The Merchant (play) would make a big profit, but this did not happen. He wrote a book about the play in 1999, "The Birth of Shylock and the Death of Zero Mostel". In this play, Shylock is a good man and Antonio's, the title character in Shakespeare's play, good friend. They bond in their love of knowledge and mutual dislike of the antisemitism in their community. Shylock's demand for a pound of flesh is meant as a jest, but he can not retract it. Both Shylock and Antonio are relieved when the demand is denied in court. Reviewing "The Merchant", critic Michael Billington
The Merchant of Venice edition in 1600 states that it had been performed "divers times" by that date. Salerino's reference to his ship the "Andrew" (I,i,27) is thought to be an allusion to the Spanish ship "St. Andrew," captured by the English at Cádiz in 1596. A date of 1596–97 is considered consistent with the play's style. The play was entered in the Register of the Stationers Company, the method at that time of obtaining copyright for a new play, by James Roberts on 22 July 1598 under the title "The Merchant of Venice", otherwise called "The Jew of Venice". On 28 October 1600
