“Now dim to one another
In desolate night they walked on through the gloom,
Through Dis’s homes all void, and empty realms,
As one goes through a wood by a faint moon’s
Treacherous light, when Jupiter veils the sky
And black night blots the colors of the world.”

—Virgil, The Aeneid, between 29 and 19 BCE, translated by Robert Fitzgerald, 1983.
