The Fasti Triumphales record the celebration of the triumph of Ti. Sempronius Gracchus on the Terminalia of this year. Michels' proposal is that such dates are only used in intercalary years; her argument is accepted by P. Brind'Amour,

Le calendrier romain, 150.It is held here that such dates indicate a candidate intercalary year. Under the reconstructed

Lex Aciliaproposed here, it follows that A.U.C. 578 = 176 was not 378 days long, and hence that A.U.C. 577 = 177 was not 377 days long. Since that year was intercalary it must then have been 378 days long, implying that A.U.C. 578 = 176 was a regular year. Since there were no pairs of consecutive regular years in this period, it follows that this year was intercalary, though its length cannot be determined.We can proceed further under the proposed

Lex Acilia. Since this year was intercalary, A.U.C. 582 = 172 was 378 days long, and there were no pairs of consecutive regular years between A.U.C. 564 = 190 and A.U.C 586 = 168, the years between A.U.C. 578 = 176 and A.U.C. 582 = 172 must be 377, 378 and 355 days long, or 378, 355 and 377 days long. Either way, the period was 1,110 days long. This fixes the Julian dates of A.U.C. 579 = 175.Website © Chris Bennett, 2001-2011 -- All rights reserved
