Athena

Athena or Athene, often given the epithet Pallas, is an ancient Greek goddess associated with wisdom, handicraft, and warfare who was later syncretized with the Roman goddess Minerva. Athena was regarded as the patron and protectress of various cities across Greece, particularly the city of Athens, from which she most likely received her name. She's usually shown in art wearing a helmet and holding a spear. Her major symbols include owls, olive trees, snakes, and the Gorgoneion.
In Greek mythology, Athena was believed to have been born from the head of her father Zeus. In the founding myth of Athens, Athena bested Poseidon in a competition over patronage of the city by creating the first olive tree.
Athena was the patron goddess of heroic endeavor; she's believed to have aided the heroes Perseus, Heracles, Bellerophon, and Jason. Along with Aphrodite and Hera, Athena was one of the three goddesses whose feud resulted in the beginning of the Trojan War. She plays an active role in the Iliad, in which she assists the Achaeans and, in the Odyssey, she is the divine counselor to Odysseus.
In the later writings of the Roman poet Ovid, Athena was said to have competed against the mortal Arachne in a weaving competition, afterwards transforming Arachne into the first spider; Ovid also describes how she transformed Medusa into a Gorgon after witnessing her being violated by Poseidon in her temple. Since the Renaissance, Athena has become an international symbol of wisdom, the arts, and classical learning. Western artists and allegorists have often used Athena as a symbol of freedom and democracy.
In the classical Olympian pantheon, Athena was regarded as the favorite daughter of Zeus, born fully armed from his forehead. The story of her birth comes in several versions. The earliest mention is in the Iliad, when Ares accuses Zeus of being biased in favor of Athena because "autos egeinao" (literally "you fathered her", but probably intended as "you gave birth to her").
Zeus married the goddess Metis, who is described as the "wisest among gods and mortal men", and engaged in sexual intercourse with her. After learning that Metis was pregnant, however, he became afraid that the unborn offspring would try to overthrow him, because Gaia and Ouranos had prophesied that Metis would bear children wiser than their father. In order to prevent this, Zeus tricked Metis into letting him swallow her, but it was too late because Metis had already conceived.
After swallowing Metis, Zeus took six more wives in succession until he married his seventh and present wife, Hera. Then Zeus experienced an enormous headache. He was in such pain that he ordered someone (either Prometheus, Hephaestus, Hermes, Ares, or Palaemon, depending on the sources examined) to cleave his head open with the labrys, the double-headed Minoan axe. Athena leaped from Zeus's head, fully grown and armed.The "First Homeric Hymn to Athena" states in that the gods were awestruck by Athena's appearance and even Helios, the god of the sun, stopped his chariot in the sky. Pindar, in his "Seventh Olympian Ode", states that she "cried aloud with a mighty shout" and that "the Sky and mother Earth shuddered before her.
Athena competed with Poseidon for the patronage of Athens. They agreed that each would give the Athenians one gift and that Cecrops, the king of Athens, would determine which gift was better. Poseidon struck the ground with his trident and a salt water spring sprang up; this gave the Athenians access to trade and water. Athens at its height was a significant sea power, defeating the Persian fleet at the Battle of Salamis--but the water was salty and undrinkable. Athena offered the first domesticated olive tree. Cecrops accepted this gift and declared Athena the patron goddess of Athens. The olive tree brought wood, oil, and food, and became a symbol of Athenian economic prosperity.
According to Pseudo-Apollodorus's Bibliotheca, Athena advised Argos, the builder of the Argo, the ship on which the hero Jason and his band of Argonauts sailed, and aided in the ship's construction. Pseudo-Apollodorus also records that Athena guided the hero Perseus in his quest to behead Medusa.She and Hermes, the god of travelers, appeared to Perseus after he set off on his quest and gifted him with tools he would need to kill the Gorgon. Athena gave Perseus a polished bronze shield to view Medusa's reflection rather than looking at her directly and thereby avoid being turned to stone. Hermes gave him an adamantine scythe to cut off Medusa's head. When Perseus swung his blade to behead Medusa, Athena guided it, allowing his scythe to cut it clean off.
In Aeschylus's tragedy Orestes, Athena intervenes to save Orestes from the wrath of the Erinyes and presides over his trial for the murder of his mother Clytemnestra. When half the jury votes to acquit and the other half votes to convict, Athena casts the deciding vote to acquit Orestes and declares that, from then on, whenever a jury is tied, the defendant shall always be acquitted.
In The Odyssey, Odysseus' cunning and shrewd nature quickly wins Athena's favor. For the first part of the poem, however, she largely is confined to aiding him only from afar, mainly by implanting thoughts in his head during his journey home from Troy. Her guiding actions reinforce her role as the "protectress of heroes," or, as mythologian Walter Friedrich Otto dubbed her, the "goddess of nearness," due to her mentoring and motherly probing.
It is not until he washes up on the shore of the island of the Phaeacians, where Nausicaa is washing her clothes that Athena arrives personally to provide more tangible assistance. She appears in Nausicaa's dreams to ensure that the princess rescues Odysseus and plays a role in his eventual escort to Ithaca. Athena appears to Odysseus upon his arrival, disguised as a herdsman; she initially lies and tells him that Penelope, his wife, has remarried and that he is believed to be dead, but Odysseus lies back to her, employing skillful prevarications to protect himself. Impressed by his resolve and shrewdness, she reveals herself and tells him what he needs to know in order to win back his kingdom. She disguises him as an elderly beggar so that he will not be recognized by the suitors or Penelope, and helps him to defeat the suitors. Athena also appears to Odysseus's son Telemachus. Her actions lead him to travel around to Odysseus's comrades and ask about his father. He hears stories about some of Odysseus's journey. Athena's push for Telemachos's journey helps him grow into the man role, that his father once held. She also plays a role in ending the resultant feud against the suitors' relatives.
According to Ovid, Arachne (whose name means spider in ancient Greek) a weaving student of Athena. She became so conceited of her skill as a weaver that she began claiming that her skill was greater than that of Athena herself. Athena gave Arachne a chance to redeem herself by assuming the form of an old woman and warning Arachne not to offend the deities. Arachne scoffed and wished for a weaving contest, so she could prove her skill.
Athena wove the scene of her victory over Poseidon in the contest for the patronage of Athens. Athena's tapestry also depicted the 12 Olympian gods and defeat of mythological figures who challenged their authority. Arachne's tapestry featured twenty-one episodes of the deities' infidelity. It represented the unjust and discrediting behavior of the gods towards mortals. Athena admitted that Arachne's work was flawless, but was outraged at Arachne's offensive choice of subject, which displayed the failings and transgressions of the deities. Finally, losing her temper, Athena destroyed Arachne's tapestry and loom, striking it with her shuttle. Athena then struck Arachne across the face with her staff four times. Arachne died in despair, but Athena took pity on her and brought her back from the dead in the form of a spider.
The myth of the Judgement of Paris is mentioned briefly in the Iliad, but is described in depth in an epitome of the Cypria, a lost poem of the Epic Cycle, which records that all the gods and goddesses as well as various mortals were invited to the marriage of Peleus and Thetis (the eventual parents of Achilles). Only Eris, goddess of discord, was not invited. She was annoyed at this, so she arrived with a golden apple inscribed with the word καλλίστῃ ("for the fairest"), which she threw among the goddesses. Aphrodite, Hera, and Athena all claimed to be the fairest, and thus the rightful owner of the apple.
The goddesses chose to place the matter before Zeus, who, not wanting to favor one of the goddesses, put the choice into the hands of Paris, a Trojan prince. After bathing in the spring of Mount Ida where Troy was situated, the goddesses appeared before Paris for his decision.
All three goddesses were ideally beautiful and Paris could not decide between them, so they resorted to bribes. Hera tried to bribe Paris with power over all Asia and Europe, and Athena offered fame and glory in battle, but Aphrodite promised Paris that, if he were to choose her as the fairest, she would let him marry the most beautiful woman on Earth. This woman was Helen, who was already married to King Menelaus of Sparta. Paris selected Aphrodite and awarded her the apple. The other two goddesses were enraged and, as a direct result, sided with the Greeks in the Trojan War
