CALIBAN . . . When thou camest first, Thou strokedst me and madest 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 loved thee And show'd thee all the qualities o' the isle, The fresh springs, brine-pits, barren place and fertile: Cursed be I that did so! All the charms Of Sycorax, toads, beetles, bats, light on you! What can be inferred about the character of Caliban based on his description of "the fresh springs, brine-pits, barren place and fertile"?
