Minos searched for Daedalus by travelling from city to city asking a riddle. He presented a spiral seashell and asked for it to be strung all the way through. When he reached Camicus, King Cocalus, knowing Daedalus would be able to solve the riddle, fetched the old man. He tied the string to an ant, which walked through the seashell, stringing it all the way through. Minos then knew Daedalus was in the court of King Cocalus and demanded he be handed over. Cocalus managed to convince him to take a bath first. Cocalus' daughters then killed Minos.
