In the epic poem "The Odyssey," Odysseus goes into town accompanied by his loyal son Telemachus, his faithful swineherd Eumaeus, and the goddess Athena in disguise.

Athena, the goddess of wisdom, courage, inspiration, civilization, warfare, strength, strategy, female arts, crafts, justice and skill is often accompanied by a Little Owl (Athene noctua).

Athena, the Greek goddess of wisdom and warfare, is often depicted carrying a shield known as the Aegis, which features the head of the Gorgon Medusa. She also typically has a spear, symbolizing her martial prowess and strategic skills. Additionally, she may be shown with an owl, representing wisdom, perched on her shoulder or accompanied by her.
Nike's most common symbol was the palm branch. She was also frequently pictured with Athena and sometimes the goddesses were called Nikai, so Athena's symbols such as the owl and the olive tree sometimes translated to Nike.
