Read it through once

CALIBAN. I must eat my dinner. This island’s mine, by Sycorax my mother, Which thou tak’st from me. When thou cam’st first, Thou strok’st me and made much of me; wouldst give me Water with berries in ’t; and teach me how To name the bigger light, and how the less, That burn by day and night: and then I lov’d thee, And show’d thee all the qualities o’ th’ isle, The fresh springs, brine-pits, barren place, and fertile. Curs’d be I that did so! All the charms Of Sycorax, toads, beetles, bats, light on you! For I am all the subjects that you have, Which first was mine own King; and here you sty me In this hard rock, whiles you do keep from me The rest o’ th’ island.
