Virgil said this quote
“ Facilis descensus Averno:Noctes atque dies patet atri ianua Ditis;Sed revocare gradium superasque evadere ad auras,Hoc opus, hic labor est.(The gates of Hell are open night and day;Smooth the descent, and easy is the way:But to return, and view the cheerful skies,In this task and mighty labor lies.) ”
