Cadmus is the legendary founder and first king of Thebes in Greek mythology. A Phoenician prince turned Greek hero, he is credited with introducing the alphabet to Greece and with slaying a dragon sacred to Ares. His story blends heroic feats, divine trials, and tragic legacies, making him one of the most complex and culturally significant figures in early myth.
Family and Relations

Key Myths and Deeds
- Search for Europa: Cadmus was sent by his father to find his abducted sister Europa (taken by Zeus). Told not to return without her, he eventually gave up the search and sought divine guidance.
- Oracle of Delphi and Founding Thebes: Following the oracle’s advice, Cadmus followed a cow and founded a city where it lay down. This became Thebes.
- Slaying the Dragon: Cadmus killed a dragon sacred to Ares that guarded a spring. To atone, he served Ares for eight years. He then sowed the dragon’s teeth, which sprouted into armed warriors called the Spartoi. These warriors became the founders of Thebes’s noble families.
- Marriage to Harmonia: The gods gifted Cadmus and Harmonia a grand wedding, attended by Olympians. Their union produced children who would be central to later tragic myths, including Semele (mother of Dionysus) and Agave (mother of Pentheus).
- Transformation and Death: In old age, Cadmus and Harmonia were exiled from Thebes and eventually transformed into serpents by the gods, either as punishment or as a reward with symbolic meaning tied to rebirth and divine mystery.
Meaning and Etymology
The name “Cadmus” (Greek: Κάδμος) likely derives from Semitic roots, possibly connected to the Phoenician word for “east” or “origin.” This fits his narrative as a foreigner bringing civilization—both writing and city-building—to Greece. Cadmus symbolizes civilization, learning, and the fusion of foreign and native traditions. As a dragon-slayer and alphabet-bearer, he is both a warrior and a culture-bringer. His later suffering underscores the Greek view that great achievements often carry a divine price.
Representation in Art
Cadmus is often shown slaying the dragon or planting its teeth. Classical and Renaissance art also portrays his marriage to Harmonia, often with divine figures bearing gifts. In some artworks, he is shown with a scroll or stylus, alluding to his role in introducing writing to Greece.
