In the Divine Comedy the theme of Rome’s glory receives an equally enthusiastic and a more poetic treatment. Its echoes ring all through the great poem, they become clamant and compelling in the Sixth Canto of the _Paradiso_, where, from the mouth of Justinian, in the Heaven of the world’s Workers, flows the story of the majestic flight of that “Uccel di Dio,” the Roman Eagle, through the centuries from Aeneas to Charlemagne.[50] But the atmosphere of serene satisfaction which pervades the _Monarchia_ is not maintained here. The opening Paean of triumph gives place to a more mournful note when the great Lawgiver turns to denounce the factions of later times: “the Guelphs striving to Frenchify Italy, the Ghibellines to Germanise it.”[51] Bitterly he assails the unworthy partisans of the Empire. The Eagle stands for Justice; let them practise their intrigues under some other standard[52]— Faccian li Ghibellin, faccian lor arte Sott’altro segno.... Here practice comes to blows with theory. The Roman “Monarchy” was, in Dante’s days, a failure. This failure was partly due to negligence of individual occupants of the throne of the Caesars, like Rudolf and Albert of Hapsburg,[53] partly to the usurping pretensions of the Papacy,[54] partly, again, to the turbulent, anarchic, and self-seeking spirit of cities and states.[55] It was Dante’s misfortune to be born into a world seething with political faction, and into an Italy and a Florence in which the fever of faction was at its hottest.[56] The two most potent influences in Christendom—the Papacy and the Holy Roman Empire—were at feud; and half the people of Italy (largely, if the truth must be told, to justify their existing group-enmities) sided with the Papacy, and called themselves “Guelfs,” half with the Empire, and called themselves “Ghibellines.” It is a mark of Dante’s greatness that, unlike most of his contemporaries, he was able to hold the balance true; to realise the immense value of each Authority, the Spiritual and the Temporal, if rightly wielded; to discern the God-given responsibility of each, and their mutual independence. Exiled himself from Florence by political faction, victim of the ruthless partisan spirit which ruled in his native city, he felt keenly the need of a supreme controlling power, a generally accepted and incorruptible Court of Appeal; and he looked forward to the descent into Italy of the Emperor Henry VII in 1311 as to the return of a Golden Age[57]—of a Peace long wept for, and still delayed:[58] Della molt’ anni lagrimata pace. Many think that the _Monarchia_ was written to celebrate this advent of one to whom he is not afraid to address the sacred words: “_Ecce Agnus Dei, ecce qui tollit peccata mundi!_”[59]
