Space used in the times of Poseidon resembled Classical Greek Architecture. The Parthenon is a perfect example. From the elegantly simple yet refined Doric columns, to the elaborately beautiful images of sculpture (which were designed by the famous artist Phidias) that adorn the frieze, metopes, and pediments, this structure perfectly embodies the Classical Greek ideals of order, harmony, and balance.
On the first day of spring, Greeks sail out to sea and sacrifice horses by drowning them to honor Poseidon. Sailors relied on a pacified Poseidon for a safe voyage on the sea. When he was in a good mood, Poseidon created new lands in the water and a calm sea. In contrast, when he was in a bad mood, Poseidon would strike the ground with a trident and cause unruly springs and earthquakes, ship wrecks, and drownings.
If Poseidon wasn’t pleased with the amount of horses sacrificed he would unleash his terrible temper. Countless cities would be flooded. After the cities recovered Poseidon would let loose a sea monster for more terrible destruction. For the grand finale he would strike the ground with his huge trident that would cause a destructive earthquake throughout Greece.
