"Theseus (UK: /ˈθiːsjuːs/, US: /ˈθiːsiəs/; Greek: Θησεύς [tʰɛːsěu̯s]) was the mythical king and founder-hero of Athens. Like Perseus, Cadmus, or Heracles, Theseus battled and overcame foes that were identified with an archaic religious and social order. His role in history has been called "a major cultural transition, like the making of the new Olympia by Hercules".
Theseus was a founding hero for the Athenians in the same way that Heracles was the founding hero for the Dorians. The Athenians regarded Theseus as a great reformer; his name comes from the same root as θεσμός (thesmos), Greek for "rule" or "precept". The myths surrounding Theseus—his journeys, exploits, and friends—have provided material for fiction throughout the ages." - (en.wikipedia.org 01.01.2020)
