse at the head of the page an augury of the prelate’s reign. This is illustrated in a curious ancient painting of the consecration of St. Thomas à Becket by Van Eyck, shown in the Leeds Fine Art Exhibition of 1868. Chroniclers and biographers have not failed to mention several prognostications given in this manner which were verified in the event. At the consecration of Athanasius, nominated to the patriarchate of Constantinople by Constantine Porphyrogenitus, a patriarchate which he stained with his crimes, “Caracalla, bishop of Nicomedia, having brought the Gospel,” says the historian Pachymerus, “the congregation prepared to take note of the oracle which would be manifest on the opening of the book, though this oracle is not infallibly true. The bishop of Nicæa, noticing that he had lighted on the words, ‘Prepared for the devil and his angels,’ groaned in the depth of his heart, and putting up his hand to hide the words, turned over the leaves of the book, and disclosed the other words, ‘The birds of the air come, and lodge in the branches’: words which seemed far removed from the ceremony which was being celebrated. All that could be done to hide these oracles was done, but it was found impossible to conceal the truth. It was said that they did not forbid the consecration, but that, nevertheless, they were not the effect of chance, for there is no such a thing as chance in the celebration of the Sacred Mysteries.”
