In a world where most people could not read, symbols were how the Greeks identified their gods in art, temples, and daily life. A figure holding a thunderbolt was immediately recognizable as Zeus. An owl on a coin meant the coin was from Athens, city of Athena. A trident carved above a doorway meant the building was under Poseidon's protection. These symbols functioned as a visual language that communicated religious identity across the entire Mediterranean world, regardless of literacy or dialect. Many of these symbols persist today: the caduceus in medicine, the owl in education, the trident in naval insignia.
