Gibbon anticipated Captain Mahan. In speaking of a naval battle between the fleet of Justinian and that of the Goths in which the galleys of the Eastern empire gained a signal victory, he wrote, "The Goths affected to depreciate an element in which they were unskilled; but their own experience confirmed the truth of a maxim, that the master of the sea will always acquire the dominion of the land."[112] But Gibbon's anticipation was one of the frequent cases where the same idea has occurred to a number of men of genius, as doubtless Captain Mahan was not aware of this sentence any more than he was of Bacon's and Raleigh's epitomes of the theme which he has so originally and brilliantly treated.[113] No modern historian has been the subject of so much critical comment as Gibbon. I do not know how it will compare in volume with either of the similar examinations of Thucydides and Tacitus; but the criticism is of a different sort. The only guarantee of the honesty of Tacitus, wrote Sainte-Beuve, is Tacitus himself;[114] and a like remark will apply to Thucydides. But a fierce light beats on Gibbon. His voluminous notes furnish the critics the materials on which he built his history, which, in the case of the ancient historians, must be largely a matter of conjecture. With all the searching examination of "The Decline and Fall," it is surprising how few errors have been found and, of the errors which have been noted, how few are really important. Guizot, Milman, Dr. Smith, Cotter Morison, Bury, and a number of lesser lights have raked his text and his notes with few momentous results. We have, writes Bury, improved methods over Gibbon and "much new material of various kinds," but "Gibbon's historical sense kept him constantly right in dealing with his sources"; and "in the main things he is still our master."[115] The man is generally reflected in his book. That Gibbon has been weighed and not found wanting is because he was as honest and truthful as any man who ever wrote history. The autobiographies and letters exhibit to us a transparent man, which indeed some of the personal allusions in the history might have foreshadowed. "I have often fluctuated and shall _tamely_ follow the Colbert Ms.," he wrote, where the authenticity of a book was in question.[116] In another case "the scarcity of facts and the uncertainty of dates" opposed his attempt to describe the first invasion of Italy by Alaric.[117] In the beginning of the famous Chapter XLIV which is "admired by jurists as a brief and brilliant exposition of the principles of Roman law,"[118] Gibbon wrote, "Attached to no party, interested only for the truth and candor of history, and directed by the most temperate and skillful guides, I enter with just diffidence on the subject of civil law."[119] In speaking of the state of Britain between 409 and 449, he said, "I owe it to myself and to historic truth to declare that some _circumstances_ in this
