Bring out the importance of the Epilogue in The Jew of Malta

Despite all the havoc he has wreaked, Barabas serves a crucial role in the safety of Malta all the way to his death. His money buys Malta a month's time, during which Martin del Bosco minimizes damage to the city by helping the Turks to an easy victory; finally, he liberates Ferneze and allows Malta to assert its independence once and for all. Yet, it is not at all clear that the ending should be considered "happy." The governor Ferneze has after all revealed himself to be a hypocrite and traitor, no less Machiavellian than Barabas-in contrast to the invading Turks, who have acted with relative courtesy. T. S. Eliot famously called The Jew of Malta a "tragic farce." It is perhaps a farce because the tragic elements remain conspicuously unnoticed by the surviving characters, and a tragedy because the farcical elements ultimately lead to death.
