SECTION II.-THE TABLES.

The several æras mentioned by Censorinus having been thus examined, the result of the whole will now be exhibited in a series of tables, by which the accuracy of the preceding computations will be demonstrated.

Column 1 contains the 1014 years of Censorinus, from Olympiad 1. year 1, to Olympiad CCLIV. year 2.

Column 2, the years of the Julian period, from January 1, 3938, to December 31, 4952.

Columns 3 and 4, the several Olympiads, divided each into four years, and the victors in the stadium.

Column 5, the years of Rome, reckoned backward from the year in which Censorinus wrote, i.e. as he says, the 991st from April 21. By this method it becomes evident that he followed the computation of Varro.

Column 6 exhibits the era of Nabonassar, and the correctness of the computations of Censorinus; for, by astronomical computation, Thoth in the first year began Feb. 26, A.J.P. 3967, and, as Censorinus states, it began in A.J.P. 4952, when he wrote June 20, and that was the 987th year of the æra.

Columns 7 and 8 contain the Julian and Augustan years; and Column 9, the Dionysian or common Christian æra. It began with the last half of the 776th year from the first olympiad. Its first year coincided with the last six months of Olympiad cxciv. 4, and the first six months of Olympiad cxcv. 1, a.j.p. 4714, reformed calendar of Julius Cæsar 46. It was the 29th of the Augustan years, and not the 28th; and thus the only mistake made by Censorinus is detected.

It did not appear necessary to add a separate column for the years of Philip, because they are comprehended in the æra of Nabonassar. In all questions of ancient chronology, it will be required only to add or subtract, as the case may be, 45 for the years of Julius Cæsar, and 4713 of the Julian period, in order to connect the common Christian æra with the various æras in use in ancient times. A little practice will render this easy; and thus, to repeat the language of Petavius, the reader will carry chronology about with him, instead of leaving it to lurk in books and papers.
