Varro may have used the consular list (with its mistakes) and called the year of the first consuls "''ab Urbe condita'' 245," accepting the 244-year interval from Dionysius of Halicarnassus for the kings after the foundation of Rome.

AD 41 to AD 54) onward, this calculation superseded other contemporary calculations. Celebrating the anniversary of the city became part of imperial propaganda. Claudius was the first to hold magnificent celebrations in honor of the anniversary of the city, in AD 48, the eight hundredth year from the founding of the city. Hadrian, in AD 121, and
