Icarus was the son of Daedalus who flew too near the sun so that his wax wings melted and he plunged into the sea, named the Icarian after him. In much that he did, Icarus was similar to his father, and for this reason it seems appropriate to suggest a derivation such as eico, 'to yield', 'obey', 'follow' for his name. The noun eicon (English 'icon'), 'figure', 'likeness', would also produce this sense.
