The Itinerary of Archbishop Baldwin through Wales: Book 2 Chapter 2. We slept that night in the monastery of St. Dogmael [Map], where, as well as on the next day at Aberteivi [Map], we were handsomely entertained by [his father] prince Rhys [aged 55]. On the Cemmeis side of the river, not far from the bridge, the people of the neighbourhood being assembled together, and Rhys and his two sons, Malgon [aged 17] and [his brother] Gruffydd, being present, the word of the Lord was persuasively preached both by the archbishop and the archdeacon, and many were induced to take the cross; one of whom was an only son, and the sole comfort of his mother, far advanced in years, who, steadfastly gazing on him, as if inspired by the Deity, uttered these words:- "O, most beloved Lord Jesus Christ, I return thee hearty thanks for having conferred on me the blessing of bringing forth a son, whom thou mayest think worthy of thy service." Another woman at Aberteivi, of a very different way of thinking, held her husband fast by his cloak and girdle, and publicly and audaciously prevented him from going to the archbishop to take the cross; but, three nights afterwards, she heard a terrible voice, saying, "Thou hast taken away my servant from me, therefore what thou most lovest shall be taken away from thee." On her relating this vision to her husband, they were struck with mutual terror and amazement; and on falling asleep again, she unhappily overlaid her little boy, whom, with more affection than prudence, she had taken to bed with her. The husband, relating to the bishop of the diocese both the vision and its fatal prediction, took the cross, which his wife spontaneously sewed on her husband's arm.
