Eusebius figures are incorrect. He omits Vitellius entirely, while he stretches Galba’s and Otho’s reigns to make them cover a period of eighteen months, instead of nine (Galba reigned from June 9, 68, to Jan. 15, 69; and Otho from Jan. 15 to April 20, 69). The total of the three reigns of Galba, Otho, and Vitellius was about eighteen months.
