Abstract Nº 21

Facilis descensus Averni:
noctes atque dies patet atri ianua Ditis;
sed revocare gradium superasque evadere ad auras.
hoc opus, hic labor est.

(It is easy to go down into Hell;
Night and day, the gates of dark Death stand wide;
But to climb back again, to retrace one's steps to the upper air,
There's the rub, the task.)

Virgil, "The Aeneid", Book VI.
