Make a list of images that shakespeare uses to describe othello. what do the images suggest about othello?

Out of all the examples of Shakespeares animal imagery, it is perhaps that of "making the beast with two backs" that engenders the feelings of most disgust on a character, or indeed, an audience. The reference comes from Othello, where Iago tries to think of the very worst scenario he can possibly paint to a man considering his wife's fidelity, or otherwise.
