under the rule of Oliver Cromwell. Poet John Donne, who was Dean of St Paul's Cathedral and a contemporary of Shakespeare, gave a sermon in 1624 perpetuating the Blood Libel – the entirely unsubstantiated antisemitic lie that Jews ritually murdered Christians to drink their blood and achieve salvation. In Venice and in some other places, Jews were required to wear a red hat at all times in public to make sure that they were easily identified, and had to live in a ghetto. Shakespeare's play may be seen as a continuation of this tradition. The title page of the Quarto indicates that the play was sometimes known as The Jew of Venice in its day, which suggests that it was seen as similar to Marlowe's early 1590s work The Jew of Malta. One interpretation of the play's structure is that Shakespeare meant to contrast the mercy of the main Christian characters with the Old Testament vengefulness of a Jew, who lacks the religious grace to comprehend mercy. Similarly, it is possible that Shakespeare meant Shylock's forced conversion to Christianity to be a "happy ending" for the character, as, to a Christian audience, it saves his soul and allows him to enter Heaven. Regardless of what Shakespeare's authorial intent may have been, the play has been made use of by antisemites throughout the play's history. The Nazis used the usurious Shylock for their propaganda. Shortly after Kristallnacht in 1938, The Merchant of Venice was broadcast for propagandistic ends over the German airwaves. Productions of the play followed in Lübeck (1938), Berlin (1940), and elsewhere within the Nazi territory. In a series of articles called Observer, first published in 1785, British playwright Richard Cumberland created a character named Abraham Abrahams, who is quoted as saying, "I verily believe the odious character of Shylock has brought little less persecution upon us, poor scattered sons of Abraham, than the Inquisition itself." Cumberland later wrote a successful play, The Jew (1794), in which his title character, Sheva, is portrayed sympathetically, as both a kindhearted and generous man. This was the first known attempt by a dramatist to reverse the negative stereotype that Shylock personified. The depiction of Jews in literature throughout the centuries bears the close imprint of Shylock. With slight variations much of English literature up until the 20th century depicts the Jew as "a monied, cruel, lecherous, avaricious outsider tolerated only because of
