Difference Between Poseidon and Neptune (With Table)

Poseidon vs Neptune

Greek mythology and Roman mythology have always impacted our existing knowledge greatly. Whether it is their writings and principles or their lifestyle, they are believed to be a huge influence on what we are today. If you believe in the revival of history, you cannot help but go through the pages of Roman and Greek origin.

Gods of either mythology are still taken care of in contemporary writings. Today we are going to understand and differentiate amongst two of the greatest Gods of the Roman and Greek culture: Neptune, the God of freshwater, and Poseidon, the great God of the sea.

Although the two Gods might seem to rule the sea, there is a giant difference in their rule, their origin, their culture and their stories. They have their own history to begin with and no way it is possible for the separate histories to collide and merge to be one. Neptune is the Roman God of freshwater and Poseidon is the Greek God of the sea and in no way are these two Gods the same.

It is a myth often heard that Romans adopted the great God of the sea, Poseidon, and very feasibly renamed him Neptune. However, this isn’t true at all!

Even though Poseidon and Neptune appear to look almost the same, there is a gigantic history separating them, originating from their respective geographical land.

The difference between Poseidon and Neptune is that Poseidon is the Greek God of the sea and Neptune is the Roman God of freshwater, who is often seen in pictures riding a seahorse. He is believed to have reproduced seahorses with Medusa (one of the three monstrous Gorgons in Greek mythology). Even though the two appear to have strikingly similar features in sculptures, their history and origin separate them clearly. They belong to two absolutely unique culture.

The festival was orchestrated in the middle of summer, 23rd of July when Greece was struck with water scarcity. Since Neptune is believed to be the God of freshwater, the deity was appealed and invocated for the crisis. Neptune is also believed to have a temple in his name in Rome called Circus Flaminius.
