The Devil's Dictionary (1881-1906):

ZEUS, n.  The chief of Grecian gods, adored by the Romans as Jupiter
and by the modern Americans as God, Gold, Mob and Dog.  Some explorers
who have touched upon the shores of America, and one who professes to
have penetrated a considerable distance to the interior, have thought
that these four names stand for as many distinct deities, but in his
monumental work on Surviving Faiths, Frumpp insists that the natives
are monotheists, each having no other god than himself, whom he
worships under many sacred names.
