This thesis examines how Gwyn Thomas and Ron Berry interact with and respond to landscape and environment in their fictional and non-fictional writing. Exploring how the writers negotiate the convergence of the industrial and the rural/natural in the uplands of the south Wales coalfield, in particular the Rhondda Fawr Valley, the study considers the literary geographies their work creates. Examining the themes of the cultural and political use of landscape and rural imagery, the manifestation of authority in landscapes, the impact of industrialisation and de-industrialisation, the uncanny underground environment and its dynamic interactions with the ground above, and post-industrial environmental issues, the study re-positions two industrial writers of Wales to reveal the significance of landscape, place and environment in their writing.
