The phrase "as wise as Nestor" originates from Greek mythology, specifically from Homer's epic poems, the "Iliad" and the "Odyssey." Nestor was the King of Pylos and renowned for his wisdom and experience, often serving as a counselor to younger heroes. His character embodies the qualities of wisdom and age, making the comparison a way to highlight someone's sage advice or knowledge. The phrase has since entered common usage in English to denote great wisdom.
