WIST

Who kindly sets a wand’rer on his way
Does e’en as if he lit another’s lamp by his:
No less shines his, when he his friend’s hath lit.

[Homo qui erranti comiter monstrat viam,
Quasi lumen de suo lumine accendat facit;
Nihilo minus ipsi lucet, cum illi accenderit.]

Quintus Ennius (239-169 BC) Roman poet, writer
Quoted in Cicero, On Duties [De Officiis], Book 1, ch. 16 [tr. Miller]
