"Adams's skill as a literary craftsman has rarely been excelled by anyone writing in the English language, and certainly by no American historian. Any historian who ventures into territory where Henry Adams trod does so with either trepidation or foolhardy courage—lest one offend not only Clio, the muse of History, but also Calliope, the muse of Epic Poetry."
