[Middle English laberinthe, from Latin labyrinthus, from Greek laburinthos; possibly akin to labrus, double-headed axe (used as a ritual weapon and a sign of authority in Minoan civilization, so that Greek laburinthos may originally have designated a Minoan palace as "the house of the double-headed axe"), of Lydian origin.]
