Returning to Lucca for the feast of St. Martin, the emperor took that opportunity of publicly placing on the head of Castruccio the ducal circle, investing him with the states of Lucca, Pistoia, Volterra, and the bishopric of Luni, conferring on him the privilege of quartering the royal arms of Bavaria with his own, besides an unscrupulous donation of the Pisan towns of Serrezzano, Rotina, Montecalvole, and Pietra Cassa. The ceremony of receiving the ducal coronet from an emperor’s hands, Castruccio’s great power, talents, and influence, and the universal feeling that this title would not long continue vain and empty, but become in substance as in name the first dukedom in Italy since the time of the ancient Lombards, altogether imparted a solemn and imposing character to the transaction which increased the apprehensions of every Italian Guelf; nor was the Ghibelline Pisa less anxious or discontented to see four of her walled towns quietly made over to Castruccio as a coronation gift--an earnest, as it seemed to be, of her own destiny. The duke of Calabria, knowing that Castruccio was unwillingly compelled to follow Ludwig, who resumed his march towards Rome on the 15th of December, also prepared to quit Florence, leaving Philip Sanguineto with a thousand men-at-arms as his vicar. At a public feast he took leave of the Florentines, promising to return when the kingdom of Naples should be safe, and departed on the 27th of December, the same day that Castruccio by another road marched from Lucca to join the imperialists. [Sidenote: [1327-1328 A.D.]] Charles governed despotically, like every ruler of that age; for liberty then consisted in the privilege of being eligible to govern and choose governors, rather than in being governed well; and although in doing so he tyrannically condemned a citizen of rank who with as much reason as insolence opposed the grant of a subsidy to King Robert, thereby proving that freedom no longer existed in Florence, yet he made himself a favourite with the citizens by great personal urbanity and his endeavours to reconcile private feuds, together with considerable liberality and a generally impartial administration of justice. On the other hand, he was unpopular from his inactive, unwarlike character, and the excessive cost of his maintenance; this, according to Villani, who was employed in auditing the accounts, amounted in nine months to 900,000 florins; but as the greater part was circulated within the town, although a highly taxed people necessarily worked twice for the same money, it was still accompanied by great activity and some outward appearance of prosperity.
