That the defence which was made with Ravenna for its citadel was not wholly victorious, that the attack which the eastern empire planned and delivered from Ravenna, perhaps too late, was not completely successful, were the results of many and various causes, but not of any want of Judgment in the choice of Ravenna as their base. That base was rightly and consummately chosen without hesitation and from the first; and because it was chosen, the hope of the restoration never quite passed away and seemed to have been realised at last when Charlemagne, following Pepin into Italy, was crowned emperor in S. Peter's Church on Christmas Day in the year 800.
It will readily be understood, then, that the most important and the most interesting part of the history of Ravenna begins when Honorius retreated upon her before the invasion of Alaric, and not only the West, but Italy and Rome, the heart and soul of it, seemed about to be in dispute.
But first amid all the loose thought and confusion of the last three hundred years let us make sure of fundamentals.
I shall take for granted in this book that Rome accepted the Faith not because the Roman mind was senile, but because it was mature; that the failure of the empire is to be regretted; that the barbarians were barbarians; that not from them but from the new and Christian civilisation of the empire itself came the strength of the restoration, the mighty achievements of the Middle Age, of the Renaissance, of the Modern world. The barbarian, as I understand it, did nothing. He came in naked and ashamed, without laws or institutions. To some extent, though even in this he was a failure, he destroyed; it was his one service. He came and he tried to learn; he learnt to be a Christian. When the empire re-arose it was Roman not barbarian, it was Christian not heathen, it was Catholic not heretical. It owed the barbarian nothing. That it re-arose, and that as a Roman and a Catholic state, is due largely to the fact that Honorius retreated upon Ravenna.
If we could depend upon the dates in the Theodosian Code we should be able to say that Honorius finally retreated upon Ravenna before December 402;[1] unhappily the dates we find there must not be relied upon with absolute confidence. We may take it that Alaric entered Venetia in November 401, and that at the same time Radagaisus invaded Rhaetia. Stilicho, Honorius' great general and the hero of the whole defence, advanced against Radagaisus. Upon Easter Day in the following year, however, he met Alaric at Pollentia and defeated him, but the Gothic king was allowed to withdraw from that field with the greater part of his cavalry entire and unbroken. Stilicho hoping to annihilate him forced him to retreat, overtook him at Asta (Asti), but again allowed him to escape and this time to retreat into Istria.
[Footnote 1: Cf. Hodgkin, Italy and her Invaders, vol. i. pt. 2, p. 712.]
In the summer of 403 Alaric again entered Italy and laid siege to Verona; Stilicho, however, met him and defeated him, but again allowed him to retreat. Well might Orosius, his contemporary, exclaim that this king with his Goths, though often hemmed in, often defeated, was always allowed to escape.
The battle of Verona was followed by a peace of two years duration. But in 405 the other barbarian Radagaisus came down into Cisalpine Gaul as Alaric had done, and Stilicho, knowing that the pass through which the great road entered Italy was secured by Ravenna, assailed him at Ticinum (Pavia). Radagaisus, however, did a bold and perhaps an unexpected thing. He attempted to cross the Apennines themselves by the difficult and neglected route that ran over them and led to Fiesole.[2] But the Romans had been right in their judgment. That way was barred by nature. It needed no defence. Before the barbarian had quite pierced the mountains Stilicho caught him, slew him, and annihilated his already starving bands at Fiesole. Cisalpine Gaul and the fortress of Ravenna, its key, still held Italy secure.
[Footnote 2: Livy asserts that C. Flamimus, the colleague of M. Aemilius Lepidus in B.C. 187, built a road direct from Arezzo to Bologna across the Tuscan Apennines. This road early fell into disuse and ruin. We hear nothing of it (but see Cicero, Phil. xii. 9) till this raid of Radagaisus. Later, Totila came this way to besiege Rome. Cf. Repetti, Dizionavio della Toscana, vol. v. 713-715.]
Honorius and his great general and minister now essayed what perhaps should have been attempted earlier, namely, to employ Alaric in the service of Rome, as the East had known how to employ him, at a distance from the capital. He was first offered the province of Illyricum; but the senate refused to hear of any such treaty, and though at last it consented to pay the Goth 4000 pounds in gold "to secure the peace of Italy and conciliate the friendship of the Gothic king," Lampadius, one of the most illustrious members of that assembly, asserted that "this is not a treaty of peace but of servitude." Thus the senate was alienated from Stilicho, and not the senate only but the army also, which was exasperated by his affection for the barbarians. Nor was the great general more fortunate with the emperor, who had come of late under the influence of Olympius, a man who, Zosimus tells us, under an appearance of Christian piety, concealed a great deal of rascality. Stilicho had promoted him to a very honourable place in the household of the emperor; nevertheless he plotted against him. At his suggestion Honorius proposed to show himself to the army at Pavia, already at enmity with Stilicho. The result was disastrous. For the occasion was seized for a revolt in which the best officers of the empire perished. Stilicho, not daring to march his barbarians from Bologna upon the Roman army, and by this refusal incurring their enmity also, flung himself into Ravenna and took refuge in the great church there. On the following day, however, he was delivered up by the bishop to Count Heraclian and slain.
