Note 3572 — THE JULIAN CALENDAR AND THE CHRONOLOGY OF CAESAR’S INVASIONS OF BRITAIN

Cäsars gall. Krieg und Theile seines Bürgerkriegs, ii, 1880, p. 199. See also A. W. Zumpt (Jahrbücher für classische Philologie, vii. Supplementband, 1873-5, p. 556), who, in my opinion, proves his point. Mommsen (Die röm. Chron. bis auf Caesar, 1859, p. 277) maintains that the mere fact that the two extraordinary intercalary months were called prior and posterior respectively, not secundus and tertius, proves that the intercalary month inserted before March, 708, was not regarded as belonging to the calendar year 708 at all, but only to the consular year; in other words, that the calendar year began on the 1st of January in 709 for the first time. This view is severely, and I think justly, criticized by Bergk (Jahrbücher für classische Philologie, 13 Supplementband, 1884, pp. 631-5).
