Icarus was the son of the master craftsman Daedalus, the architect of the labyrinth of Crete. After Theseus, king of Athens and enemy of Minos, escaped from the labyrinth, King Minos suspected that Icarus and Daedalus had revealed the labyrinth's secrets and imprisoned them—either in a large tower overlooking the ocean or the labyrinth itself, depending upon the account. Icarus and Daedalus escaped using wings Daedalus constructed from feathers, threads from blankets, clothes, and beeswax. Daedalus warned Icarus first of complacency and then of hubris, instructing him to fly neither too low nor too high, lest the sea's dampness clog his wings or the sun's heat melt them. Icarus ignored Daedalus's instructions not to fly too close to the sun, causing the beeswax in his wings to melt. Icarus fell from the sky, plunged into the sea, and drowned. The myth gave rise to the idiom, "fly too close to the sun." In some versions of the tale, Daedalus and Icarus escape by ship.
