The contest for Portia’s hand, in which suitors from various countries choose among a gold, a silver, and a lead casket, resembles the cultural and legal system of Venice in some respects. Like the Venice of the play, the casket contest presents the same opportunities and the same rules to men of various nations, ethnicities, and religions. Also like Venice, the hidden bias of the casket test is fundamentally Christian. To win Portia, Bassanio must ignore the gold casket, which bears the inscription, “Who chooseth me shall gain what many men desire” (II.vii.5), and the silver casket, which says, “Who chooseth me shall get as much as he deserves” (II.vii.7). The correct casket is lead and warns that the person who chooses it must give and risk everything he has. The contest combines a number of Christian teachings, such as the idea that desire is an unreliable guide and should be resisted, and the idea that human beings do not deserve God’s grace but receive it in spite of themselves. Christianity teaches that appearances are often deceiving, and that people should not trust the evidence provided by the senses—hence the humble appearance of the lead casket. Faith and charity are the central values of Christianity, and these values are evoked by the lead casket’s injunction to give all and risk all, as one does in making a leap of faith. Portia’s father has presented marriage as one in which the proper suitor risks and gives everything for the spouse, in the hope of a divine recompense he can never truly deserve. The contest certainly suits Bassanio, who knows he does not deserve his good fortune but is willing to risk everything on a gamble.
The pound of flesh that Shylock seeks lends itself to multiple interpretations: it emerges most as a metaphor for two of the play’s closest relationships, but also calls attention to Shylock’s inflexible adherence to the law. The fact that Bassanio’s debt is to be paid with Antonio’s flesh is significant, showing how their friendship is so binding it has made them almost one. Shylock’s determination is strengthened by Jessica’s departure, as if he were seeking recompense for the loss of his own flesh and blood by collecting it from his enemy. Lastly, the pound of flesh is a constant reminder of the rigidity of Shylock’s world, where numerical calculations are used to evaluate even the most serious of situations. Shylock never explicitly demands that Antonio die, but asks instead, in his numerical mind, for a pound in exchange for his three thousand ducats. Where the other characters measure their emotions with long metaphors and words, Shylock measures everything in far more prosaic and numerical quantities.
The ring given to Shylock in his bachelor days by a woman named Leah, who is most likely Shylock’s wife and Jessica’s mother, gets only a brief mention in the play, but is still an object of great importance. When told that Jessica has stolen it and traded it for a monkey, Shylock very poignantly laments its loss: “I would not have given it for a wilderness of monkeys” (III.i.101–102). The lost ring allows us to see Shylock in an uncharacteristically vulnerable position and to view him as a human being capable of feeling something more than anger. Although Shylock and Tubal discuss the ring for no more than five lines, the ring stands as an important symbol of Shylock’s humanity, his ability to love, and his ability to grieve.
