Lord Dunsany 
When the Gods Slept [EPUB ebook] 

There in Pegana lay the gods asleep, and in a corner lay the Power of the gods alone upon the floor, a thing wrought of black rock and four words graven upon it, whereof I might not give thee any clue, if even I should find it—four words of which none knoweth. Some say they tell of the opening of a flower towards dawn, and others say they concern earthquakes among hills, and others that they tell of the death of fishes, and others that the words be these: Power, Knowledge, Forgetting, and another word that not the gods themselves may ever guess.
