Suetonius,
The Lives of the Twelve Caesars…
“ If we view Domitian in the different lights in which he is represented, during his lifetime and after his decease, his character and conduct discover a greater diversity than is commonly observed in the objects of historical detail. But as posthumous character is always the most just, its decisive verdict affords the surest criterion by which this variegated emperor must be estimated by impartial posterity. ”
