But he had met his match at the outset. The blood of Theodora was not easily put down. The Consul laughed to scorn the pretensions of the young Pope; the nobles were in arms, the city was his, and in the second year of his Pontificate, Gregory the Fifth was driven ignominiously from the gates in a state of absolute destitution. He was the third Pope whom Crescenzio had driven out. Gregory made his way to Pavia, summoned a council of Bishops, and launched the Major Excommunication at his adversary. But the Consul, secure in Sant' Angelo, laughed again, more grimly, and did as he pleased.

At this time Basil and Constantine, joint Emperors in Constantinople, sent ambassadors to Rome to Otto the Third, and with them came a certain John, a Calabrian of Greek race, a man of pliant conscience, tortuous mind, and extraordinary astuteness, at that time Archbishop of Piacenza, and formerly employed by Otto upon a mission to Constantinople. Crescenzio, as though to show that his enmity was altogether against the Pope, and not in the least against the Emperor, received these envoys with great honour, and during their stay persuaded them to enter into a scheme which had suddenly presented itself to his ambitious intelligence. The old dream of restoring Rome to the Eastern Empire was revived, the conspirators resolved to bring it to realization, and John of Calabria was a convenient tool for their hands. He was to be Pope; Crescenzio was to be despot, under the nominal protection and sovereignty of the Greek Emperors, and the ambassadors were to conclude the treaty with the latter. Otto was on the German frontier waging war against the Slavs, and Gregory was definitely exiled from Rome. Nothing stood in the way of the plot, and it was forthwith put into execution. Certain ambassadors of Otto's were passing through Rome on their return from the East and on their way to the Emperor's presence; they were promptly seized and thrown into prison, in order to interrupt communication between the two Empires. John of Calabria was consecrated Pope, or rather antipope, Crescenzio took possession of all power, and certain legates of Pope Gregory having ventured to enter Rome were at once imprisoned with the Emperor's ambassadors. It was a daring stroke, and if it had succeeded, the history of Europe would have been different from that time forward. Crescenzio was bold, unscrupulous, pertinacious and keen. He had the Roman nobles at his back and he controlled such scanty revenues as could still be collected. He had violently expelled three Popes, he had created two antipopes, and his name was terror in the ears of the Church. Yet it would have taken more than all that to overset the Catholic Church at a time when the world was ripe for the first crusade; and though the Empire had fallen low since the days of Charles the Great, it was fast climbing again to the supremacy of power in which it culminated under Barbarossa and whence it fell with Frederick the Second. A handful of high-born murderers and marauders might work havoc in Rome for a time, but they could neither destroy that deep-rooted belief nor check the growth of that imperial law by which Europe emerged from the confusion of the dark age—to lose both law and belief again amid the intellectual excitements of the Renascence.

Otto the Third was young, brave and determined, and before the treaty with the Eastern Emperors was concluded, he was well informed of the outrageous deeds of the Roman patricians. No sooner had he brought the war on the Saxon frontier to a successful conclusion than he descended again into Italy 'to purge the Roman bilge,' in the chronicler's strong words. On his way, he found time to visit Venice secretly, with only six companions, and we are told how the Doge entertained him in private as Emperor, with sumptuous suppers, and allowed him to wander about Venice all day as a simple unknown traveller, with his companions, 'visiting the churches and the other rare things of the City,' whereby it is clear that in the year 998, when Rome was a half-deserted, half-ruined city, ruled by a handful of brigands living in the tomb of the Cæsars, Venice, under the good Doge Orseolo the Second, was already one of the beautiful cities of the world, as well as mistress of the Adriatic, of all Dalmatia, and of many lovely islands.

Otto took with him Pope Gregory, and with a very splendid army of Germans and Italians marched down to Rome. Neither Crescenzio nor his followers had believed that the young Emperor was in earnest; but when it was clear that he meant to do justice, Antipope John was afraid, and fled secretly by night, in disguise. Crescenzio, of sterner stuff, heaped up a vast provision of food in Sant' Angelo, and resolved to abide a siege. The stronghold was impregnable, so far as any one could know, for it had never been stormed in war or riot, and on its possession had depended the long impunity of Theodora's race. The Emperor might lay siege to it, encamp before it, and hem it in for months; in the end he must be called away by the more urgent wars of the Empire in the north, and Crescenzio, secure in his stronghold, would hold the power still. But when the Roman people knew that Otto was at hand and that the antipope had fled, their courage rose against the nobles, and they went out after John, and scoured the country till they caught him in his disguise, for his face was known to many. Because the Emperor was known to be kind of heart, and because it was remembered also that this John of Calabria, who went by many names, had by strange chance baptized both Otto and Pope Gregory, the Duke of Franconia's son, therefore the Romans feared lest justice should be too gentle; and having got the antipope into their hands, they dealt with him savagely, put out his eyes, cut out his tongue and sliced off his nose, and drove him to prison through the city, seated face backwards on an ass. And when the Emperor and the Pope came, they left him in his dungeon.

Now at Gaeta there lived a very holy man, who was Saint Nilus, and who afterwards founded the monastery of Grottaferrata, where there are beautiful wall paintings to this day. He was a Greek, like John of Calabria, and though he detested the antipope he had pity on the man and felt compassion for his countryman. So he journeyed to Rome and came before Otto and Gregory, who received him with perfect devotion, as a saint, and he asked of them that they should give him the wretched John, 'who,' he said, 'held both of you in his arms at the Font of Baptism,' though he was grievously fallen since that day by his great hypocrisy. Then the Emperor was filled with pity, and answered that the saint might have the antipope alive, if he himself would then remain in Rome and direct the monastery of Saint Anastasia of the Greeks. The holy man was willing to sacrifice his life of solitary meditation for the sake of his wretched countryman, and he would have obtained the fulfilment of his request from Otto; but Pope Gregory remembered how he himself had been driven out penniless and scantily clothed, to make way for John of Calabria, and his heart was hardened, and he would not let the prisoner go. Wherefore Saint Nilus foretold that because neither the Pope nor the Emperor would have mercy, the wrath of God should overtake them both. And indeed they were both cut off in the flower of their youth—Gregory within one year, and Otto not long afterwards.

Meanwhile they sent Nilus away and laid siege to the Castle of Sant' Angelo, where Crescenzio and his men had shut themselves up with a good store of food and arms. No one had ever taken that fortress, nor did any one believe that it could be stormed. But Pope and Emperor were young and brave and angry, and they had a great army, and the people of Rome were with them, every man. They used such engines as they had,—catapults, and battering-rams, and ladders; and yet Crescenzio laughed, for the stone walls were harder than the stone missiles, and higher than the tallest ladders, and so thick that fire could not heat them from without, nor battering-ram loosen a single block in a single course; and many assaults were repelled, and many a brave soldier fell writhing and broken into the deep ditch with his ladder upon him.

When the time of fate was fulfilled, the end came on a fair April morning; one ladder held its place till desperate armed hands had reached the rampart, and swift feet had sprung upon the edge, and one brave arm beat back the twenty that were there to defend; and then there were two, and three, and ten, and a score, and a hundred, and the great castle was taken at last. Nor do we know surely that it was ever taken again by force, even long afterwards in the days of artillery. But Crescenzio's hour had come, and the Emperor took him and the twelve chief nobles who were with him, and cut off their heads, one by one, in quick justice and without torture, and the heads were set up on spikes, and the headless bodies were hung out from the high crenellations of the ramparts. Thus ended Crescenzio, but not his house, nor the line of Theodora, nor died he unavenged.

CHURCH OF SANT' EUSTACHIO
From a print of the last century

It is said and believed that Pope Gregory perished by the hands of the Crescenzi, who lived in the little street behind the Church of Saint Eustace. As for Otto, he came to a worse end, though he was of a pious house, and laboured for the peace of his soul against the temptations of this evil world. For he was young, and the wife of Crescenzio was wonderfully fair, and her name was Stefania. She came weeping before him and mourning her lord, and was beautiful in her grief, and knew it, as many women do. And the young Emperor saw her, and pitied her, and loved her, and took her to his heart in sin, and though he repented daily, he daily fell again, while the woman offered up her body and her soul to be revenged for the fierce man she had loved. So it came to pass, at last, that she found her opportunity against him, and poured poison into his cup, and kissed him, and gave it to him with a very loving word. And he drank it and died, and the prophecy of the holy man, Nilus, was fulfilled upon him.
