By way of having yet another different spectacle, there was built with singular mastery on the vast Piazza di S. Maria Novella a most beautiful castle, with all the proper appurtenances of ramparts, cavaliers, casemates, curtains, ditches and counterditches, secret and public gates, and, finally, all those considerations that are required in good and strong fortifications; and in it was placed a good number of valorous soldiers, with one of the principal and most noble lords of the Court as their captain, a man determined on no account ever to be captured. That magnificent spectacle being divided into two days, on the first day there was seen appearing in most beautiful order from one side a fine and most ornate squadron of horsemen all in armour and in battle-array, as if about to meet real enemies in combat, and from the other side, with the aspect of a massive and well-ordered army, some companies of infantry with their baggage, waggons of munitions, and artillery, and with their pioneers and sutlers, all drawn close together, as is customary amid the dangers of real wars; these likewise having a similar lord of great experience and valour as captain, who was seen urging them on from every side, and fulfilling his office most nobly. And after the attackers had been reconnoitred several times and in various ways, with valour and artifice, by those within the castle, and various skirmishes had been fought, now by the horsemen and now by the infantry, with a great roar of musketry and artillery, and charges had been delivered and received, and several ambuscades and other suchlike stratagems of war had been planned with astuteness and ingenuity; finally the defenders were seen, as if overcome by the superior force, to begin little by little to retire, and in the end it seemed that they were constrained to shut themselves up completely within the castle. But the second day, after they had, as it were during the night, constructed their platforms and gabionade and planted their artillery, there was seen to begin a most terrible bombardment, which seemed little by little to throw a part of the walls to the ground; after which, and after the explosion of a mine, which in another part, in order to keep the attention of the defenders occupied, appeared to have made a passing wide breach in the wall, the places were reconnoitred and the cavalry drew up in most beautiful battle-array, and then was seen now one company moving up, and now another, some with ladders and some without, and many valorous and terrible assaults delivered in succession and repeated several times, and ever received by the others with skill, boldness, and obstinacy, until in the end it was seen that the defenders, weary, but not vanquished, made an honourable compact with the attackers to surrender the place to them, issuing from it, with marvellous satisfaction for the spectators, in military order, with their banners unfurled, their drums, and all their usual baggage.
