Plutarch
Plutarch. Moralia, Vol. III. Babbitt, Frank Cole, translator. Cambridge, MA: Harvard University Press; London: William Heinemann Ltd., 1931 (printing).
When Hermodotus in his poems wrote of him as The Offspring of the Sun, he said, The slave who attends to my chamber-pot is not conscious of that! [*](Cf. Moralia, 360 C.)
When somebody remarked that all things are honourable and righteous for kings, he said, Yes indeed, for kings of the barbarians; but for me only the honourable things are honourable and the righteous righteous.
