Plutarch, Quomodo adulator ab amico internoscatur
Goodwin, Ed.

But there are others behind, who outdo all the subtlety of the former, such as can claw and please, even whilst they seem to reprehend. Thus when Alexander had bestowed some considerable reward upon a jester, Agis the Argive, through mere envy and vexation, cried out upon it as a most absurd action; which the king overhearing, he turned him about in great indignation at the insolence, saying, What's that you prate, sirrah? Why truly, replied the man, I must confess, I am not a little troubled to observe, that all you great men who are descended [p. 126] from Jupiter take a strange delight in flatterers and buffoons; for as Hercules had his Cercopians and Bacchus his Silenuses about him, so I see your majesty is pleased to have a regard for such pleasant fellows too. And one time when Tiberius Caesar was present at the senate, there stood up a certain fawning counsellor, asserting that all free-born subjects ought to have the liberty of speaking their sense freely, and should not dissemble or conceal any thing that they might conceive beneficial to the public; who, having thus awakened the attention of his audience, silence being made, and Tiberius impatient to hear the sequel of the man's discourse, pursued it in this manner: I must tell you of a fault, Caesar, said he, for which we universally blame you, though no man yet has taken the confidence to speak it openly. You neglect yourself, endanger your sacred person by your too much labor and care, night and day, for the public. And he having harangued several things to the same effect, it is reported that Cassius Severus the orator subjoined: This man's freedom of speech will ruin him.
