We first discussed the narrative structure of Canterbury Tales focusing on the narrator and the point of view shift that will occur as each pilgrim recites a tale.We then studied the prologue's harsh characterization of three clergy who are in the group of travelers. Joshua impressively pointed out the poet's criticism of church corruption and addressed the use of apparel as indirect characterization . We commented on Chaucer's use of details to convey religious hypocrisy . We further noted the use of sarcasm , and discussed the diction device ,euphemism.
