Ariadne was the daughter of King Minos of Crete. Minos had Daedalus build a Labyrinth, a house of winding passages, to house the bull-man, the Minotaur, the beast that his wife Pasiphae bore after having intercourse with a bull. (Minos had refused to sacrifice a bull to Poseidon, as the king promised, so the god took revenge by causing his wife to desire the bull--but that's another story.) Minos required tribute from Athens in the form of young men and women to be sacrificed to the Minotaur.
Theseus, an Athenian, volunteered to accompany one of these groups of victims to deliver his country from the tribute to Minos. Ariadne fell in love with Theseus and gave him a thread which he let unwind through the Labyrinth so that he was able to kill the Minotaur and find his way back out again.
que hasta aquí me ha llevado"-
Y del cielo cae el hilo arreglado,
tiene un nudo,
esta empalmado,
pero para encontrar la salida
es lo suficientemente largo.
Ariadna lo ha salvado.
