But in after years, one by one, all the great artists would come to that little chapel of the Carmine there to learn their first lessons from those life-like figures. Especially they would stand before the fresco which shows St. Peter baptizing a crowd of people. And in that fresco they would study more than all the figure of a boy who has just come out of the water, shivering with cold, the most natural figure that had ever been painted up to that time. All things must be learnt little by little, and each new thing we know is a step onwards. So this figure of the shivering boy marks a higher step of the golden ladder of Art than any that had been touched before. And this alone would have made the name of Masaccio worthy to be placed upon the list of world's great painters. FRA FILIPPO LIPPI It was winter time in Florence. The tramontana, that keen wind which blows from over the snow mountains, was sweeping down the narrow streets, searching out every nook and corner with its icy breath. Men flung their cloaks closer round them, and pulled their hats down over their eyes, so that only the tips of their noses were left uncovered for the wind to freeze. Women held their scaldinoes, little pots of hot charcoal, closer under their shawls, and even the dogs had a sad, half-frozen look. One and all longed for the warm winds of spring and the summer heat they loved. It was bad enough for those who had warm clothes and plenty of polenta, but for the poor life was very hard those cold wintry days. In a doorway of a great house, in one of the narrow streets, a little boy of eight was crouching behind one of the stone pillars as he tried to keep out of the grip of the tramontana. His little coat was folded closely round him, but it was full of rents and holes so that the thin body inside was scarcely covered, and the child's blue lips trembled with the cold, and his black eyes filled with tears. It was not often that Filippo turned such a sad little face to meet the world. Usually those black eyes sparkled with fun and mischief, and the mouth spread itself into a merry grin. But to-day, truly things were worse than he ever remembered them before, and he could remember fairly bad times, too, if he tried. Other children had their fathers and mothers who gave them food and clothes, but he seemed to be quite different, and never had had any one to care for him. True, there was his aunt, old Mona Lapaccia, who said he had once had a father and mother like other boys, but she always added with a mournful shake of her head that she alone had endured all the trouble and worry of bringing him up since he was two years old. 'Ah,' she would say, turning her eyes upwards, 'the saints alone know what I have endured with a great hungry boy to feed and clothe.'
