Recurrence - Evocation - Connotation: Components for a Structuralist Analysis of Literary Texts

What are the theoretical and methodological resources of a linguist trained in structural methods, for the detection of those traits of text that are specifically literary traits? This question is approached from two angles: First from the angle of Eugenio Coseriu's version of text linguistics (focussing on recurrent returns of units on all levels), and second by using theories and methods developed by the US-philosopher of language and literary critic Kenneth Burke. Some illustrations from poetry and prose are provided.
