King Minos imprisoned Daedalus in the labyrinth for several intertwined reasons. Primarily, Daedalus was the skilled inventor who designed the labyrinth to imprison the Minotaur, a monstrous creature born from Minos's wife Pasiphae and a sacred bull. Minos wanted to keep the secret of the labyrinth's design and the Minotaur's existence hidden, fearing Daedalus might reveal the route through the labyrinth or expose the origins of the Minotaur. Additionally, Minos was angry at Daedalus for aiding the escape of Theseus, who killed the Minotaur, and possibly for helping Pasiphae in her unnatural mating with the bull using a wooden cow contraption crafted by Daedalus. To prevent any further betrayal or revealing the labyrinth's secrets, Minos imprisoned Daedalus and his son Icarus either in the labyrinth itself or in a high tower overseen by the sea, from which Daedalus famously escaped using wings he made for himself and Icarus.
