The original clue, a ball of yarn, was given to Theseus by Ariadne, the daughter of Minos, to help him find his way back out of the Labyrinth after he had killed the youth-eating Minotaur
"clue (n.) 1590s, spelling variant of clew "a ball of thread or yarn," in this sense with reference to the one Theseus used as a guide out of the Labyrinth. The purely figurative sense of "that which points the way" is from 1620s. As something which a bewildered person does not have, by 1948." ‎- Eivind
This is perhaps also the original labyrinth: "labyrinth (n.) c. 1400, laberynthe (late 14c. in Latinate form laborintus) "labyrinth, maze," figuratively "bewildering arguments," from Latin labyrinthus, from Greek labyrinthos "maze, large building with intricate passages," especially the structure built by Daedelus to hold the Minotaur near Knossos in Crete, from a pre-Greek language; perhaps related to Lydian labrys "double-edged axe," symbol of royal power, which fits with the theory that the labyrinth was originally the royal Minoan palace on Crete and meant "palace of the double-axe." Used in English for "maze" early 15c., and in figurative sense of "confusing state of affairs" (1540s)." ‎- Eivind
