On the Life of St. Martin

Martin has to do both with Angels and Devils.

It is also well known that angels were very often seen by him, so that they spoke in turns with him in set speech. As to the devil, Martin held him so visible and ever under the power of his eyes, that whether he kept himself in his proper form, or changed himself into different shapes of spiritual wickedness, he was perceived by Martin, under whatever guise he appeared. The devil knew well that he could not escape discovery, and therefore frequently heaped insults upon Martin, being unable to beguile him by trickery. On one occasion the devil, holding in his hand the bloody horn of an ox, rushed into Martin's cell with great noise, and holding out to him his bloody right hand, while at the same time he exulted in the crime he had committed, said: “Where, O Martin, is your power? I have just slain one of your people.” Then Martin assembled the brethren, and related to them what the devil had disclosed, while he ordered them carefully to search the several cells in order to discover who had been visited with this calamity. They report that no one of the monks was missing, but that one peasant, hired by them, had gone to the forest to bring home wood in his wagon. Upon hearing this, Martin instructs some of them to go and meet him. On their doing so, the man was found almost dead at no great distance from the monastery. Nevertheless, although just drawing his last breath, he made known to the brethren the cause of his wound and death. He said that, while he was drawing tighter the thongs which had got loose on the oxen yoked together, one of the oxen, throwing his head free, had wounded him with his horn in the groin. And not long after the man expired. You see with what judgment of the Lord this power was given to the devil. This was a marvelous feature in Martin that not only on this occasion to which I have specially referred, but on many occasions of the same kind, in fact as often as such things occurred, he perceived them long beforehand, and disclosed the things which had been revealed to him to the brethren.
