The Merchant of Venice

Bassanio, a young Venetian of noble rank, wishes to woo the beautiful and wealthy heiress Portia of Belmont. Having squandered his estate, Bassanio approaches his friend Antonio, a wealthy merchant of Venice who has previously and repeatedly bailed him out, for 3,000 ducats needed to subsidise his expenditures as a suitor. Antonio agrees, but since he is cash-poor - his ships and merchandise are busy at sea - he promises to cover a bond if Bassanio can find a lender, so Bassanio turns to the Jewish moneylender Shylock and names Antonio as the loan's guarantor.
