Neptune

Neptune is the Roman Counterpart of Poseidon. As Neptune, he becomes more disciplined, militaristic and warlike. For Greeks he was a major civic God and was highly respected for being the God of Sea and Earthquakes but the Romans, who were not seafaring people, associated him more with Fresh Water and Horses. The planet Neptune was named after him. He is mentioned several times during The Son Of Neptune.

He is highly feared at Camp Jupiter and only has a toolshed as a temple. In 1906, his descendant Shen Lun was blamed for the earthquake and was banished from the Camp.

History
The Romans believed in a series of gods associated with world around them. They designated Neptune the god of water and the sea, a close parallel to the Greek god Poseidon.

As a god of both fresh water and the sea, Romans prayed to Neptune to provide water for their crops. In ancient Italy, farmers would honor Neptune with a festival in July, when frequent droughts would destroy their fields. He was also a patron of horses and had a temple called Circus Flaminius built near a race track, and another in Campus Martius.

The planet Neptune was named after the god, as its deep blue gas clouds gave the earliest astronomers the impression of great oceans and seas. He was also the patron of horse racing and a temple dedicated to him was situated near the Circus Flaminius which was a Roman racetrack. The Circus Flaminius was the venue for horse, not chariot, races with one rider and his horse going around the turning posts. In the famous story of the Aeneid, Neptune was resentful towards the Trojans, but is not as vindictive as Juno. He was so annoyed that Juno had intruded on his domain that he helped the Trojan fleet against the efforts of Juno who tried the wreck their ships.
