The term 'mythical flier' refers to four characters from Greek mythology: Icarus (6 letters), ROC (3 letters), Etana (5 letters), and DAEDALUS (8 letters). Icarus was the son of DAEDALUS, a master craftsman who created wings for himself and his son out of feathers and wax. Icarus flew too close to the sun, causing the wax to melt and him to fall into the sea. Etana was a Sumerian king who was said to have flown to heaven on the back of an eagle. The ROC was a giant bird from Arabian mythology that was said to be able to carry elephants in its talons.
