Poseidon was the god of the seas. From below the waters Poseidon controlled earthquakes, which were a real threat to the Greek lands.

As a result, Poseidon was called the 'Earth Shaker'.

Poseidon was also connected to violent storms and the sea, so Poseidon was thought of as an angry god.

Poseidon was also a lover. He fell in love with the goddesses Medusa and Demeter.

Poseidon was known as Neptune in Roman times.
