it was rough and ill made, and would need much attention before it would be possible to paint it. The first thing he did was to hold the shield before the fire till the fibres were softened and the crookedness could be straightened out. The surface was then planed and made smooth, and covered with gypsum.
So far he had not thought what the picture should be, but now he began to consider this important matter, and as he pondered a look of mischief danced in his eyes.
'I know! That will do!' he said to himself. 'The person who owns it, whoever he is, shall be as frightened as if he saw the head of Medusa; only, instead of being turned to stone, he will most likely run away!' And still smiling, Leonardo left the workshop and went to his room, taking the shield in a cloth. Then he went out into the fields and hunted about till he had collected a quantity of strange creatures, hedgehogs, lizards, tadpoles, locusts, snakes and many others, for he knew as much about what is called 'Natural History' as he did about everything else, and could tell exactly where these animals could be found.

He then sat down and began to place them so as to cause them to form one horrible monster, with eyes and legs everywhere. It was a long time before he could make anything horrid enough to please him; again and again he undid his work, and tried to combine his creatures differently, but at last something so terrible stared him in the face that he almost felt frightened.

Flames poured from it on every side, and a cloud of vapour rose upwards from its many nostrils. After days of hard labour, during which the animals died and filled the room with a smell from which even a boy might well be expected to shrink, Leonardo visited his father
