“I think the slain care little if they sleep or rise again.”

Risorgero nemico ognor piu crudo,
Cenere anco sepolto, e spirto ignudo!
Canto IX, stanza 99 (tr. Fairfax)
Gerusalemme Liberata (1581)

Composed in July 1856 this poem is derived from a major passage of the Bhagavad Gita, one of the most popular of Hindu scriptures, and portions of it were likely a paraphrase of an existing translation. Though titled "Brahma" its expressions are actually more indicative of the Hindu concept "Brahman"

Variant: If the red slayer think he slays,
Or if the slain think he is slain,
They know not well the subtle ways
I keep, and pass, and turn again.

The saying "he who fights and runs away may live to fight another day" dates at least as far back as Menander (ca. 341–290 B.C.), Gnomai Monostichoi, aphorism #45: ἀνήρ ὁ ϕɛύγων καὶ ράλίν μαχήɛṯαί (a man who flees will fight again). The Attic Nights (book 17, ch. 21) of Aulus Gellius (ca. 125–180 A.D.) indicates it was already widespread in the second century: "...the orator Demosthenes sought safety in flight from the battlefield, and when he was bitterly taunted with his flight, he jestingly replied in the well-known verse: The man who runs away will fight again".

Context: Do not shorten the morning by getting up late, or waste it in unworthy occupations or in talk; look upon it as the quintessence of life, as to a certain extent sacred. Evening is like old age: we are languid, talkative, silly. Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.

V, lines 1–6
Thomas Campion's translation:
My sweetest Lesbia, let us live and love;
And though the sager sort our deeds reprove,
Let us not weigh them: Heaven's great lamps do dive
Into their west, and straight again revive,
But, soon as once set is our little light,
Then must we sleep one ever-during night.
From A Book of Airs (1601)
Carmina
Context: Let us live, my Lesbia, and love, and value at one farthing all the talk of crabbed old men. Suns may set and rise again. For us, when the short light has once set, remains to be slept the sleep of one unbroken night.
