In Greek mythology, Icarus flew too close to the sun while wearing wings made of feathers and wax created by his father Daedalus. As he soared higher and higher, the wax on his wings began to melt, causing him to fall into the sea and drown.
There is no specific indication in the myth about what Icarus was feeling as he flew through the air, but it can be assumed that he felt a sense of exhilaration and freedom as he soared through the sky. He may have also felt a sense of awe and wonder at the beauty of the world from a bird's-eye view. However, as the wax began to melt and he realized he was falling, he likely felt fear, panic and desperation.
