On another occasion after that an old pious nun who lived near Dubthach’s house asked Brigit to go and address the twenty-seven Leinster saints in one assembly. It was just then that Ibor the bishop recounted in the assembly a vision which he had seen the night before. ”I thought”, said he, “that I saw this night the Virgin Mary in my sleep, and a certain venerable cleric said to me: ‘This is Mary who will dwell among you’.” Just then the nun and Brigit came to the assembly. ”This is the Mary who was seen by me in a dream.” The people of the assembly rose up before her and went to converse with her. They blessed her. The assembly was held where now is Kildare, and there Ibor the bishop says to the brethren: “This site is open to heaven, and it will be the richest of all in the whole island; and today a girl, for whom it has been prepared by God, will come to us like Mary.” It happened thus.
