Comment on how the settings of Act 1, Scenes 1-3 help Shakespeare prepare the reader for tragedy? 

Shakespeare begins Othello in the metropolis that is Venice, Italy but soon quickly moves the setting to Cyprus- an island far from civilisation and authority thus causing isolation/alienation, a convention of tragedy.

Venice was a city of sophistication, a city of law and authority but also at the time Venice was known for its high competitive spirit regard trading , social status (patriarchal) and racial prejudice. As Othello was a “Moor” this instantly creates a feeling of isolation for the character, through out the beginning Act 1 Othello was either referred to through pronouns or derogatory terms such as “thick lips” and “black ram”, although those terms mainly came from Iago, in a negative sense. Furthermore the court room and feel of authority contrasts greatly with the lawless island of Cyprus.

Cyprus. The setting quickly changes to a sea port in Cyprus, a place which is supposed to be war ridden due to the invasion by the Turks, away from any form of authority that Venice possessed such as The Duke of Venice and his court all hell breaks loose. On Cyprus there is no support system for any of them especially for Desdemona who is later accused of adultery, she is vulnerable to the men and military way of life.
