He argued that Caesar would have enforced the bissextile day by introducing it in his first reformed year. T. E. Mommsen, Die Römische Chronologie bis auf Caesar (Berlin, 1859) 282-299, provided additional circumstantial arguments.
^ H. Matzat, Römische Chronologie I (Berlin, 1883), 13-18. His argument rested on Dio Cassius 48.33.4 which mentions a leap day inserted in 41 BC, "contrary to the (i.e. Caesar's) rule", in order to avoid having a market day on the first day of 40 BC. Dio stated that this leap day was compensated "later". Matzat proposed this was done by omitting a scheduled leap day in 40 BC, rather than by omitting a day from an ordinary year.
^ W. Soltau, Römische Chronologie (Freiburg, 1889) 170-173. He accepted Matzat's phase of the triennial cycle but argued that it was absurd to suppose that Caesar would have made the second Julian year a leap year and that the 36 years had to be accounted from 45 BC.
