From my exposure to Greek mythology (The Iliad, The Odyssey, etc.) I had always seen/heard the god of the sea, Poseidon, referred to as Earth-Shaker. Zeus was always given other titles such as Zeus Cloud-Gatherer or Zeus Thunderer.
However, in the book Moses and Monotheism (p. 74), Sigmund Freud writes:
Zeus still bears the name of "the Earth-shaker."
This seems incorrect to me, as Earth-Shaker seems to be Poseidon's title, not Zeus's title.
A preliminary google search did not return any results for Zeus being referred to as Earth-Shaker. So did Freud simply make a mistake, and use Poseidon's title for Zeus, or are there actually instances where Zeus is referred to as Earth-Shaker?
