Afterwards the fifth month was named Julius, from Julius Caesar, the conqueror of Pompey; and the sixth month Augustus, from the second Caesar, who was given that title. The seventh and eighth months bore for a short time the names Germanicus and Domitianus, which the emperor Domitian gave them; but when he was slain, they resumed their old names of September and October. Only the last two months, November and December, preserved the names derived from their position in the list just as they were at the outset.
