Leonardo shrugged his shoulders.

'As you please, my lord. Entrust it to Bramante.'

'Nay, be not offended. I have no thought of slighting you.' And they fell to bargaining.

'Va bene, va bene!' said the duke at last, deferring the conclusion of the agreement; and he took up Leonardo's sketch-book and turned over the unfinished drawings, chiefly architectural and mechanical: the artist, somewhat impatient, had to furnish explanations and commentaries.

On one sheet there was a huge mausoleum, an artificial mountain crowned with a colonnaded temple, its dome pierced like that of the Pantheon; on the next, the exact calculations and the ground-plan for the edifice, with details for the disposition of stairs, cells, corridors; the whole being destined for the reception of five hundred sepulchral urns.

'What is this?' asked the duke; 'when and for whom have you designed it?'

'For no one. 'Tis a fantasy.'

'Strange fantasy!' commented Ludovico shaking his head; ''tis a cemetery for the gods or the Titans, like a building in a city of dreams.'

The next sketch showed the plan for a town with the streets in tiers, one above the other, the upper for the rich, the lower for the poor, for animals, and for refuse; a town to be built in conformity with natural laws; for men without a conscience to be offended by glaring inequality.

'Not so bad!' observed the duke. 'You think it would be practicable?'
