his Colca residing one time in the Iouan island (Hy, now Iona) with the saint, was asked by him concerning his mother whether she was a pious woman or not. Colca answered him, "I have always known my mother to be good, and to bear that character." The saint then spoke these prophetic words: "Set out now at once for Scotia (Ireland), with God's help, and question thy mother closely regarding her very grievous secret sin, which she will not confess to any man." To carry out the advice thus given him he departed to Hibernia: and when he interrogated his mother closely, she at first denied, and then she at last confessed her sin. When she had done penance according to the judgment of the saint, she was absolved, wondering very much all the while at what was made known to the saint regarding her.
