Viewpoint per chapter Both

Viewpoint and narration · lens E2 · compare across books

Counted: the narration is mostly play script (first person words per 1,000 outside speech: 58.8).

The play shifts between characters' perspectives, though Iago and Othello dominate the viewpoint in later chapters. Iago's soliloquies give the audience knowledge of his deception that Othello lacks, creating dramatic irony.
