“Her father left a will stipulating each of her suitors must choose correctly from one of three caskets – one each of gold, silver and lead. If he picks the right casket, he gets Portia. The first suitor, the Prince of Morocco, chooses the gold casket, interpreting its slogan, "Who chooseth me shall gain what many men desire," as referring to Portia. The second suitor, the conceited Prince of Arragon, chooses the silver casket, which proclaims, "Who chooseth me shall get as much as he deserves", as he believes he is full of merit. Both suitors leave empty-handed, having rejected the lead casket because of the baseness of its material and the uninviting nature of its slogan, "Who chooseth me must give and hazard all he hath." The last suitor is Bassanio, whom Portia wishes to succeed, having met him before. Bassanio chooses the lead casket and wins Portia's hand.” (From Wikipedia: http://en.wikipedia.org/wiki/The_Merchant_of_Venice}
Bassiano replies that she has left him speechless—so full of love and joy, and that if the ring were to ever leave his finger than may his life depart as well.
