In the begging Daedalus is the dad of Icarus and they need to escape from the tower. On lines 2-6 it states, " he flew into the range with its builder, Daedalus, and ordered him to shut up in the high that faced the lonely sea. In time, with the help of his young son Icurs. Daedalus manged to escape from the tower, only to find himself a prisoner on the island."
Adding on, on lines 16-19 its states "Daedalus then melted some wax made a skeleton in the shape of of birds wings. The one he had thread. This is the part where he had warned and was getting ready to go out and fly and then then the dad states " Keep at a moderate height don't fly to low or the fog will spray and clog your wings, if you fly to high the heat will melt the wax that holds them together."
Also, as Daedalus warned him about keeping a moderate height he went to high and the blazing sun was beating against the wax. On lines 70-73 its states that "The blazing sun beat down on the wings and so fend the wax . Small feathers fell from the wings and floated softly to the ground warning Icarus to stay his flight and glide to earth."
To continue, Daedalus went and followed to go pick up Icurs along with the feathers that dropped and took him to land. On lines 83-86 its states, " Daedulas hurried to save him, but it was too late. He gathered the boy in his arms and flew to land"
At the end, Daedalus barried him with his wings that he hung up his wings and said good bye . On lines 86-87 it states, "Weeping bitterly, he burried his small son and named land of Icaria in his memory"
One possible theme is stay in a safe zone don't go to high or don't go to low. On lines 45-47 its states that, “Keep at a moderate height, for if you fly too low, the fog and spray will clog your wings, and you fly to high the sun will heat the wax that holds them together.”
