Three is a very mysterious number. It's Poseidon's number.
Thus Poseidon is associated with the number three and carries the trident at all times.
Notice Neptune's main moon is named Triton after Poseidon's son.
This is not just a coincidence. It is one of the many great mysteries hidden in mythology.
According to Plato the gods divided up this earthly realm long ago.
Zeus took the sky.
Hades took the underworld.
Poseidon took the surface of the earth which includes the sea and then used his god like powers to create Atlantis.
This is not just a story. It's true.
