In order to escape, Daedalus devised a clever plan and sketched out his idea to his son. They would both fly away from the island like birds. It was risky, but both thought it wortha try. Using feathers attached together with wax and string, Daedalusmade them both a pair of wonderful wings. Harnessed to these they were able to take to the air, leaving those on the ground who witnessed theirflight amazed at their strange device. As they flew off over the sea their escape seemed certain. But Icarus, ignoring the warnings of his father, came too close to the sun. The wax holding his wings together melted and he plunged to his death in the ocean below.Translation1.
