The Protector

Lore & Background

Homer reports that Poseidon became lord of the sea when, following the overthrow of his father Cronus, the world was divided by lot among Cronus' three sons; Zeus received the sky, Hades the underworld, and Poseidon the sea, with the Earth and Mount Olympus belonging to all three. In Plato's Timaeus and Critias, the legendary island of Atlantis was Poseidon's domain. In Homer's Iliad, Poseidon supports the Greeks against the Trojans during the Trojan War. In the Odyssey, during the sea-voyage from Troy back home to Ithaca, the Greek hero Odysseus provokes Poseidon's fury by blinding his son, the Cyclops Polyphemus, resulting in Poseidon punishing him with storms, causing the complete loss of his ship and numerous of his companions, and delaying his return by ten years. According to legend, Athena became the patron goddess of the city of Athens after a competition with Poseidon, though he remained on the Acropolis in the form of his surrogate, Erechtheus. After the fight, Poseidon sent a monstrous flood to the Attic plain to punish the Athenians for not choosing him.

In Their Own Story

During the Mycenean period, the ancestral male gods of the Myceneans were probably not represented in human forms, and the information given by the tablets found at Pylos and Knossos is insufficient. Poseidon was the chief deity at Pylos and Thebes. He is identified with Anax and he carried the title "Master of the Underworld". Anax had probably a cult associated with the protection of the palace. In Acrocorinth he was worshipped as Poseidon Anax during the Mycenean age. In the city, there was the famous spring Peirene, which in a myth is related to the winged horse Pegasus. In Attica there was a cult of Anax heroes who was connected to Poseidon. A cult title of Poseidon was "earth-shaker" and in Knossos he was worshipped together with the goddess Eleithyia who was related to the annual birth of the divine child. Potnia was the Mycenean goddess of nature and she was the consort of Poseidon at Pylos. She is mentioned together with bucrania in decorated jugs and he was associated with the animals and especially to the bull. In Athens, Poseidon was an inland god who created the salt-sea Erecthēιs (Ερεχθηίς), "sea of Erechtheus". In Acropolis his cult was superimposed on the cult of the local ancestral figure Erechtheus. In Athens and Asine he was worshipped in the house of the king during the Mycenean period. The bull was the favourite animal for sacrifices and it seems that horses were rarely used during the burial of the Mycenean leaders.

In the Arcadian myths, Poseidon is related to Demeter and Despoina and he was worshipped with the surname Hippios in many Arcadian cities. At Thelpusa and Phigalia there were sister worships which are very important for the study of primitive religions. In these cults Demeter and Poseidon were chthonic divinities of the underworld. Near Thelpusa the river Ladon descended to the sanctuary of Demeter Erinys (Demeter-Fury). During her wandering in search of her daughter Demeter changed into a mare to avoid Poseidon. Poseidon took the form of a stallion and after their mating she gave birth to a daughter whose name was not allowed to be told to the uninitiated and a horse called Arion (very swift). Her daughter obviously had the shape of a mare too. At first Demeter became angry and she was given the surname Erinys (fury) by the Thelpusians. The Erinyes were deities of vengeance, and Erinys had a similar function with the goddess Dike (Justice). In the very old myth of Thelpusa Demeter-Erinys and Poseidon are divinities of the underworld in a pre-mythic period. Poseidon appears as a horse. In Greek folklore the horses had chthonic associations and it was believed that they could create springs. In European folklore the water-creatures or water-spirits appear with the shape of a horse or a bull. In Greece the river god Acheloos is represented like a bull or a man-bull. Many people when sacrificed to Demeter should make a premilinary sacrifice to Acheloos. At Phigalia Demeter had a sanctuary in a cavern and she was given the surname Melaina (black). The goddess was related to the black underworld. In a similar myth Poseidon appears as a horse and Demeter gives birth to a daughter whose name was not allowed to be told to the unitiated (At Lycosura her daughter was called Despoina). Demeter, angry with Poseidon, put on a black dressing and shut herself in the cavern. When the fruits of the earth were perished, Zeus sent the Moirai to Demeter who listened to them and put aside he
