Cassius: messala, this is my birthday . . now i change my mind, and partly credit things that do presage. . two mighty eagles fell . . and in their steads do ravens, crows, and kites fly o’er our heads and downward look on us, as we are sickly prey. their shadows seem a canopy most fatal under which our army lies, ready to give up the ghost. how does cassius’ use of figurative language in the bolded lines foreshadow the possible fate of his and brutus’ army?

By using figurative language, Shakespeare creates a visual image of Octavius’ army overtaking them like inescapable death. Cassius’ words foreshadow later events in act 5.
