Fra Benedetto's loving care saved the life of his adopted son. By the beginning of June Giovanni had so far recovered as to be able to walk; and then, notwithstanding all the warnings and the entreaties of the affectionate monk, he returned to Leonardo's studio.

Towards the close of July the army of Louis XII. of France, commanded by Marshal d'Aubigny, Louis of Luxemburg, and Gian Giacomo Trivulzio, crossed the Alps and burst down upon the plains of Lombardy.

CALM WATERS—1499-1500

'Le onde sonore e luminose sono governate dalle stesse leggi che governano le onde delle acque: l'angolo incidente deve eguagliare l'angolo riflettente.'

Leonardo da Vinci.

(The waves of light and sound are governed by the same mechanical law as that governing waves of water: the angle of incidence equals the angle of reflection.)

'Il duca ha perso lo Stato e la roba e la libertà; e nessuna sua opera si fini per lui.'

Leonardo da Vinci.

(The duke has lost state, wealth, and liberty; not one of his works will be finished by himself.)

The Duke's treasury, a subterranean chamber very long and narrow and piled with huge oak chests, was entered from the north-west tower of the Rocchetta by a small iron door set in the thickness of the wall and adorned with an unfinished painting by Leonardo. On the first night of September 1499, Messer Ambrogio Ferrari the court treasurer, and Messer Borgonzio Botta the comptroller of the ducal revenue, with their assistants, shovelled coins, pearls, and other treasures hastily from the oak chests, threw them into leathern bags, which they sealed with the ducal seal, and consigned to servants to be packed upon mules. Already two hundred and forty bags had been sealed and thirty mules had been loaded, yet the guttering candles still showed that the chests contained great heaps of silver. Il Moro, meanwhile, sat at a portable writing-desk heaped with registers and account-books, but gazed blankly at the flame of the candle, and paid no attention to the work of the treasurers. Since the terrible news had reached him of the defeat of Galeazzo Sanseverino, the commander of his forces, and of the inevitable nearing of the French, he seemed to have fallen into some strange torpor which resembled insensibility.

Presently Ambrogio Ferrari inquired whether the Duke wished to take the gold and silver plate also; but Ludovico, after frowning and apparently making an effort to attend, turned away, waved his hand, and once more fixed his eyes upon the candle. The question was repeated, but this time he did not even feign attention; and presently the treasurers, unable to obtain an answer, went away. Il Moro remained alone.

A few minutes later, the old chamberlain announced Messer Bernardino da Corte, the newly appointed commandant of the fortress. The Duke roused himself, passed his hand over his brow, and bade his approach.
