Science and Poetry: the two areas of life where contemporary practitioners are most dependent on the inventions and discoveries of their predecessors.
Carol Ann Duffy's The World's Wife contains some great poetry. It reminds me of two other poets. First, Robert Browning, as far as I know the inventor of the dramatic monologue in another persona for poetry. His influence on modern poetry is sweeping (and poetry with his influence is often sharper, harder, stronger than the confessional poetry that is everywhere in the 20th century). The other influence is Ted Hughes: in the modern verse, the ironic, somewhat detached tone, and the re-imagining of old myths.
