He was said to have been something of an ascetic, wearing thin clothing year round. Aspirants came in numbers to place themselves under his rule, but he wished to secure also some of his relatives for the new monastery. For this purpose he set out with some monks for Munster, but on coming near his father's home he was seized with an apparently mortal illness. He fell into a trance from the ninth hour of the day to cock-crow, and while in this state received the first of the ecstatic visions which have made him famous in medieval literature. In this vision were revealed to him the state of man in sin, the beauty of virtue. He heard the angelic choirs singing "the saints shall go from virtue to virtue, the God of Gods will appear in Sion." An injunction was laid on him by the two angels who appeared to restore him to his body to become a more zealous labourer for the Lord. Three nights later, the ecstasy was renewed. He was taken to the heavens by three angels who contended six times with demons for his soul. He saw the fires of
hell, the strife of demons, and then heard the angel hosts sing in four choirs "Holy, holy, holy, Lord God of hosts." Among the spirits of those just made perfect he recognized Saints Meldan and
Beoan. They entertained him with much spiritual instruction concerning the duties of ecclesiastics and monks, the dreadful effects of pride and disobedience, and the heinousness of spiritual and internal sins. They also predicted famine and pestilence. As he returned through the fire the demon hurled a tortured sinner at him, burning him, and the angel of the Lord said to him, "Because thou didst receive the mantle of this man when dying in his sin the fire consuming him hath scarred thy body also." Fursey's body bore the mark from that day forward. Exactly twelve months later he received a third vision. This time, the angel remained with him a whole day, instructed him for his preaching, and prescribed for him twelve years of apostolic labour. This he faithfully fulfilled in Ireland, and then stripping himself of all earthly goods he retired for a time to a small island in the ocean. After some years he founded a monastery at Rathmat on the shore of
Lough Corrib which Colgan identifies as Killursa, in the
deanery of
Annadown. His brothers
Foillan and
Ultan then joined the community at Rathmat, but Fursey seems to have renounced the administration of the monastery and to have devoted himself to preaching throughout the land, frequently exorcising evil spirits. == Mission to East Anglia ==
