Enter PROSPERO above, invisible. Enter several strange Shapes,
bringing in a banquet; they dance about it with gentle actions of
salutation; and, inviting the King, &c. to eat, they depart
ALONSO: Give us kind keepers, heavens! What were these? 
SEBASTIAN: A living drollery. Now I will believe
That there are unicorns, that in Arabia
There is one tree, the ph¦nix' throne, one ph¦nix
At this hour reigning there.
