Note 2 — CICERO AGAINST CATILINE
Reading edition
: ante-Novembres: “on the 12th day before the Kalends of November,” i.e. on October 21st. This anomolous mode of expression probably arose from the transposition of ante. Having one written ante die duodecimo Kalendas, they would easily be led to infer that ante governed die and so would write ante diem duodecimum Kalendas. For the method of computation of time among the Romans, see H. 642.
