Any student of Cervantes' literary production must at some point take into account the theories that inspired the plan and creation of Los Trabajos de Persiles y Sigismunda for, of all Cervantes' works, it is the one most directly related to the author's awareness of literary theory. This volume, in attempting to clarify the Persiles, traces the major influences reflected in the Renaissance literary theories which inspired it, examines Cervantes' ambivalent attitude toward those theories as revealed in his works, and provides a close examination of the structure of the Persiles.
