Once again events of this story follow the myth of Daedalus. According to the myth, Daedalus was such a skilled inventor and artisan that Minos decided he could not bear losing him to any other city. In particular, Minos could not risk the secrets of the labyrinth being revealed to anyone else. He locked Daedalus and Icarus up in a tower, and put strict controls on all land and sea routes out of the city. Daedalus and Icarus were therefore prisoners in Crete, and it was made perfectly clear that they would never be permitted to leave. It was for this reason that Daedalus invented the wings that they would eventually use to escape.
