The term 'Symbol of Wisdom' can be represented by two crossword solutions: OWL (3 letters) and ATHENA (6 letters). The OWL is a common symbol of wisdom and knowledge due to its association with the Greek goddess ATHENA. ATHENA was the goddess of wisdom, courage, inspiration, civilization, law and justice, mathematics, strength, war strategy, the arts, crafts, and skill. She was often depicted with an OWL perched on her shoulder, which was seen as a symbol of her wisdom.
