The History of the Decline and Fall of the Roman Empire - Edward Gibbon [113]
[Footnote 18: Mr. Hume is justly surprised at a passage of Herodian, (l. iv. p. 139,) who, on this occasion, represents the Imperial palace as equal in extent to the rest of Rome. The whole region of the Palatine Mount, on which it was built, occupied, at most, a circumference of eleven or twelve thousand feet, (see the Notitia and Victor, in Nardini's Roma Antica.) But we should recollect that the opulent senators had almost surrounded the city with their extensive gardens and suburb palaces, the greatest part of which had been gradually confiscated by the emperors. If Geta resided in the gardens that bore his name on the Janiculum, and if Caracalla inhabited the gardens of Maecenas on the Esquiline, the rival brothers were separated from each other by the distance of several miles; and yet the intermediate space was filled by the Imperial gardens of Sallust, of Lucullus, of Agrippa, of Domitian, of Caius, &c., all skirting round the city, and all connected with each other, and with the palace, by bridges thrown over the Tiber and the streets. But this explanation of Herodian would require, though it ill deserves, a particular dissertation, illustrated by a map of ancient Rome. (Hume, Essay on Populousness of Ancient Nations. - M.)]

This latent civil war already distracted the whole government, when a scheme was suggested that seemed of mutual benefit to the hostile brothers. It was proposed, that since it was impossible to reconcile their minds, they should separate their interest, and divide the empire between them. The conditions of the treaty were already drawn with some accuracy. It was agreed that Caracalla, as the elder brother should remain in possession of Europe and the western Africa; and that he should relinquish the sovereignty of Asia and Egypt to Geta, who might fix his residence at Alexandria or Antioch, cities little inferior to Rome itself in wealth and greatness; that numerous armies should be constantly encamped on either side of the Thracian Bosphorus, to guard the frontiers of the rival monarchies; and that the senators of European extraction should acknowledge the sovereign of Rome, whilst the natives of Asia followed the emperor of the East. The tears of the empress Julia interrupted the negotiation, the first idea of which had filled every Roman breast with surprise and indignation. The mighty mass of conquest was so intimately united by the hand of time and policy, that it required the most forcible violence to rend it asunder. The Romans had reason to dread, that the disjointed members would soon be reduced by a civil war under the dominion of one master; but if the separation was permanent, the division of the provinces must terminate in the dissolution of an empire whose unity had hitherto remained inviolate. ^20

Had the treaty been carried into execution, the sovereign of Europe might soon have been the conqueror of Asia; but Caracalla obtained an easier, though a more guilty, victory. He artfully listened to his mother's entreaties, and consented to meet his brother in her apartment, on terms of peace and reconciliation. In the midst of their conversation, some centurions, who had contrived to conceal themselves, rushed with drawn swords upon the unfortunate Geta. His distracted mother strove to protect him in her arms; but, in the unavailing struggle, she was wounded in the hand, and covered with the blood of her younger son, while she saw the elder animating and assisting ^21 the fury of the assassins. As soon as the deed was perpetrated, Caracalla,
