chronology, the eighth month, as the name implies, of the old Roman year, but the tenth in the calendar of Numa, Julius Caesar, &c. The senate gave this month the name of Faustinus, in compliment to Faustina, the wife of the Emperor Antoninus; Commodus wished it to be called Invictus; and Domitian named it Domitianus; but in spite of all these attempts it still retains its original name. This month was sacred to Mars; and a horse, called the October Equus, was annually sacrificed to that deity. A race was run with chariots previously to the sacrifices, when the fleetest horse was made the victim.
