Browse nicknames →The Story of Theseus
Theseus (Θησεύς) comes from the Greek verb 'tithemi' meaning 'to set' or 'to place,' suggesting one who sets things right or establishes order. In Greek mythology, Theseus was the legendary founder-king of Athens, son of either the mortal Aegeus or the god Poseidon. He is best known for slaying the Minotaur in the Labyrinth of Crete with the help of Ariadne.
Theseus remains extremely rare as a given name, primarily used by classically-minded parents who love Greek mythology. The rise of mythological names like Orion, Perseus, and Atlas has created a renewed interest in ancient Greek heroes as name sources.
Theseus was the national hero of Athens, the city that gave birth to democracy, philosophy, and drama. The 'Ship of Theseus' is one of philosophy's most famous thought experiments about identity and change. His name is embedded in Western intellectual culture.
