Ἐχθρὸς γάρ μοι κεῖνος ὁμῶς Ἀΐδαο πύλῃσιν
ὅς χ' ἕτερον μὲν κεύθῃ ἐνὶ φρεσίν, ἄλλο δὲ εἴπῃ.
Who dares think one thing, and another tell,
My heart detests him as the gates of hell.
IX. 312–313 (tr. Alexander Pope)
Hateful to me as the gates of Hades is the man who hides one thing in his heart and speaks another.
A. H. Chase and W. G. Perry, Jr.'s translation
