(it's from Time and the Gods by Lord Dunsany)
"Slay him not, for it is not enough that Althazar shall die, who hath made the faces of the gods to be like the faces of men, but he must not even have ever been."
Then said the gods:
"Spake we of Althazar, a King?"
And the gods said:
"Nay, we spake not." And the gods said:
"Dreamed we of one Althazar?" And the gods said:
"Nay, we dreamed not."
But in the royal palace of Runazar, Althazar, passing suddenly out of the remembrance of the gods, became no longer a thing that was or had ever been.
