The Politics of Allegory and Example.
Incidental references ( esp. 238-43): for all of their radical satire, PPl and Pilgrim’s Progress are deceptive in the degree to which their allegories appear to convey socially and theologically descriptive sentiments. B passus 2 and 3 present an increasingly severe social criticism by progressively deserting allegory in favor of exemplative fiction, as WL’s complaints “exceed the capacity of allegory to contain them.”
Genre 24 (1991): 233-55.
