Roger, Count of Calabria and Sicily, besieging the town of Capua, one named Sergius, a Greek by birth, to whom he had given the command of 200 men, having suffered himself to be bribed, formed the design of betraying him, and of delivering the army of the count to the Prince of Capua, during the night. It was on the 1st of March that he was to execute his intention. St. Bruno, who then dwelt in the Desert of Squilantia, appeared to Count Roger, and told him to fly to arms promptly, if he would not be oppressed by his enemies. The count starts from his sleep, commands his people to mount their horses and see what is going on in the camp. They met the men belonging to Sergius, with the Prince of Capua, who having perceived them retired promptly into the town; those of Count Roger took 162 of them, from whom they learned all the secret of the treason. Roger went, on the 29th of July following, to Squilantia, and having related to Bruno what had happened to him, the saint said to him, "It was not I who warned you; it was the angel of God, who is near princes in time of war." Thus Count Roger relates the affair himself, in a privilege granted to St. Bruno. A monk[413] named Fidus, a disciple of St. Euthymius, a celebrated abbot in Palestine, having been sent by Martyrius, the patriarch of Jerusalem, on an important mission concerning the affairs of the church, embarked at Joppa, and was shipwrecked the following night; he supported himself above water for some time by clinging to a piece of wood, which he found by chance. Then he invoked the help of St. Euthymius, who appeared to him walking on the sea, and who said to him, "Know that this voyage is not pleasing to God, and will be of no utility to the mother of the Churches, that is to say, to Jerusalem. Return to him who sent you, and tell him from me not to be uneasy at the separation of the schismatics--union will take place ere long; for you, you must go to my laurel grove, and you must build there a monastery." Having said this, he enveloped Fidus in his mantle, and Fidus found himself immediately at Jerusalem, and in his house, without knowing how he came there; he related it all to the Patriarch Martyrius, who remembered the prediction of St. Euthymius concerning the building in the laurel grove a monastery. Queen Margaret, in her memoirs, asserts that God protects the great in a particular manner, and that he lets them know, either in dreams or otherwise, what is to happen to them. "As Queen Catherine de Medicis, my mother," says she, "who the night before that unhappy day dreamt she saw the king, Henry II., my father, wounded in the eye, as it really happened; when she awoke she several times implored the king not to tilt that day.
