This is some monster of the isle with four legs, whohath got, as I take it, an ague. Where the devilshould he learn our language? I will give him somerelief, if it be but for that. if I can recover himand keep him tame and get to Naples with him, he's apresent for any emperor that ever trod on neat's leather.
This entire description of Caliban shows the colonolist type of view that effects the play. The native of this island is described as a literal monster, much in the same way that Europeans would described the peoples of the lands the colonized in the Americas and Africa. The comment about bringing him to an emporear as a gift even reflects actual history, as it was common to bring people from different lands to the leaders of imperial nations as gifts for slavery or to be put in a zoo. There types of treatments of Otherized people are reflected and go without judgement in this play, showing how it is very much a product of its time.
