Lord Dunsany 
The Gods of Pegana [EPUB ebook] 

Before there stood gods upon Olympus, or ever Allah was Allah, had wrought and rested MANA-YOOD-SUSHAI.
There are in Pegana Mung and Sish and Kib, and the maker of all small gods, who is MANA-YOOD-SUSHAI. Moreover, we have a faith in Roon and Slid.
And it has been said of old that all things that have been were wrought by the small gods, excepting only MANA-YOOD-SUSHAI, who made the gods and hath thereafter rested.
And none may pray to MANA-YOOD-SUSHAI but only the gods whom he hath made.
But at the Last will MANA-YOOD-SUSHAI forget to rest, and will make again new gods and other worlds, and will destroy the gods whom he hath made.
And the gods and the worlds shall depart, and there shall be only
MANA-YOOD-SUSHAI.
