Discribe in detail of mosque of iris and ceres in the play

Ferdinand swears to Prospero that they shall wait until the ceremony to consummate their marriage, and then Prospero calls upon Ariel to perform one of his last acts of magic. A betrothal masque is performed for the party by some of Prospero's magical spirits; Juno, Ceres, and Iris are the goddesses who are represented within the masque, and the play speaks about the bounties of a good marriage, and blesses the happy couple. This act of magic so captivates Prospero that he forgets Caliban's plot to kill him; for a moment, he almost loses control, but manages to pull himself out of his reverie and take action.
