Gaius Suetonius Tranquillus,
The Lives of the Twelve Caesars…
“ The emperor Aulus Vitellius, son of Lucius, was born on the eighth day before the Kalends of October, or according to some, on the seventh day before the Ides of September, in the consulship of Drusus Caesar and Norbanus Flaccus. His parents were so aghast at his horoscope as announced by the astrologers, that his father tries his utmost, while he lived, to prevent the assignment of any province to his son; and when he was sent to the legions and hailed as emperor, his mother immediately mourned over him as lost. ”
