"Let fools seek it. They shall win it not. For although my treasure house be empty as air, no deadly creature in rocky lair, no sentinel outside anywhere, no pitfall, poison, trap, or snare, above and below the whole place bare, of demon or devil not a hair, no serpent lethal-fanged yet fair, no skull with mortal eye a-glare, yet have I left a guardian there. Let the wise read this riddle and forbear."
