Long, long ago there was born to a Roman knight and his wife Maja a little boy called Virgilius. While he was still quite little, his father died, and the kinsmen, instead of being a help and protection to the child and his mother, robbed them of their lands and money, and the widow, fearing that they might take the boy’s life also, sent him away to Spain, that he might study in the great University of Toledo.

Virgilius was fond of books, and pored over them all day long. But one afternoon, when the boys were given a holiday, he took a long walk, and found himself in a place where he had never been before. In front of him was a cave, and, as no boy ever sees a cave without entering it, he went in. The cave was so deep that it seemed to Virgilius as if it must run far into the heart of the mountain, and he thought he would like to see if it came out anywhere on the other side. For some time he walked on in pitch darkness, but he went steadily on, and by-and-by a glimmer of light shot across the floor, and he heard a voice calling, ‘Virgilius! Virgilius!’

‘Who calls?’ he asked, stopping and looking round.

‘Virgilius!’ answered the voice, ‘do you mark upon the ground where you are standing a slide or bolt?’

‘I do,’ replied Virgilius.

‘Then,’ said the voice, ‘draw back that bolt, and set me free.’

‘But who are you?’ asked Virgilius, who never did anything in a hurry.

‘I am an evil spirit,’ said the voice, ‘shut up here till Doomsday, unless a man sets me free. If you will let me out I will give you some magic books, which will make you wiser than any other man.’

Now Virgilius loved wisdom, and was tempted by these promises, but again his prudence came to his aid, and he demanded that the books should be handed over to him first, and that he should be told how to use them. The evil spirit, unable to help itself, did as Virgilius bade him, and then the bolt was drawn back. Underneath was a small hole, and out of this the evil spirit gradually wriggled himself; but it took some time, for when at last he stood upon the ground he proved to be about three times as large as Virgilius himself, and coal black besides.

‘Why, you can’t have been as big as that when you were in the hole!’ cried Virgilius.

‘But I was!’ replied the spirit.

‘I don’t believe it!’ answered Virgilius.

‘Well, I’ll just get in and show you,’ said the spirit, and after turning and twisting, and curling himself up, then he lay neatly packed into the hole. Then Virgilius drew the bolt, and, picking the books up under his arm, he left the cave.

For the next few weeks Virgilius hardly ate or slept, so busy was he in learning the magic the books contained. But at the end of that time a messenger from his mother arrived in Toledo, begging him to come at once to Rome, as she had been ill, and could look after their affairs no longer.

Though sorry to leave Toledo, where he was much thought of as showing promise of great learning, Virgilius would willingly have set out at once, but there were many things he had first to see to. So he entrusted to the messenger four pack-horses laden with precious things, and a white palfrey on which she was to ride out every day. Then he set about his own preparations, and, followed by a large train of scholars, he at length started for Rome, from which he had been absent twelve years.

His mother welcomed him back with tears in her eyes, and his poor kinsmen pressed round him, but the rich ones kept away, for they feared that they would no longer be able to rob their kinsman as they had done for many years past. Of course, Virgilius paid no attention to this behaviour, though he noticed they looked with envy on the rich presents he bestowed on the poorer relations and on anyone who had been kind to his mother.

Soon after this had happened the season of tax-gathering came round, and everyone who owned land was bound to present himself before the emperor. Like the rest, Virgilius went to court, and demanded justice from the emperor against the men who had robbed him. But as these were kinsmen to the emperor he gained nothing, as the emperor told him he would think over the matter for the next four years, and then give judgment. This reply naturally did not satisfy Virgilius, and, turning on his heel, he went back to his own home, and, gathering in his harvest, he stored it up in his various houses.

When the enemies of Virgilius heard of this, they assembled together and laid siege to his castle. But Virgilius was a match for them. Coming forth from the castle so as to meet them face to face, he cast a spell over them of such power that they could not move, and then bade them defiance. After which he lifted the spell, and the invading army slunk back to Rome, and reported what Virgilius had said to the emperor.

Now the emperor was accustomed to have his lightest word obeyed, almost before it was uttered, and he hardly knew how to believe his ears. But he got together another army, and marched straight off to the castle. But directly they took up their position Virgilius girded them about with a great river, so that they could neither move hand nor foot, then, hailing the emperor, he offered him peace, and asked for his friendship. The emperor, however, was too angry to listen to anything, so Virgilius, whose patience was exhausted, feasted his own followers in the presence of the starving host, who could not stir hand or foot.

Things seemed getting desperate, when a magician arrived in the camp and offered to sell his services to the emperor. His proposals were gladly accepted, and in a moment the whole of the garrison sank down as if they were dead, and Virgilius himself had much ado to keep awake. He did not know how to fight the magician, but with a great effort struggled to open his Black Book, which told him what spells to use. In an instant all his foes seemed turned to stone, and where each man was there he stayed. Some were half way up the ladders, some had one foot over the wall, but wherever they might chance to be there every man remained, even the emperor and his sorcerer. All day they stayed there like flies upon the wall, but during the night Virgilius stole softly to the emperor, and offered him his freedom, as long as he would do him justice. The emperor, who by this time was thoroughly frightened, said he would agree to anything Virgilius desired. So Virgilius took off his spells, and, after feasting the army and bestowing on every man a gift, bade them return to Rome. And more than that, he built a square tower for the emperor, and in each corner all that was said in that quarter of the city might be heard, while if you stood in the centre every whisper throughout Rome would reach your ears.

Having settled his affairs with the emperor and his enemies, Virgilius had time to think of other things, and his first act was to fall in love! The lady’s name was Febilla, and her family was noble, and her face fairer than any in Rome, but she only mocked Virgilius, and was always playing tricks upon him. To this end, she bade him one day come to visit her in the tower where she lived, promising to let down a basket to draw him up as far as the roof. Virgilius was enchanted at this quite unexpected favour, and stepped with glee into the basket. It was drawn up very slowly, and by-and-by came altogether to a standstill, while from above rang the voice of Febilla crying, ‘Rogue of a sorcerer, there shalt thou hang!’ And there he hung over the market-place, which was soon thronged with people, who made fun of him till he was mad with rage. At last the emperor, hearing of his plight, commanded Febilla to release him, and Virgilius went home vowing vengeance.

The next morning every fire in Rome went out, and as there were no matches in those days this was a very serious matter. The emperor, guessing that this was the work of Virgilius, besought him to break the spell. Then Virgilius ordered a scaffold to be erected in the market-place, and Febilla to be brought clothed in a single white garment. And further, he bade every one to snatch fire from the maiden, and to suffer no neighbour to kindle it. And when the maiden appeared, clad in her white smock, flames of fire curled about her, and the Romans brought some torches, and some straw, and some shavings, and fires were kindled in Rome again.

For three days she stood there, till every hearth in Rome was alight, and then she was suffered to go where she would.

But the emperor was wroth at the vengeance of Virgilius, and threw him into prison, vowing that he should be put to death. And when everything was ready he was led out to the Viminal H............
