'Dost thou think thou canst make aught of the boy?' he asked, spreading out the drawings before Verocchio.

The painter's quick eyes examined the work with deep interest.

'Send him to me at once,' he said. 'This is indeed marvellous talent.'

So Leonardo entered the studio as a pupil, and learned all that could be taught him with the same quickness with which he learned anything that he cared to know.

Every one who saw his work declared that he would be the wonder of the age, but Verocchio shook his head.

'He is too wonderful,' he said. 'He aims at too great perfection. He wants to know everything and do everything, and life is too short for that. He finishes nothing, because he is ever starting to do something else.'

Verocchio's words were true; the boy seldom worked long at one thing. His hands were never idle, and often, instead of painting, he would carve out tiny windmills and curious toys which worked with pulleys and ropes, or made exquisite little clay models of horses and all the other animals that he loved. But he never forgot the longing that had filled his heart when he was a child--the desire to learn the secret of flying.

For days he would sit idle and think of nothing but soaring wings, then he would rouse himself and begin to make some strange machine which he thought might hold the secret that he sought.

'A waste of time,' growled Verocchio. 'See here, thou wouldst be better employed if thou shouldst set to work and help me finish this picture of the Baptism for the good monks of Vallambrosa. Let me see how thou canst paint in the kneeling figure of the angel at the side.'

For a while the boy stood motionless before the picture as if he was looking at something far away. Then he seized the brushes with his left hand and began to paint with quick certain sweep. He never stopped to think, but worked as if the angel were already there, and he were but brushing away the veil that hid it from the light.
