'So will I turn her virtue into pitch And out of her own goodness make the net
That shall enmesh them all'

As an incarnation of evil and a catalyst of jealousy, vengeance and murder, lago is the mainspring of Othello.

One of Shakespeare's most intriguing characters, lago sets out to convince Othello of his wife's infidelity with Cassio. His motives are diverse - revenge, vanity, envy - but he succeeds in arousing strong suspicions in Othello's breast. Though noble and courageous, Othello finally allows himself to be duped by the coldly
calculating lago, and 'Chaos is come again'.
