The little boy who trotted barefoot along by the side of his father had a sweet, serious little face, but he looked tired and hungry, and scarcely fit for such a long rough walk. They had started from their home at Castello delle Pieve very early that morning, and the piece of black bread which had served them for breakfast had been but small. Away in front stretched that long, white, never-ending road; and the little dusty feet that pattered so bravely along had to take hurried runs now and again to keep up with the long strides of the man, while the wistful eyes, which were fixed on that distant town, seemed to wonder if they would really ever reach their journey's end.

'Art tired already, Pietro?' asked the father at length, hearing a panting little sigh at his side. 'Why, we are not yet half-way there! Thou must step bravely out and be a man, for to-day thou shalt begin to work for thy living, and no longer live the life of an idle child.'

The boy squared his shoulders, and his eyes shone.

'It is not I who am tired, my father,' he said. 'It is only that my legs cannot take such good long steps as thine; and walk as we will the road ever seems to unwind itself further and further in front, like the magic white thread which has no end.'

The father laughed, and patted the child's head kindly.

'The end will come ere long,' he said. 'See where the mist lies at the foot of the hill; there we will begin to climb among the olive-trees and leave the dusty road. I know a quicker way by which we may reach the city. We will climb over the great stones that mark the track of the stream, and before the sun grows too hot we will have reached the city gates.'

It was a great relief to the little hot, tired feet to feel the cool grass beneath them, and to leave the dusty road. The boy almost forgot his tiredness as he scrambled from stone to stone, and filled his hands with the violets which grew thickly on the banks, scenting the morning air with their sweetness. And when at last they came out once more upon the great white road before the city gates, there was so much to gaze upon and wonder at, that there was no room for thoughts of weariness or hunger.

There stood the herds of great white oxen, patiently waiting to pass in. Pietro wondered if their huge wide horns would not reach from side to side of the narrow street within the gates. There the shepherd-boys played sweet airs upon their pipes as they walked before their flocks, and led the silly frightened sheep out of the way of passing carts. Women with bright-coloured handkerchiefs tied over their heads crowded round, carrying baskets of fruit and vegetables from the country round. Carts full of scarlet and yellow pumpkins were driven noisily along. Whips cracked, people shouted and talked as much with their hands as with their lips, and all were eager to pass through the great Etruscan gateway, which stood grim and tall against the blue of the summer sky. Much good service had that gateway seen, and it was as strong as when it had been first built hundreds of years before, and was still able to shut out an army of enemies, if Perugia had need to defend herself.

Pietro and his father quickly threaded their way through the crowd, and passed through the gateway into the steep narrow street beyond. It was cool and quiet here. The sun was shut out by the tall houses, and the shadows lay so deep that one might have thought it was the hour of twilight, but for the peep of bright blue sky which showed between the overhanging eaves above. Presently they reached the great square market-place, where all again was sunshine and bustle, with people shouting and selling their wares, which they spread out on the ground up to the very steps of the cathedral and all along in front of the Palazzo Publico. Here the man stopped, and asked one of the passers-by if he could direct him to the shop of Niccolo the painter.

'Yonder he dwells,' answered the citizen, and pointed to a humble shop at the corner of the market-place. 'Hast thou brought the child to be a model?'
