The ides of January fell three days later (Tuesday), and, according to custom, horse races were held in the Hippodrome, and the Emperor was present. Both the Blues and the Greens importuned the Emperor with loud prayers to show mercy to the two culprits who had been rescued by accident from the gallows. No answer was accorded, and at the twenty-second race the spectators were amazed to hear the unexpected exclamation, “Long live the humane Greens and Blues!” The cry announced that the two parties would act in concert to force the government to grant a pardon, and it is probable that their leaders had previously arranged to co-operate. When the races were over, the factions agreed on a watchword, nika, “conquer,” and the rising which followed was known as the Nika Revolt. The united factions were known for the time as the Green-Blues (Prasino-venetoi).
In the evening the mob of rioters assembled at the Praetorium and demanded from the Prefect of the City what he intended to do with the refugees in St. Laurentius. No answer was given, and the rioters broke into the prison, released the criminals who were confined in it, killed some of the officials, and set fire to the building, which was partly burned. Elated by success they rushed eastward to the Augusteum and committed graver acts of incendiarism. They fired the Chalke, the entrance of the Great Palace, and not only was this consumed, but the flames spread northward to the Senate-house and the church of St. Sophia. These buildings were burned down.99
On the following morning (Wednesday, January 14) the Emperor ordered the races to be renewed. But the Blues and Greens were not in the humour for witnessing races. They set on fire the buildings at the northern end of the Hippodrome, and the conflagration destroyed the neighbouring baths of Zeuxippus with the portico of the Augusteum. It is probable that on this occasion Justinian did not appear in the Kathisma, or face the multitudes who were now clamouring in the Hippodrome, no longer interceding for the lives of the two wretches who had escaped the hangman, but demanding that three unpopular ministers should be deprived of their offices. The demonstration was directed against Eudaemon, Prefect of the City, Tribonian the Quaestor, and John of Cappadocia, and the situation had become so serious that the Emperor decided to yield.100 Tryphon was appointed Prefect of the City, Basilides Quaestor, and Phocas, a man of the highest probity, was persuaded to undertake the office of Praetorian Prefect.
These concessions would probably have satisfied the factions and ended the trouble, like similar concessions in previous reigns, if the decision had depended solely on the leaders of the Blues and Greens. But the movement now wore an aspect totally different from that of the previous day. We saw how the city had been filled by throngs of miserable country folk from the provinces who had been ruined by the fiscal administration of the Praetorian Prefect and were naturally animated by bitter resentment against the Emperor and the government. It was inevitable that they should take part in the disturbances;101 it was at least a good opportunity to compass the fall of the detested Cappadocian; and the riot thus assured the character and proportions of a popular rising. But there were other forces in the background, forces which aimed not merely at a reform of the administration, but at a change in the dynasty. The policy of Justinian in seeking to make his power completely independent of the Senate and the Imperial Council had caused deep animosity in the senatorial class, and the disaffected senators seized the opportunity to direct the rising against the throne.102 We must attribute to the secret agitation of these men and their agents the fact that the removal of the obnoxious ministers, especially of John, failed to pacify the people.
The plan was to set on the throne one of the nephews of Anastasius, unfortunate victims of their kinship to an Emperor. For we must acquit them of any ambitious designs of their own. They had been well treated by Justin and Justinian, and their only desire was to live in peace. Pompeius and Hypatius were out of the reach of the insurgents; they and many other senators were with Justinian in the Palace. It was therefore decided to proclaim Probus Emperor, and the mob rushed to his house. But they did not find him, for, fearing what might happen, he had left the city. In their angry disappointment they burned his house.
It was assuredly high time for the Emperor to employ military force to restore order. But the Palace guards, the Scholarians and Excubitors, were unwilling to do anything to defend the throne. They had no feeling of personal devotion to Justinian, and they decided to do nothing and await events. Fortunately for Justinian there happened to be troops of a more irregular kind in the city, and two loyal and experienced commanders. Belisarius, who as Master of Soldiers in the East had been conducting the war against Persia, had recently been recalled, and he had in his service a considerable body of armed retainers, chiefly of Gothic103 race. Mundus, a general who had done good service in the defence of the Danube, was also in the capital with a force of Heruls. But all the soldiers on whom the Emperor could count can hardly have reached the number of 1500.
It was perhaps on Thursday (January 15)104 that Belisarius rode forth at the head of Goths and Heruls to suppress the revolution. There was a battle, possibly in the Augusteum; many were killed; but the soldiers were too few to win a decisive victory, and the attack only exasperated the people. The clergy, it may be noted, seem to have made some vain attempts to restore order.105
During the two following days there was desultory street fighting, and another series of conflagrations. On Friday the mob again set fire to the Praetorium, which had only been partly damaged, but there was a strong north wind which blew the flames away from the building. They also set fire to the baths of Alexander, and the same wind carried the conflagration to the neighbouring hospice of Eubulus and hence to the church of St. Irene and the hospice of Sampson. On Saturday there was a conflict between the soldiers and the insurgents in the street which led northward from Middle Street to the Basilica and the quarter of Chalkoprateia.106 It would appear that some of the mob had occupied the Octagon, a building close to the Basilica, and the soldiers set it on fire. The same fatal north wind was blowing, and the flames, wafted southwards, spread to the church of St. Theodore Sphoracius and to the palace of Lausus, which was consumed with all its treasures, and thence raged along Middle Street, in the direction of the Forum of Constantine, destroying the colonnades and the church of St. Aquilina.107 We can imagine how great must have been the alarm in the Palace, which was almost in a state of siege.108 Justinian could not trust his guards, and he had strong and not unjustified suspicions that many of the senators who surrounded him were traitors. Fearing their treachery, he ordered them all to leave the Palace on Saturday at nightfall,109 except a few like the Cappadocian, whose loyalty was certain or whose interests were bound up with his own. He particularly suspected Hypatius and Pompeius, and when they protested against deserting him, his suspicions only grew stronger, and he committed the blunder of dismissing them.
On Sunday morning (January 18) the Emperor made an effort in person to pacify the people. He appeared in the Kathisma of the Hippodrome with a copy of the gospels in his hands, and a large crowd assembled. He swore on the holy book that he would grant an amnesty without any reservations and comply with the demands of his subjects. But the great part of the crowd was bitterly hostile. They cried, “You are perjuring yourself,”110 and “You would keep this oath to us as you kept your oath to vitalian.” And there were shouts of “Long live Hypatius!” Meanwhile it had become known that the nephews of Anastasius had left the Palace. The people thronged to the house of Hypatius, and in spite of his own reluctance and the entreaties of his wife Maria, who cried that he was being taken to his death, carried him to the Forum of Constantine, where he was crowned with a golden chain wreathed like a diadem.
A council was then held by Hypatius and the senators who were supporting his cause.111 Here we can see clearly that the insurrection was guided and fomented by men of high position who were determined to overthrow Justinian. The question was debated whether the Palace should be attacked
