The Prince of Morocco explains his thoughts on each of the caskets as he reads the inscriptions on them. He says the lead casket is not worth hazarding everything for and quickly dismisses it. When he comes to the silver casket he comments, ‘Thou dost deserve enough and yet enough/May not extend so far as to the lady:’ (Act II Scene vii).
He exposes his secret fear that he does not deserve Portia. He considers silver not to be grand enough for Portia and dismisses this casket also. He settles upon the gold casket thinking that ‘what many men desire’ describes Portia. His choice can be explained by the fact that it is only his royal blood and his fortune that lends him respect from the people of Venice. This means Morocco judges on outward appearances. The quotation, ‘All that glisters is not gold’ befits his character which is insecure and shallow.
