The del Dongo family had constructed it in the fifteenth century, as was everywhere attested by marble tablets charged with their arms; one could still see the drawbridges and deep moats, though the latter, it must be admitted, had been drained of their water; but with its walks eighty feet in height and six in thickness, this castle was safe from assault, and it was for this reason that it was dear to the timorous Marchese. Surrounded by some twenty-five or thirty retainers whom he supposed to be devoted to his person, presumably because he never opened his mouth except to curse them, he was less tormented by fear than at Milan.

This fear was not altogether groundless: he was in most active correspondence with a spy posted by Austria on the Swiss frontier three leagues from Grianta, to contrive the escape of the prisoners taken on the field of battle; conduct which might have been viewed in a serious light by the French generals.
