In Virgil's Aeneid, Aeneas encounters a mural depicting battles from the Trojan War, and he is moved to tears and says, "sunt lacrimae rerum et mentem mortalia tangunt" ("There are tears for [or 'of'] things and mortal things touch the mind.") This phrase can be interpreted and translated a number of ways due to the wordplay in Latin, but it seems to touch on the inherent and inevitable sadness of things that occur in life as we each strive for greatness.
