This is some monster of the isle with four legs, who hath got, as I take it, an ague. Where the devil should he learn our language? I will give him some relief, if it be but for that. If I can recover him and keep him tame and get to Naples with him, he’s a present for any emperor that ever trod on neat’s leather.

– William Shakespeare

The Tempest, Act 2, Scene 2. Stephano calls Caliban a monster when he sees him, because of his deformed shape, having been born to a witch. He plans to take him to Naples and make him a present for some king.
