'Not more impossible than that thy human mind should understand the mind of God,' said the child, gazing upwards at him with grave, sweet eyes.

And before the bishop could answer the child had vanished, and the saint knew that God had sent him as an answer to his troubled thoughts, and as a rebuke for his trying to understand the things that only God could know.

SAINT AUGUSTINE OF CANTERBURY

It was market-day in the great city of Rome, and the people were busy buying and selling and shouting, just as they do to-day with us, when market-day comes round. But there was a great difference between this Roman market and ours, a difference which would have seemed to us strange and cruel. For instead of sheep and oxen, or green vegetables from the country, they were selling men and boys, and even little maidens. There in the great market-place, with the sun beating down on their bare heads, they stood, looking with dull, despairing eyes, or with frightened glances at the crowds of buyers and sellers who were bargaining around.

Suddenly a hush fell on the crowd, and a stately figure was seen crossing the square. People stood aside and bent their heads in reverence as Gregory passed by, for he was Abbot of a great monastery in Rome, and was much beloved even by the rough Roman soldiers. He walked swiftly as if he did not care to linger in the market-place, for it grieved his gentle heart to see the suffering of the slaves when he could do nothing to help them.

But suddenly the crowd seemed to divide in front of him, and he stopped in wonder at the sight which met his eyes. It was only a group of little fair-haired English boys who had been captured in the wars, and carried off to be sold as slaves in the Roman market. But Gregory had never seen anything like them before. All around were dark-eyed, swarthy-faced Italians, or darker-skinned slaves from Africa, and these boys with their sunny, golden hair, fair faces, and eyes blue as the sky overhead, seemed to him creatures from a different world.

'Whence come these children, and what name do they bear?' asked the bishop of a man who stood beside him.

'From a savage island far over the sea,' he answered, 'and men call them Angles.'

Then the kind bishop looked with pitying eyes upon the beautiful children, and said to himself, as he turned to go: 'They should be called not Angles, but angels.'
