Daedalus was shut up in a tower to prevent his knowledge of the labyrinth from spreading to the public. He could not leave Crete by sea, as the king kept strict watch on all vessels. Since Minos controlled the land and sea routes, Daedalus set to work to fabricate wings for himself and his young son Icarus. When both were prepared for flight, Daedalus warned Icarus not to fly too high, because the heat of the sun would melt the wax, nor too low because the sea foam would make the wings wet and they would no longer fly. After a while the boy began to soar upward as if to reach heaven. The blazing sun softened the wax which held the feathers together and they came off. Icarus fell into the sea. His father cried, bitterly lamenting his own arts, and called the land near the place where Icarus fell into the ocean Icaria in memory of his child.
