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 is usually shown in art wearing a helmet and holding a spear. Her major symbols include owls, olive trees, snakes, and the Gorgoneion.
From her origin as an Aegean palace goddess, Athena was closely associated with the city. She was known as Polias and Poliouchos (both derived from polis, meaning "city-state"), and her temples were usually located atop the fortified Acropolis in the central part of the city. The Parthenon on the Athenian Acropolis is dedicated to her, along with numerous other temples and monuments. As the patron of craft and weaving, Athena was known as Ergane. She was also a warrior goddess, and was believed to lead soldiers into battle as Athena Promachos. Her main festival in Athens was the Panathenaia, which was celebrated during the month of Hekatombaion in midsummer and was the most important festival on the Athenian calendar.
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. She was known as Athena Parthenos ("Athena the Virgin"), but, in one archaic Attic myth, the god Hephaestus tried and failed to rape her, resulting in Gaia giving birth to Erichthonius, an important Athenian founding hero. Athena was the patron goddess of heroic endeavor; she was believed to have also 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.
Athena is associated with the city of Athens. The name of the city in ancient Greek is Ἀθῆναι (Athenai), a plural toponym, designating the place where—according to myth—she presided over the Athenai, a sisterhood devoted to her worship. In ancient times, scholars argued whether Athena was named after Athens or Athens after Athena.
This is she who has the mind of God [ἁ θεονόα, a theonóa). Perhaps, however, the name Theonoe may mean "she who knows divine things" [τὰ θεῖα νοοῦσα, ta theia noousa] better than others. Nor shall we be far wrong in supposing that the author of it wished to identify this Goddess with moral intelligence [εν έθει νόεσιν, en éthei nóesin], and therefore gave her the name Etheonoe; which, however, either he or his successors have altered into what they thought a nicer form, and called her Athena.
Thus, Plato believed that Athena's name was derived from Greek Ἀθεονόα, Atheonóa—which the later Greeks rationalised as from the deity's (θεός, theós) mind (νοῦς, noũs). The second-century AD orator Aelius Aristides attempted to derive natural symbols from the etymological roots of Athena's names to be aether, air, earth, and moon.
