There is a curious story also related of Gregory in his walks through Rome, the issue of which, could an unbelieving age put faith in it, would be even more remarkable. One day as he passed by the Forum of Trajan--then no doubt a spot more wildly ruinous than now, though still with some of its great galleries and buildings standing among overthrown monuments and broken pillars--some one told him the story of Trajan and the widow, which must have greatly affected the mediæval imagination since Dante has introduced it in his great poem. The prayer addressed to the Emperor on his way to the wars was the same as that of the widow in the parable, "Avenge me of mine adversary." "I will do so when I return," the Emperor replied. "But who will assure me that you will ever return?" said the importunate widow; upon which the Emperor, recognising the justice of the objection, stopped his warlike progress until he had executed the vengeance required, upon one of his own officials (is it not said by one authority his own son?) who had wronged her. Gregory was as much impressed by this tale as Dante. He went on lamenting that such a man, so just, so tolerant of interruption, so ready to do what was right, should be cut off from the Divine mercy. He carried this regret with him all the way to the tomb of the apostles, where he threw himself on his knees and prayed with all his heart that the good Trajan, the man who did right according to the light that was in him, at all costs, should be saved. Some versions of the story add that he offered to bear any penance that might be put upon him for his presumption, and was ready to incur any penalty to secure this great boon. It can never be put to proof in this world whether Gregory's petition was heard or not, but his monks and biographers were sure of it, and some of them allege that his own bodily sufferings and weakness were the penalty which he accepted gladly for the salvation of that great soul. The story proves at least the intense humanity and yearning over the unhappy, which was in his heart. Whether he played and punned in tender humour with the objects of his sympathy, or so flung himself in profoundest compassion into the abyss of hopelessness with them, that he could wish himself like Paul accursed for his brethren's sake--Gregory's being was full of brotherly love and fervent feeling, a love which penetrated even beyond the limits of visible life.
