27/39 * Note: Compare Gibbon, ch.xi.note 43, and xxxi. "It is quite clear," observes Sir J.Hobhouse, "that all these measurements differ, (in the first and second it is 21, in the text 12 and 345 paces, in the last 10,) yet it is equally clear that the historian avers that they are all the same." The present extent, 12 3/4 nearly agrees with the second statement of Gibbon.Sir. J.Hobhouse also observes that the walls were enlarged by Constantine; but there can be no doubt that the circuit has been much changed.Illust.of Ch. |
