A Greek Hero

Theseus was a hero of Greek mythology associated with the city-state of Athens, and best known for slaying the Minotaur. Theseus was also the leader who unified the Greek region of Attica under a single ruler, which paved the way for the development of democratic principles in Athens.

Theseus' father was Aegeus, king of Athens, and his mother was Aethra, daughter of the king of Troezen. King Aegeus had no children and no heir, and so he traveled to the Delphic Oracle to seek counsel. On the journey home, he stopped to visit King Pittheus of Troezen and became drunk. Pittheus offered his daughter to Aegeus, and she became pregnant.

Aegeus resumed his journey, but left Aethra with her father in Troezen. He instructed her to send their child, if it was a boy, to Athens when he reached a certain age. As the story goes, Aegeus left a sword and sandals under a very heavy rock. If their son was able to retrieve the sword and sandals, he would be recognized as Aegeus' heir upon arrival in Athens.

When Theseus reached the age of a young man, his mother shared Aegeus' instructions with the boy. Theseus successfully moved the boulder and claimed the sword and sandals of Aegeus. He then set out for Athens, encountering outlaws and monsters along the way. By defeating these obstacles and many more over the course of his life, Theseus became a Greek hero.

Pityocamptes & Sciron

On the way to Athens but near Corinth, Theseus fought and killed Pityocamptes, whose name means 'pine bender.' Pityocamptes tied his victims to two different pine trees bent to the ground and then released the trees, tearing the victims to pieces. Theseus also killed Sciron, an outlaw who pushed unsuspecting travelers off a cliff to be eaten by a giant turtle, by giving him a taste of his own medicine.

The Marathon Bull & Queen Medea

After arriving in Athens, Theseus sought out the king. However, he was quickly recognized by Queen Medea, who wanted her own son to be the heir to the throne and convinced the king to send Theseus on a heroic mission. Aegeus asked Theseus to capture the Marathon bull, a bull captured initially by Heracles and brought to Attica. Theseus succeeded in his mission, putting a stop to the bull's terrorizing of the countryside around Marathon.

However, Medea manipulated Aegeus into thinking Theseus was a threat, and they plotted to kill him by poison. Aegeus held a banquet in honor of Theseus' victory over the Marathon bull, and during the banquet, Medea dropped the poison in Theseus' drink. Just as Theseus was about to drink the poison, Aegeus recognized the sword and sandals and realized Theseus was his rightful heir. Aegeus knocked the poisoned cup out of Theseus' hands and proclaimed him his heir. Medea and her children were then banished from Athens.

The Labyrinth & the Minotaur

Athens was a tribute state to Crete under the leadership of King Minos, who demanded a tribute of seven boys and seven girls each year to feed his Minotaur. The Minotaur was a monster with the body of a man and the head of a bull housed within a great labyrinth. Theseus volunteered to be one of the tributes and King Aegeus reluctantly agreed. However, he asked that on the return home, if Theseus was successful, that he fly white sails, but if not, to fly black sails.

Upon arriving in Crete, Ariadne, the daughter of King Minos, fell in love with Theseus and agreed to help him kill the Minotaur if he agreed to take her with him when he left. She then gave him a length of string which he tied to the doors of the labyrinth and let out behind him as he searched for the Minotaur, which he found in the center of the labyrinth. Theseus then fought and killed the beast!

Afterwards, he traced his path back to the doors of the labyrinth using the string. Theseus then set sail with Ariadne and all of the tributes. However, Theseus was not in love with Ariadne: on a stopover in Naxos, she fell asleep on the beach, and he left her there.

Returning to Athens, Theseus failed to change the sails per Aegeus' instructions and sailed into port flying a black sail. Stricken with grief over the perceived loss of Theseus, Aegeus threw himself off a cliff. With the death of Aegeus, Theseus became king of Athens and set to uniting the smaller villages in the countryside surrounding the city.
