How does Shakespeare present the world of Venice in the first act?

Venice is shown to be a bastion of civilization just boardering the "heathen" hoardes of Turks and military unrest. Venice is shown to be an orderly and reletivly quiet place. At one point Barbantio is asked if he has been robbed and he answers,

"What tellâst thou me of robbing? This is Venice; My house is not a grange."

This Venice is a place in stark contrast wth the intense visceral Othello who the people credit with Venice's military success. It is important to note that the farther one gets away from England the more prone to chaos a place gets. No playwright would dare to offend the Queen by suggesting anything less than perfection in England.
