His great love for a recluse life induced him to build a monastery near his house at Ruspe, which he designed to place under the direction of his old friend, the Abbot Felix. But before the building could be completed, King Thrasimund ordered the banishment of the Catholic bishops to Sardinia. Accordingly, S. Fulgentius and other prelates, sixty in all, were carried into exile, and during their banishment they were provided yearly with provisions and money by the liberality of Symmachus, Bishop of Rome. A letter of this Pope to them is still extant, in which he encourages them, and comforts them. S. Fulgentius, during his retirement, composed several treatises for the confirmation of the faith of the orthodox in Africa. King Thrasimund, desirous of seeing him, sent for him, and appointed him lodgings in Carthage. The king drew up a set of ten objections to the Catholic faith, and required Fulgentius to answer them. The Saint immediately complied with his request, and his answer had such effect, that the king, when he sent him new objections, ordered that the answers should be read to himself alone. He then addressed to Thrasimund a confutation of Arianism, which we have under the title of "Three Books to King Thrasimund." The prince was pleased with the work, and granted him permission to reside at Carthage; till, upon repeated complaints from the Arian bishops, of the success of his preaching, which threatened, they said, the total conversion of the city to the faith in the Consubstantial, he was sent back to Sardinia, in 520. He was sent on board one stormy night, that he might be taken away without the knowledge of the people, but the wind being contrary, the vessel was driven into port again in the morning, and the news having spread that the bishop was about to be taken from them, the people crowded to say farewell, and he was enabled to go to a church, celebrate, and communicate all the faithful. Being ready to go on board when the wind shifted, he said to a Catholic, whom he saw weeping, "Grieve not, I shall shortly return, and the true faith of Christ will flourish again in this realm, with full liberty to profess it; but divulge not this secret to any." The event confirmed the truth of the prediction. Thrasimund died in 523, and was succeeded by Hilderic, who gave orders for the restoration of the orthodox bishops to their sees, and that liberty of worship should be accorded to the Catholics.
