The animal considered a symbol of wisdom in Ancient Greece is the owl. Specifically, the owl is associated with Athena, the goddess of wisdom, warfare, and crafts, who often had an owl depicted with her in ancient art and literature. The owl's keen eyesight and ability to hunt at night have contributed to its association with wisdom, as it symbolizes insight and knowledge. The phrase "wise as an owl" reflects this cultural perception. This ancient connection endures in modern times, often used to represent intelligence and learning in literature and popular culture.
