Quem di diligent, adolescens moritur, dum valet, sentit, sapit.
He whom the gods protect : the youth is dying whilst he is in health, and has his senses and his judgment sound.
Bacchides Act IV, scene 7, line 18.
Variant translation: He whom the gods love dies young. (translator unknown)
Derived from Menander's The Double Deceiver; but only the Plautine version was known until the rediscovery of Menander in the 20th century; sometimes translated as "favor" instead of "love".
