Zeus (Marvel)
From Multiversal Omnipedia
Zeus was the fierce, red-bearded leader of the gods of Olympus. His frustrations with the actions of his son Hercules have led to several banishments and punishments over time.
Comments
Conan the Barbarian I#79-81 would indicate that Zeus was not worshipped in the Hyborian Age, since Conan did not recognize his name when descedants of time-travellers mentioned him.
Neptune was worshipped, per Namor I#38, as early as 5800 BCE.
