It was while all seemed going so smoothly that the supreme crisis in the lives of both men took place—the event which has linked the names of Ambrose and Theodosius for evermore.
Thessalonica, the chief town of Macedonia, was a beautiful city, and its Governor, Count Botheric, a special friend of the Emperor, who constantly went to pay him a visit when wearied out with the cares of state, which pressed on him so heavily in Constantinople. The people were gay and light-hearted, loving shows and pageants of all sorts, but more especially the games of the circus. In order to celebrate the defeat of Maximus, Botheric had arranged a series of special displays, and in the chariot races most of the prizes were carried off by one man, who became the idol of the moment. Furious, therefore, was the indignation which ran through the city when, immediately after the festival was over, the charioteer was accused of some disgraceful crime, and being found guilty, was thrown into prison by Botheric. In a body the populace surged up to the house of the Governor and demanded his release. But Botheric was not the man to be turned from what he knew to be right by an excited crowd. He absolutely refused to give way, and told them that the man had deserved the punishment he had given him, and more too. Then the passion of the mob broke loose. They attacked the Governor's house and the houses of all who were in authority. The soldiers who were ordered out were too few to cope with their violence. In the struggle Botheric was killed, and many of his friends also, and their bodies subjected to every kind of insult that madness could suggest.
Theodosius was in Milan when the news reached him, and after a few moments of stony horror he was seized with such terrific passion that it almost seemed as if he would die of rage. At last he spoke; to those who stood around the voice sounded as the voice of a stranger.
'The crime was committed by the whole town,' he said, 'and the whole town shall suffer.' Then, and without giving himself time to change his mind, he sat down and wrote the order for a massacre to one of the few magistrates left alive.
His words were probably reported to Ambrose, and no doubt the bishop tried his best to calm the wrath of the emperor. But Theodosius was in no mood to be reasoned with. He declined to see his friend, and left Milan, shutting himself up in silence till the terrible tale of vengeance was told.
In obedience to his instructions, games, and especially chariot races, were announced to take place in the circus. We do not know if the mob had broken open the prison and released the charioteer in whose honour so much blood had been shed; but if so we may be sure that he was present, and was hailed with shouts of welcome. The circus was crowded from end to end—not a single seat was vacant. The eyes of the spectators were fixed on the line of chariots drawn up at the starting-point, and drivers and lookers-on awaited breathlessly the signal. In their absorption they never noticed that soldiers had drawn silently up and had surrounded them. A moment later, and a signal was indeed given, but it was the signal for one of the bloodiest massacres that ever shocked the ancient world. Probably the authorities who carried out the emperor's orders went further than he intended, even in the first passion of his anger. But of one thing we may be quite sure, and that is that remorse and shame filled his soul when the hideous story reached him. Not that he would confess it; to the public he would say he was justified in what he had done, but none the less he would have given all he had to undo his actions. He came back one night to Milan, and shut himself up again in his palace.
At the time of the emperor's return Ambrose happened to be staying with a friend in the country, for his health had suffered from his hard work, and also from this last blow, and his uncertainty how best to bring Theodosius to a sense of his crime. When he entered Milan once more, he waited, in the hope that the emperor might send for him, as he was used to do; but as no messenger arrived, the bishop understood that Theodosius refused to see him, and the only course open was to write a letter.
The occasion was not one for polite phrases, neither was Ambrose the man to use them. In the plainest words he set his guilt before Theodosius and besought him to repent. And as his sin had been public, his repentance must be public too. But this letter remained unanswered. Theodosius was resolved to brave the matter out, and next day, accompanied by his usual attendants, he went to the great church.
At the porch Ambrose met him, and refused to let him pass.
