The moon is a giant lighthouse in the sky. There's even a man living inside who operates it.
What should we do with the drunken sailor, early in the morning?

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)
