Except for two incidents.
Zeus had promised Persephone as a wedding present to give her one wish. How would anyone guess that she would wish for six months each year with her mother! Dreadful mistake, that wedding present. Zeus was a bit muddled, plainly, when he let himself be cajoled into such a promise.
The other incident hadn't been quite that bad.
Ceres came forward to give him her blessing.
She wiped the tears from her eyes, looked straight at him, and intoned slowly - "One born of man shall aid her, and when you follow him it will be to a foreordained destiny."
That was all. She smiled, turned away, and left the wedding party.
He had brooded long over her words.
Zeus knew not of their content, or refused to divulge his knowledge.
She was his bride, this his kingdom, and the only earthlings were those poor souls whose lifely habits had condemned them to his control.
Pluto, Ruler of Hades, to fear nothing.
