"Unus valde fallit conari extrahunt uirtutibus quisque non habet, omisso cultu quas habet." ["One great mistake is to try to extract from each person virtues which he does not possess, neglecting the cultivation of those which he does have."] -- Hadrian (b. 76-01-24, d. 138-07-10, reigned 117-08-10 to 138-07-10)
 Caesar Publius Aelius Traianus Hadrianus Buccellanus Augustus, né Publius Aelius Hadrianus Buccellanus.
 I only found a few sites repeating this quotation on the web, and all but one of those looked as though they'd all gotten it from the same place. The remaining site was the only one that had the Latin. So I'm not entirely certain that this isn't from some later work about Hadrian, or just plain misattributed. Can any of y'all nail down whether it's authentic or not?
 Y'know, like that famous line Voltaire never said, that a biographer said was the kind of thing he'd say, but everybody just associates with Voltaire anyhow. I imagine that sort of thing happens a lot.
