Document 9: Othello: Othello ("The Tragedy of Othello, the Moor of Venice)" is a tragedy by William Shakespeare, believed to have been written in 1603. It is based on the story "Un Capitano Moro" ("A Moorish Captain") by Cinthio, a disciple of Boccaccio, first published in 1565. The story revolves around its two central characters: Othello, a Moorish general in the Venetian army and his unfaithful ensign, Iago. Given its varied and enduring themes of racism, love, jealousy, betrayal, revenge and repentance, "Othello" is still often performed in professional and community theatre alike, and has been the source for numerous operatic, film, and literary adaptations.
Document 10: Stephano (The Tempest): Stephano ( ) is a boisterous and often drunk butler of King Alonso in William Shakespeare's play, "The Tempest".

Document 11: Tybalt: Tybalt is the main antagonist in William Shakespeare's play "Romeo and Juliet". He is the son of Lady Capulet's brother, Juliet's short-tempered first cousin, and Romeo's rival. Tybalt shares the same name as the character Tibert/Tybalt the "Prince of Cats" in "Reynard the Fox", a point of mockery in the play. Mercutio repeatedly calls Tybalt "Prince of Cats" (perhaps referring not only to Reynard but to the Italian word cazzo as well). Luigi da Porto adapted the story as "Giulietta e Romeo" and included it in his "Historia novellamente ritrovata di due Nobili Amanti" published in 1530. Da Porto drew on "Pyramus and Thisbe" and Giovanni Boccaccio's "Decameron". He gave it much of its modern form, including the lovers' names, the rival families of Montecchi and Capuleti, and the location in Verona. He also introduces characters corresponding to Shakespeare's Mercutio, Tybalt, and Paris. Da Porto presents his tale as historically true and claims it took place in the days of Bartolomeo II della Scala (a century earlier than Salernitano). Montague and Capulet were actual 13th-century political factions, but the only connection between them is a mention in Dante's" Purgatorio" as an example of civil dissension.
Document 12: Emilia (Othello): Emilia is a character in the tragedy "Othello" by William Shakespeare. The character's origin is traced to the 1565 tale, "Un capitano Moro" from Giovanni Battista Giraldi Cinthio's "Gli Hecatommithi". There, the character is described as young and virtuous, is referred to simply as the ensign's wife, and becomes Desdemona's companion in Cyprus. In Shakespeare, she is named Emilia, is the wife of Othello's ensign, Iago, and is an attendant to Othello's wife, Desdemona. While considered a minor character in the drama, she has been portrayed by several notable actresses on film, with Joyce Redman receiving an Academy Award nomination for her performance.
