The hero who fought the Minotaur in the Labyrinth is Theseus. According to Greek mythology, he volunteered to enter the labyrinth, a maze designed by Daedalus to hold the Minotaur—a creature with the body of a man and the head of a bull. With the help of Ariadne, Theseus used a thread to navigate the labyrinth, ultimately slaying the Minotaur and escaping. This myth symbolizes bravery, ingenuity, and the struggle against chaos, reinforcing Theseus's status as a cultural hero in Athenian lore and reflecting broader themes of triumph over adversity.
