Daedalus invented wings made of feathers and wax to help himself and his son Icarus escape from the Labyrinth. He crafted the wings by attaching feathers with candle wax to pieces of wood that acted as the frame. This invention allowed them to fly away from Crete, where they were trapped. Daedalus warned Icarus not to fly too close to the sun, as the heat would melt the wax, nor too close to the sea, as the moisture could dampen the wings. However, Icarus ignored these warnings and flew too high, causing his wings to melt and leading to his fall and drowning in the sea. This story illustrates Daedalus' ingenuity in creating a means of escape from the Labyrinth through flight. In summary, Daedalus' key invention to escape was the wings made of feathers and wax.
