But the key was always turned in the lock and the door was strong. There was the window, but it was high above the street, and the grey walls, built of huge square stones, might well have been intended to enclose a prison rather than a palace.
It was a dark night, and the air felt hot as Filippo leaned out of the window. Scarce a breath stirred the still air, and every sound could be heard distinctly. Far below in the street he could hear the tread of the people's feet, and catch the words of a merry song as a company of boys and girls danced merrily along.
'Flower of the rose,
If I've been happy, what matter who knows,'
they sang.
It was all too tempting; out he must get. Filippo looked round his room, and his eye rested on the bed. With a shout of triumphant delight he ran towards it. First he seized the quilt and tore it into strips, then the blankets, then the sheets.
'Whoever saw a grander rope?' he chuckled to himself as he knotted the ends together.
Quick as thought he tied it to the iron bar that ran across his window, and, squeezing out, he began to climb down, hand over hand, dangling and swinging to and fro. The rope was stout and good, and now he could steady himself by catching his toes in the great iron rings fastened into the wall, until at last he dropped breathless into the street below.
Next day, when Cosimo came to see how the painting went on, he saw indeed the pictures and the brushes, but no painter was there. Quickly he stepped to the open window, and there he saw the dangling rope of sheets, and guessed at once how the bird had flown.
Through the streets they searched for the missing painter, and before long he was found and brought back. Filippo tried to look penitent, but his eyes were dancing with merriment, and Cosimo must needs laugh too.
'After all,' said Filippo, 'my talent is not like a beast of burden, to be driven and beaten into doing its work. It is rather like one of those heavenly visitors whom we willingly entertain when they deign to visit us, but whom we can never force either to come or go at will.'
