Sea goddess and consort of Poseidon
Amphitrite is the personification of the sea. She was first a sea nerid and then because of her marriage to Poseidon she became known as a sea goddess.
In Greek mythology, Amphitrite goddess of the sea was one of the fifty Nereids, that is a daughter of Nereus and Doris - that's what Hesiod writes in his Theogony (but Apollodorus says her parents were Oceanus and Thetys). Her Roman equivalent was Salacia, god Neptune's wife. Her name means "The third one who encircles (everything)" (because the ancient Greeks thought the whole world was encircled by a river-god, Oceanus). She spent most of the time singing and dancing with her sisters. One day Poseidon, god of the sea saw her near the island of Naxos and fell in love with her. He kidnapped her and made her his wife. In another story, Amphitrite, being a shy girl, fled away and hid somewhere in the Atlantic Ocean. Poseidon wanted desperately to find her, so he sent all the marine creatures to look for her. Delphinus, a dolphin, managed to find her and convinced her to go back to Poseidon and marry him. That's what made Amphitrite goddess of the sea. (By the way, the dolphin who found her was turned into a constellation by the grateful Poseidon).
Although Amphitrite is essentially represented as a female version of Poseidon, their abilities as gods differ greatly. While Poseidon can conjure up storms, produce earthquakes, control the sea and more, Amphitrite has much less abilities. In fact, she may not have any abilities that are similar to Poseidon’s, in the sense that they are supernatural. However, it is shown that she has a great knowledge of herbs, because she uses a special kind of herb on one of her rivals that transforms her into a hideous monster. So although she does not have any powers such as Poseidon, she makes up for them with her knowledge of herbs and other things.
Although Amphitrite was a kind person, she was also extremely jealous and vengeful. When Poseidon first married Amphitrite, he thought he was in love, unlike his usual womanizing ways of simply being physically attracted to someone. However, eventually he went back to his old ways, and this made Amphitrite extremely jealous and upset. There are countless stories of her vengeance on those who Poseidon fancied, but the most famous is against a woman named Scylla. When Poseidon showed that he was attracted to her, Amphitrite became so jealous that she threw a special type of herb into the well where Scylla bathed, which caused her to transform into a hideous monster. This monster was put on a cliff to snatch sailors off of their ships for meals, which caused this monster to be feared by many sailors everywhere.
She also appeared briefly in the story of Theseus. King Minos asked the hero to prove that he really was Poseidon's son. A ring was thrown into the sea and Theseus had to bring it back. The sea creatures found the ring and gave it to the hero, while Amphitrite goddess of the sea received him in her underwater palace and gave him a golden crown, which he took to Ariadne as a wedding gift. Amphitrite and Poseidon had a son, Triton (a fish-man or a he-mermaid) and a daughter, Rhode, and maybe another daughter, Benthesicyme.
Kind - Amphitrite is probably the only goddess without a fiery temper. She is kind to all whom she feels need assistance. The young goddess have never really been on to intimidate others in any way. However, being a nymph, she does have quite an allure about her.
Stubborn - Though she rarely makes a decision, those decisions are never changeable. She is incredibly stubborn. She is very opinionated, though perhaps takes a moment to decide her own opinion. She looks at all sides of the arguement.
Sacred Symbols and Animals
Chariot - In mosaic art the goddess usually rides beside her husband in a chariot drawn by fish-tailed horses or hippokampoi.
Net - Sometimes her hair is enclosed with a net and her brow adorned with a pair of crab-claw "horns".
Dolphin - Delphinus, a dolphin, managed to find her and convinced her to go back to Poseidon and marry him. That's what made Amphitrite goddess of the sea. (By the way, the dolphin who found her was turned into a constellation by the grateful Poseidon).
