Sejanus was a liar but so fine a general of lies that he knew how to marshal them into an alert and disciplined formation—this was a clever remark of Gallus’s, it is not mine—which would come off best in any skirmish with suspicions or any general engagement with truth. Tiberius envied him this talent as he envied Nerva his honesty: for though he had progressed far in the direction of evil, he still felt hampered by unaccountable impulses towards the good.
