Meanwhile Hildebrand secretly sent swift riders to Apulia, calling on Robert Guiscard for help, and still the nobles were faithful to him, and though Henry held the bridges, they were strong in Trastevere and the Borgo, which is the region between the Castle of Sant' Angelo and Saint Peter's. So it turned out that when Henry tried to bring his Antipope in solemn procession to enthrone him in the Pontifical chair, on Easter day, he found mailed knights and footmen waiting for him, and had to fight his way to the Vatican, and forty of his men were killed and wounded in the fray, while the armed nobles lost not one. Yet he reached the Vatican at last, and there he was crowned by the false Pope he had made, with the crown of the Holy Roman Empire. The chronicler apologizes for calling him an emperor at all. Then he set to work to destroy the dwellings of the faithful nobles, and laid siege to the wonderful Septizonium of Severus, in which the true Pope's nephew had fortified himself, and began to batter it down with catapults and battering-rams. Presently came the message of vengeance, brought by one man outriding a host, while the rabble were still building a great wall to encircle Sant' Angelo and starve Hildebrand to death or submission, working day and night like madmen, tearing down everything at hand to pile the great stones one upon another. Swiftly came the terrible Norman from the south, with his six thousand horse, Normans and Saracens, and thirty thousand foot, forcing his march and hungry for the Emperor. But Henry fled, making pretext of great affairs in Lombardy, promising great and wonderful gifts to the Roman rabble, and entrusting to their care his imperial city.
Like a destroying whirlwind of fire and steel Robert swept on to the gates and into Rome, burning and slaying as he rode, and sparing neither man, nor woman, nor child, till the red blood ran in rivers between walls of yellow flame. And he took Hildebrand from Sant' Angelo, and brought him back to the Lateran through the reeking ruins of the city in grim and fearful triumph of carnage and destruction.
That was the end of the Roman Forum, and afterwards, when the blood-soaked ashes and heaps of red-hot rubbish had sunk down and hardened to a level surface, the place where the shepherd fathers of Alba Longa had pastured their flocks was called the Campo Vaccino, the Cattle Field, because it was turned into the market for beeves, and rows of trees were planted, and on one side there was a walk where ropes were made, even to our own time.
It became also the fighting ground of the Regions. Among the strangest scenes in the story of the city are those regular encounters between the Regions of Monti and Trastevere which for centuries took place on feast days, by appointment, on the site of the Forum, or occasionally on the wide ground before the Baths of Diocletian. They were battles fought with stones, and far from bloodless. Monti was traditionally of the Imperial or Ghibelline party; Trastevere was Guelph and for the Popes. The enmity was natural and lasting, on a small scale, as it was throughout Italy. The challenge to the fray was regularly sent out by young boys as messengers, and the place and hour were named and the word passed in secret from mouth to mouth. It was even determined by agreement whether the stones were to be thrown by hand or whether the more deadly sling was to be used.
At the appointed time, the combatants appear in the arena, sometimes as many as a hundred on a side, and the tournament begins, as in Homeric times, with taunts and abuse, which presently end in skirmishes between the boys who have come to look on. Scouts are placed at distant points to cry 'Fire' at the approach of the dreaded Bargello and his men, who are the only representatives of order in the city and not, indeed, anxious to face two hundred infuriated slingers for the sake of making peace.
One boy throws a stone and runs away, followed by the rest, all prudently retiring to a safe distance. The real combatants wrap their long cloaks about their left arms, as the old Romans used their togas on the same ground, to shield their heads from the blows; a sling whirls half a dozen times like lightning, and a smooth round stone flies like a bullet straight at an enemy's face, followed by a hundred more in a deadly hail, thick and fast. Men fall, blood flows, short deep curses ring through the sunny air, the fighters creep up to one another, dodging behind trees and broken ruins, till they are at cruelly short range; faster and faster fly the stones, and scores are lying prostrate, bleeding, groaning and cursing. Strength, courage, fierce endurance and luck have it at last, as in every battle. Down goes the leader of Trastevere, half dead, with an eye gone, down goes the next man to him, his teeth broken under his torn lips, down half a dozen more, dead or wounded, and the day is lost. Trastevere flies towards the bridge, pursued by Monti with hoots and yells and catcalls, and the thousands who have seen the fight go howling after them, women and children screaming, dogs racing and barking and biting at their heels. And far behind on the deserted Campo Vaccino, as the sun goes down, women weep and frightened children sob beside the young dead. But the next feast day would come, and a counter-victory and vengeance.
That has always been the temper of the Romans; but few know how fiercely it used to show itself in those days. It would have been natural enough that men should meet in sudden anger and kill each other with such weapons as they chanced to have or could pick up, clubs, knives, stones, anything, when fighting was half the life of every grown man. It is harder to understand the murderous stone throwing by agreement and appointment. In principle, indeed, it approached the tournament, and the combat of champions representing two parties is an expression of the ancient instinct of the Latin peoples; so the Horatii and Curiatii fought for Rome and Alba—so Francis the First of France offered to fight the Emperor Charles the Fifth for settlement of all quarrels between the Kingdom and the Empire—and so the modern Frenchman and Italian are accustomed to settle their differences by an appeal to what they still call 'arms,' for the sake of what modern society is pleased to dignify by the name of 'honour.'
But in the stone-throwing combats of Campo Vaccino there was something else. The games of the circus and the bloody shows of the amphitheatre were not forgotten. As will be seen hereafter, bull-fighting was a favourite sport in Rome as it is in Spain today, and the hand-to-hand fights between champions of the Regions were as much more exciting and delightful to the crowd as the blood of men is of more price than the blood of beasts.
The habit of fighting for its own sake, with dangerous weapons, made the Roman rabble terrible when the fray turned quite to earnest; the deadly hail of stones, well aimed by sling and hand, was familiar to every Roman from his childhood, and the sight of naked steel at arm's length inspired no sudden, keen and unaccustomed terror, when men had little but life to lose and set small value on that, throwing it into the balance for a word, rising in arms for a name, doing deeds of blood and flame for a handful of gold or a day of power.
Monti was both the battlefield of the Regions and also, in times early and late, the scene of the most splendid pageants of Church and State. There is a strange passage in the writings of Ammianus Marcellinus, a pagan Roman of Greek birth, contemporary with Pope Damasus in the latter part of the fourth century. Muratori quotes it, as showing what the Bishopric of Rome meant even in those days. It is worth reading, for a heathen's view of things under Valens and Valentinian, before the coming of the Huns and the breaking up of the Roman Empire, and, indeed, before the official disestablishment, as we should say, of the heathen religion; while the High Priest of Jupiter still offered sacrifices on the Capitol, and the six Vestal Virgins still guarded the Seven Holy Things of Rome, and held their vast lands and dwelt in their splendid palace in all freedom of high privilege, as of old.
