Poseidon
- "Poseidon, god of the ocean. Thank you for watching over the Adrestia."
- ―Misthios Kassandra, beholding a statue of the god, around 431 BCE

Poseidon, known to the Romans as Neptune, is the Greek god of the seas and the ocean, horses and earthquakes.
He is regarded as one of the Twelve Olympians, the major deities of the Greek pantheon as well as the brother of Pluto.[1] Additionally, Poseidon was also rumoured to have fathered Byzas with the nymph Keroessa. Byzas later became the founder of Byzantium, which later came to be known as Constantinople.[2]
Amphitrite, wife of Poseidon and queen of the sea, was said to have birthed his other son Triton, who had a conch shell to control the sea. [citation needed]
C. 431 BCE, during the height of the Peloponnesian War, the misthios Kassandra obtained Poseidon's Trident within the ruins of a temple to his name. This trident was an Isu artefact attributed to Poseidon that allowed the wielder to breath underwater and was said to "control the seas".[3]
In 48 BCE, Poseidon was mentioned by Phoxidas during his time defending the Egyptian seas with Aya.[4]
