was such a thing as an Idea, and they felt uneasily apprehensive, like beasts of prey who have for the first time sniffed gunpowder.  The railleries and mockeries of Mantua’s neighbours, moreover, stimulated Mantua’s citizens to persevere in their course, and deterred them from doing aught to approve themselves fools.  Were not Verona, Cremona, Lodi, Pavia, Crema, cities that could never enthrone the Virgil they had never produced, watching with undissembled expectation to see them trip?  The hollow-hearted Eustachio and the rapacious Leonardo, their virtual rulers, might indeed be little sensible to this enthusiasm, but they could not disregard the general drift of public opinion, which said clearly:  “Mantua is trying a great experiment.  Woe to you if you bring it to nought by your selfish quarrels!”

The best proof that there was something in Manto’s idea was that after a while the Emperor Frederick took alarm, and signified to the Mantuans that they must cease their mumming and fooling and acknowledge him as their sovereign, failing which he would besiege their city.

Mantua was girt by a zone of fire and steel.  Her villas and homesteads flamed or smoked; her orchards flared heavenward in a torrent of sparks or stood black sapless trunks charred to their inmost pith; the promise of her harvests lay as grey ashes over the land.  But her ramparts, though breached in places, were yet manned by her sons, and their assailants recoiled pierced by the shafts or stunned by the catapults of the defence.  Kaiser Frederick sat in his tent, giving secret audience to one who had stolen in disguise over from the city in the grey of the morning.  By the Emperor’s side stood a tall martial figure, wearing a visor which he never removed.

“Your Majesty,” Leonardo was saying, for it was he, “this madness will soon pass away.  The people will weary of sacrificing themselves for a dead heathen.”

“And Liberty?” asked the Emperor, “is not that a name dear to those misguided creatures?”

“So dear, please your Majesty, that if they have but the name they will perfectly dispense with the thing.  I do not advise that your imperial yoke should be too palpably adjusted to their stiff necks.  Leave them in appearance the choice of their magistrate, but insure its falling upon one of approved fidelity, certain to execute obsequiously all your Majesty’s mandates; such an one, in short, as your faithful vassal Leonardo.  It would only be necessary to decapitate that dangerous revolutionist, Eustachio.”

“And the citizens are really ready for this?”

“All the respectable citizens.  All of whom your Majesty need take account.  All men of standing and substance.”

“I rejoice to hear it,” said the Emperor, “and do the more readily credit thee inasmuch as a most virtuous and honourable citizen hath already been beforehand with thee, assuring me of the same thing, and affirming that but one traitor, whose name, methinks, sounded like thine, stands between me and the subjugation of Mantua.”
