First, let's examine what news Iago and Roderigo brought to Brabanzio in Act One of Othello, by William Shakespeare. Roderigo, who is in love with Brabanzio's daughter, Desdemona, is enraged to hear that Desdemona has just married Othello. Both men hate Othello, and so they decided to misinform Brabanzio of what Desdemona has done. They go to him and tell him that she and Othello are having sex (or "making the beast with two backs", as Iago so eloquently puts it). Brabanzio is enraged and angered beyond belief. He sets out at once in search of his daughter. When he does not find her, he beings to believe that Othello has somehow managed to trick Desdemona and has her under some sort of spell.
