When Theseus was sent by his father to convey the tribute of the Athenians to Minotaurus, Ariadne fell in love with him, and gave him the string by means of which he found his way out of the Labyrinth, and which she herself had received from Hephaestus. Theseus in return promised to marry her, and she accordingly left Crete with him but when they arrived in the island of Dia (Naxos), she was killed there by Artemis.
The words added in the Odyssey are difficult to understand, unless we interpret them with Pherecydes by "on the denunciation of Dionysus," because he was indignant at the profanation of his grotto by the love of Theseus and Ariadne. In this case Ariadne was probably killed by Artemis at the moment she gave birth to her twin children, for she is said to have had two sons by Theseus, Oenopion and Staphylus.
The more common tradition, however, was, that Theseus left Ariadne in Naxos alive but here the statements again differ, for some relate that he was forced by Dionysus to leave her and that in his grief he forgot to take down the black sail, which occasioned the death of his father.
According to this tradition, Ariadne put an end to her own life in despair, or was saved by Dionysus, who in amazement at her beauty made her his wife, raised her among the immortals, and placed the crown which he gave her at his marriage with her, among the stars. (Theogony of Hesiod 949. Metamorphoses by Ovid I )
There are several circumstances in the story of Ariadne which
offered the happiest subjects for works of art, and some of the
finest ancient works, on gems as well as paintings, are still
extant, of which Ariadne is the subject.
