“Unconscionable Love,
To what extremes will you not drive our hearts!”
Improbe Amor, quid non mortalia pectora cogis!
Compare:
Σχέτλι᾽ Ἔρως, μέγα πῆμα, μέγα στύγος ἀνθρώποισιν,
ἐκ σέθεν οὐλόμεναί τ᾽ ἔριδες στοναχαί τε γόοι τε,
ἄλγεά τ᾽ ἄλλ᾽ ἐπὶ τοῖσιν ἀπείρονα τετρήχασιν.
Unconscionable Love, bane and tormentor of mankind, parent of strife, fountain of tears, source of a thousand ills.
