||In the ancient Greek religion, Zeus is the "Father of Gods and men" (πατὴρ ἀνδρῶν τε θεῶν τε, patḕr andrōn te theōn te) who rules the Olympians of Mount Olympus as a father rules the family. He is the god of sky and thunder

|Origin ||Poseidon was a son of Cronus and Rhea. In most accounts he is swallowed by Cronus at birth but later saved, with his other brothers and sisters, by Zeus.
||Like other children of Cronus and Rhea, Cronus wanted to swallow Zeus at birth. But when Rhea gave birth to Zeus in Crete, she handed Cronus a rock wrapped in swaddling clothes, which he promptly swallowed.
