When the assembly broke up, Columba paid a visit to Aedh in his royal palace, when he sought and obtained the freedom of Scandlan Mor, son of the King of Ossory, whom the High King of Ireland had unjustly detained in prison. The eldest son of Aedh was perhaps a little uneasy at the prospect of the visit, for he had received a severe reproof from the Saint for holding the monks of Iona up to ridicule; but Domnal, his younger brother, attached himself to Columbcille with a boy's enthusiastic admiration for all that is great and noble. Columba was delighted with the manly young prince, and prophesied that his reign would be a long and happy one, on condition that he "received the Holy Communion every week, and tried to keep his promises." He would also, he said, "die on his own feather-bed," a rare enough thing in the days when a King of Ireland was pretty sure to fall on the field of battle or to perish by the hand of an assassin. Aedh himself had reason to be uneasy about the state of his soul, and asked Columba if any of the princes who had died during his reign were in heaven. He was told that three only had escaped the pains of purgatory and had entered into everlasting bliss. "And I," asked the King, "shall I save my soul?" "Not unless you repent heartily of all your sins and lead a better life," replied Columba; and Aedh resolved to take his advice. To all the princes of Ireland, especially to those who were of his own blood, Columbcille preached compassion and mercy towards their enemies, the forgiveness of injuries, and the recall of exiles. Many of the latter had passed by Iona as they went to seek shelter in a strange land, and his heart had grieved with them in their sorrow. He resolved also to visit his religious foundations in Ireland before he returned to the country of his adoption, and we can imagine the joy of the monks of Derry and Durrow who had never thought to look upon their beloved father's face again. The people came out in crowds to welcome him and carried a canopy of green branches over his head. Adamnan tells us of the miracles worked by the Saint on his journey, and how the labourers would leave their work as he passed and go before him singing hymns of joy. As he was about to enter one of the monasteries, a poor little boy, who was looked upon by everybody as an idiot on account of his stammering tongue and vacant eye, crept through the crowd and took hold of the border of Columba's cloak. The Saint turned round, and taking the child in his arms embraced him tenderly. "Show me your tongue," he said to the little boy, who was trembling with fear; and then, making the sign of the Cross over him, he turned to the bystanders, who were vexed that he should pay so much attention to an idiot. "This child whom you despise so much," he said, "will grow daily in wisdom and virtue; God will give to him eloquence and power; and when he has grown to man's estate he will be counted amongst the great ones of his country."
