Tropics and Metaphor Analysis
Tropes can be analyzed to create a "map" of a discourse and reveal aspects of the discourse that might not be obvious in a casual reading. Until recently, most "methods" were limited to metaphor analysis; or simple collapsed all tropes into the term "metaphor", effectively replacing "trope" as a category. This page points to several traditions of metaphor and tropic analysis that have been used in the field, and includes links to web resources, textbooks, and bibliographies.
