text: explore the imagery of the devil and light and darkness in the play othello.? i need help with my as english coursework cause i'm really stuck!!! just general ideas of where to find quotes etc. and how i can link them all together!!! thanks for your help!! the most basic aspects of traditional western symbology – that white signifies purity and black signifies evil – are repeatedly challenged in othello. one example is in the character of bianca. her name in italian means "white", yet, as iago tells the audience, her name is again "but sign" of purity, as she is in fact "a housewife that by selling her desires buys herself bread and clothes" (act iv, scene i, ll. 95-96). ironically, just before desdemona pleads with othello that she is not a whore, bianca too protests to an accuser that she is "no strumpet, but of life as honest/ as you that thus abuse me" (act v, scene i, ll. 122-123)– leading the audience to realize that, just as with desdemona, the only evidence anyone has that bianca is a whore is iago's word, and cassio's (he calls her a "customer," whore {act iv, scene i, l. 120}).  heaven nevertheless remains a signifier of truth, and hell a signifier of misrepresentation in the play. the words thus recur frequently throughout othello, as othello struggles to join other signifiers to them: for example he says to an innocent desdemona that "heaven doth truly know that thou art false as hell". this shows strong contrasts between the two.  http://www.cummingsstudyguides.net/xothello.html#othello don't know whether it will help but it is a pretty good guide.
