in Cyprus after defeating Turkish ships and throughout the play various characters proclaim how noble he is: "Othello ... our noble and valiant general" pg. 81, said by a herald and "[Othello] ... the noble Moor, whom our full senate/ Call all in all sufficient," pg 191, said by Lodovico. Also, Othello is called noble by Iago in his soliloquy: "[Othello] is of a constant, loving noble nature, And I dare think he'll prove to Desdemona/ A most dear husband", on pg 79. Thus, Shakespeare does an excellent job making Othello be a successful person and a noble character, however following Aristotle's standards Shakespeare makes his tragic hero lose superiority and success by the end of the play.
             Along with this tragic hero, since he is a human being, he must display an error in judgment or flaw in character, which is Aristotle's second characteristic. This is usually referred to as a harmartia. Shakespeare also uses this idea of Aristotle's tragic hero with his character Othello. Othello, while being noble and successful, is very gullible during the play. Although he does not want to believe everything Iago has told him about Desdemona, which are lies, he does and finally admits in Act III, "Now do I see 'tis true." Besides this, Iago even knows that Othello is tricked very easily and proclaims this to us at the end of Act I: "And will as tenderly be led by 'th nose/ As asses are."
