Note 454 — BOOK II. AN ACCOUNT OF THE WORLD AND THE ELEMENTS. (continued 2)

“... Alpium vertices, longo tractu, nec breviore quinquaginta millibus passuum assurgere.” To avoid the apparent improbability of the author conceiving of the Alps as 50 miles high, the commentators have, according to their usual custom, exercised their ingenuity in altering the text. See Poinsinet, i. 206, 207, and Lemaire, i. 373. But the expression does not imply that he conceived them as 50 miles in perpendicular height, but that there is a continuous ascent of 50 miles to get to the summit. This explanation of the passage is adopted by Alexandre; Lemaire, ut supra. For what is known of Dicæarchus I may refer to Hardouin, Index Auctorum, in Lemaire, i. 181.
