He forgot to change the color of his sails from black to white, which would have informed his father of his success. Instead, Aegeus upon seeing the black sails, cast himself into the sea. That sea (the Aegean) still bears his name to this day.
Actually Theseus killed the Minotaur with his bare hands. The princess of Crete gave him the magic thread to find his way out of the Labyrinth.
He thought Theseus was dead because on the way back from Crete, the sailors forgot to change the sails from black to white, which would signal that Theseus was alive...dumb bastards.
Ariadne gave THeseus a harpin that turned into a sword named Anuklusmos, or Riptide in English,to defeat Ladon, the dragon, that gaurds the tree of golden apples of immortality.In return,Theseus promised Ariadne to marry her.When they sailed off together for home they stopped to rest on Calypso's island.Here THeseus sailed off the island without Ariadne while she was sleeping.For those of you who don't read Percy Jackson, Ariadne provided Theseus with a ball of twine (given to her by Daedalus), with which he could navigate the Labyrinth.Ariadne was the daughter of King Minos of Crete. When Theseus was brought to Crete as one of the sacrifices for the Minotaur, Ariadne gave him a spool of string so that once he killed the Minotaur he could find his way out of the Labyrinth. In return for her aid, Theseus took Ariadne with him when he left Crete; however, he later abandoned her on a deserted island.
King Minos's daughter, Princess Ariadne of Crete.
Theseus is a myth character. He was from Athens and his people where being sent to Crete as food for the kings son the Minotaur (a person with the head of a bull), as the king of Athens and the king of Crete had a fight. Since the king of Crete won he demanded that. Theseus wanted to stop it so he was sent to Crete as a slave. He had to go through a labyrinth first (whoever went in never came out). So the kings daughter helped him succeed. She gave him a very long peace of rope so that he could tie one end on a tree trunk and the other on himself so that he could find his way out after defeating the Minotaur. He killed the Minotaur and no more people were sent there again.
In Greek mythology, Ariadne was the daughter of King Minos of Crete. She helped Theseus navigate the Labyrinth and defeat the Minotaur by giving him a ball of string to help him find his way out. Theseus later abandoned Ariadne on the island of Naxos, where she was later found and married by the god Dionysus.
Ariadne helped the hero Theseus escape from the labyrinth by giving him a spool of string so he could retrace his steps. Theseus took her with him when he fled Crete, but he later left her marooned on an island on his way back to Athens.
He was not necessarily tricked, but more or less forced. Procrustes invited Theseus into his home where he was fed. A servant told Theseus not to sleep in the bed. Theseus forced Procrustes to test his bed and he was killed.
No, he did not. Theseus married Phaedra, the sister of Ariadne. Ariadne married Dionysus. Theseus had a few wives/lovers, including supposedly Helen (of Troy, daughter of Zeus) with whom he had Iphigeneia. Then with Peridone he had Melanippus. With Hippolyte (Queen of the Amazons) he had Hippolytus, he also had a wife Iope or Aegee.
He was forgetful. He forgot ot change the white sails to black on his way home to Athens.
theseus is not a god Theseus is a hero and he the the man who killed the minotaur and found his way out of the labyrinth with daedalus's help
Theseus was a king of Athens famous for many exploits, and appearing in works by many authors and on countless vases. There is some confusion about Theseus' parentage, some say he is the son of Aegeus and Aethra, and others the son of Poseidon and Aethra. Apollodoros and Hyginus say Aethra waded out to Sphairia after sleeping with Aegeus, and lay there with Poseidon. The next day, Aegeus, who had been visiting Aethra at Troizen, left for his home city of Athens. As he left, he left sandals and a sword under a large rock; should Aethra bear a male child, she was to send him to Athens to claim his birthright as soon as he was old enough to lift the rock and retrieve the items. Aethra gave birth to Theseus, who came of age and set off for Athens with the sword and sandals, encountering and defeating six murderous adversaries along the way. When Theseus reached Athens, Medea, the wife of Aegeus, persuaded Aegeus to kill the as of yet unrecognized Theseus by having him attempt to capture the savage Marathonian Bull. Theseus does the unexpected and succeeds, so Medea tells Aegeus to give him poisoned wine. Aegeus recognizes Theseus' sword as he is about to drink and knocks the goblet from his lips at the last second. According to Plutarch and Philochoros, on the way to Marathon to kill the bull, Theseus encounters a fierce storm and seeks shelter in the hut of an old woman named Hecale. She promises to make a sacrifice to Zeus if Theseus comes back successful. He comes back, finds her dead, and builds a deme in her name. Some time after Theseus return to Athens, trouble stirs and blood flows between the houses of Aegeus in Athens and Minos, his brother in Crete. War and drought ensues and an oracle demands that recompense be made to Minos. Minos demands that seven maidens and seven youths are to be sacrificed to the Minotaur every nine years. Theseus is among the chosen victims and sails off to Crete, promising to Aegeus that his ship's black flag would be replaced with a white flag if Theseus is victorious. In Crete, Minos molests one of the maidens and Theseus becomes angry and challenges him, boasting of his parentage by Poseidon. Minos, son of Zeus is amused and asks Theseus to prove his heritage by retrieving a ring from the depths of the ocean. Theseus being a son of Poseidon succeeds. Ariadne, a young woman in Crete already betrothed to Dionysus, falls in love with Theseus and helps him defeat the Minotaur. Ariadne then leaves Crete with Theseus, who abandons her on Dia (at Athena's behest, according to Pherekydes). In returning to Athens Theseus forgets to switch the black sail with the white one. Aegeus, consequently, watching from afar believes his son is dead and hurls himself into the sea, named the 'Aegean' after him. After Aegeus' death, Theseus must contend against Pallas for the throne. Theseus gets wind of a planned assassination against him and spoils the ambush, killing Pallas and gaining the throne. Theseus and a good friend of his by the name of Pirithous wanted to marry daughters of Zeus, and begin their quest by abducting Helen. Theseus wins a bet and gets Helen, but must accompany Pirithous to Hades to recover Persephone for him. There is much disagreement here about what happens in Hades, but many traditions say only Theseus makes it back out. Theseus does two noteworthy patriotic acts to Thebes, accepting Oedipus at Kolonus, and helping Adrastus bury the Seven, fallen in the struggle for the throne of Thebes. Late in his life Theseus loses popularity in Athens and is exiled. He wanders to Scyrus where he is hurled off a cliff by Lycodemes.
