Minerva /mɪˈnɜːrvə/ (Latin: [mɪˈnɛrwa]; Etruscan: Menrva) is the Roman goddess of wisdom and strategic warfare, justice, law, victory, and the sponsor of arts, trade, and strategy. Minerva is not a patron of violence such as Mars, but of defensive war only. From the second century BC onward, the Romans equated her with the Greek goddess Athena. Minerva is one of the three Roman deities in the Capitoline Triad, along with Jupiter and Juno.

She was the virgin goddess of music, poetry, medicine, wisdom, commerce, weaving, and the crafts. She is often depicted with her sacred creature, an owl usually named as the "owl of Minerva", which symbolised her association with wisdom and knowledge as well as, less frequently, the snake and the olive tree. Minerva is commonly depicted as tall with an athletic and muscular build, as well as wearing armour and carrying a spear. As the most important Roman goddess, she is highly revered, honored, and respected.

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. The Parthenon on the Acropolis of Athens is dedicated to her. Her major symbols include owls, olive trees, snakes, and the Gorgoneion. In art, she is generally depicted wearing a helmet and holding a spear.

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 forehead 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 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, afterward transforming Arachne into the first spider; Ovid also describes how she transformed Medusa into a Gorgon after witnessing her being raped 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.
