The novel Possession contains some spot-on mimicry of several different writing styles, including lengthy poems by two fictional Victorian poets. The character of RH Ash in particular feels as if there is some model, or models, for him. He has a very distinct style and a distinct set of interests (including naturalism and Greek and Norse myths).
Is he similar to Tennyson, or Browning, or some other real poet, or an amalgam? Or is he purely Byatt's creation?
