"...there was no writer, at least in the realm of history, who had not
made some false statement, and even pointed out the places
in which Livy and Sallust, Cornelius Tacitus, and, finally, Trogus could be
refuted by manifest proofs, he came over wholly to my opinion, and,
throwing up his hands, he jestingly said besides: "Well then, write as you will.
You will be safe in saying whatever you wish, since you will have as
comrades in falsehood those authors whom we
admire for the style of their histories."
(Historia Augusta, The Life of Aurelian, 2. 2)
