Greek mythology served as a critical framework shaping the beliefs, customs, and artistic expressions of ancient cultures, particularly in Greece and Rome. It provided insights into human nature, morality, and the cosmos through stories of gods, heroes, and mythical creatures. These myths explained natural phenomena, influenced daily life, and offered lessons on virtues and vices. They were deeply intertwined with religious practices and community values, contributing to the foundation of Western literature, philosophy, and art. As a cultural touchstone, Greek mythology allowed for the exploration of complex themes such as love, power, and mortality, resonating through time into modern storytelling.
