“Surely it isn’t better when every truth bares its real face.”
οὔ τοι ἅπασα κερδίων
φαίνοισα πρόσωπον ἀλάθει’ ἀτρεκές·
ΕΥΔΟΞΑ ΑΓΝΩΣΤΑ ΚΑΤΑΓΕΛΑΣΤΑ
“It is not shameful to proclaim even a lie publicly to save a life.”
οὐ νέμεσις καὶ ψεῦδος ὑπὲρ ψυχῆς ἀγορεύειν.
Peisander, you ask? Not the Spartan general or the Severan era poet.
(An epic poet, perhaps?)
“I would rather serve as slave to another man
a man with no land and livelihood
than be a king over all the rotted corpses”
βουλοίμην κ’ ἐπάρουρος ἐὼν θητευέμεν ἄλλῳ,
ἀνδρὶ παρ’ ἀκλήρῳ, ᾧ μὴ βίοτος πολὺς εἴη,
ἢ πᾶσιν νεκύεσσι καταφθιμένοισιν ἀνάσσειν.
Achilles’ words to Odysseus (according, of course, to Odysseus)

“There is a good time for lies and god honors it”
ψευδῶν δὲ καιρὸν ἔσθ’ ὅπου τιμᾷ θεός
Aeschylus was considered old-fashioned and austere, even among the Ancient Athenians!
“I think that the story of Odysseus’ suffering was exaggerated by sweet-worded Homer”
λόγον ᾿Οδυσσέος ἢ πάθαν
διὰ τὸν ἁδυεπῆ γενέσθ’ ῞Ομηρον·
Pindar was a poet of Epinikion.
(but this line doesn’t seem to be about praise… for Homer, at least)
