The Tragedy of Othello, the Moor of Venice is based on the Italian short story Un Capitano Moro (A Moorish Captain) by Cinthio, a disciple of Boccaccio, first published in 1565. The work revolves around four central characters: Othello, a Moorish general in the Venetian army; his new wife, Desdemona; his lieutenant, Cassio; and his trusted ensign, Iago.
