There was one fair lady especially whom Sandro loved to paint--the beautiful Simonetta, as she is still called.

First he painted her as Venus, who was born of the sea foam. In his picture she floats to the shore standing in a shell, her golden hair wrapped round her. The winds behind blow her onward and scatter pink and red roses through the air. On the shore stands Spring, who holds out a mantle, flowers nestling in its folds, ready to enwrap the goddess when the winds shall have wafted her to land.

Then again we see her in his wonderful picture of `Spring,' and in another called `Mars and Venus.' She was too great a lady to stoop to the humble painter, and he perhaps only looked up to her as a star shining in heaven, far out of the reach of his love. But he never ceased to worship her from afar. He never married or cared for any other fair face, just as the great poet Dante, whom Botticelli admired so much, dreamed only of his one love, Beatrice.

But Sandro did not go sadly through life sighing for what could never be his. He was kindly and good-natured, full of jokes, and ready to make merry with his pupils in the workshop.

It once happened that one of these pupils, Biagio by name, had made a copy of one of Sandro's pictures, a beautiful Madonna surrounded by eight angels. This he was very anxious to sell, and the master kindly promised to help him, and in the end arranged the matter with a citizen of Florence, who offered to buy it for six gold pieces.

`Well, Biagio,' said Sandro, when his pupil came into the studio next morning, `I have sold thy picture. Let us now hang it up in a good light that the man who wishes to buy it may see it at its best. Then will he pay thee the money.'

Biagio was overjoyed.

`Oh, master,' he cried, `how well thou hast done.'

Then with hands which trembled with excitement the pupil arranged the picture in the best light, and went to fetch the purchaser.

Now meanwhile Botticelli and his other pupils had made eight caps of scarlet pasteboard such as the citizens of Florence then wore, and these they fastened with wax on to the heads of the eight angels in the picture.

Presently Biagio came back panting with joyful excitement, and brought with him the citizen, who knew already of the joke. The poor boy looked at his picture and then rubbed his eyes. What had happened? Where were his angels? The picture must be bewitched, for instead of his angels he saw only eight citizens in scarlet caps.

He looked wildly around, and then at the face of the man who had promised to buy the picture. Of course he would refuse to take such a thing.

But, to his surprise, the citizen looked well pleased, and even praised the work.

`It is well worth the money,' he said; `and if thou wilt return with me to my house, I will pay thee the six gold pieces.'

Biagio scarcely knew what to do. He was so puzzled and bewildered he felt as if this must be a bad dream.

As soon as he could, he rushed back to the studio to look again at that picture, and then he found that the red-capped citizens had disappeared, and his eight angels were there instead. This of course was not surprising, as Sandro and his pupils had quickly removed the wax and taken off the scarlet caps.

`Master, master,' cried the astonished pupil, `tell me if I am dreaming, or if I have lost my wits? When I came in just now, these angels were Florentine citizens with red caps on their heads, and now they are angels once more. What may this mean?'

`I think, Biagio, that this money must have turned thy brain round,' said Botticelli gravely. `If the angels had looked as thou sayest, dost thou think the citizen would have bought the picture?'

`That is true,' said Biagio, shaking his head solemnly; `and yet I swear I never saw anything more clearly.'

And the poor boy, for many a long day, was afraid to trust his own eyes, since they had so basely deceived him.

But the next thing that happened at the studio did not seem like a joke to the master, for a weaver of cloth came to live close by, and his looms made such a noise and such a shaking that Sandro was deafened, and the house shook so greatly that it was impossible to paint.

But though Botticelli went to the weaver and explained all this most courteously, the man answered roughly, `Can I not do what I like with my own house?' So Sandro was angry, and went away and immediately ordered a great square of stone to be brought, so big that it filled a waggon. This he had placed on the top of his wall nearest to the weaver's house, in such a way that the least shake would bring it crashing down into the enemy's workshop.

When the weaver saw this he was terrified, and came round at once to the studio.

`Take down that great stone at once,' he shouted. `Do you not see that it would crush me and my workshop if it fell?'

`Not at all,' said Botticelli. `Why should I take it down? Can I not do as I like with my own house?'

And this taught the weaver a lesson, so that he made less noise and shaking, and Sandro had the best of the joke after all.

There were no idle days of dreaming now for Sandro. As soon as one picture was finished another was wanted. Money flowed in, and his purse was always full of gold, though he emptied it almost as fast as it was filled. His work for the Pope at Rome alone was so well paid that the money should have lasted him for many a long day, but in his usual careless way he spent it all before he returned to Florence.
