it's shakespear's one of the greatest dramatic creations
his function in the play is supposed to be the obstacle,the man who stands on the way of love stories,such a kind of man is a traditional figure in romantic stories
the way that he is a jew,is,in a sense,accidental.
shakespeare wanted to contrast liberality against selfishness in terms of money and in terms of love,
he is a kinda jewish merchant who is bent on revenge,he threatens to take a pound of flesh from another merchant if his debt is not paid in time
he mainly exemplifies many of the negative traits
