Suetonius,
The Lives of the Twelve Caesars…
“ If ever, therefore, the authority of men the most respectable for virtue, rank, and abilities, could have availed to overawe the first attempts at a violation of public liberty, it must have been at this period; for the dignity of the Roman senate was now in the zenith of its splendour.Cicero has been accused of excessive vanity, and of arrogating to himself an invidious superiority, from his extraordinary talents but whoever peruses his letters to Atticus, must readily acknowledge, that this imputation appears to be destitute of truth. ”
