What I love most about composing prologues and epilogues though is researching the characters from Chaucer's General Prologue and reinvigorating them, complete with all their traits, strengths and foibles.
By the way, for any Chaucer scholars reading this, writing Canterbury Tales is probably the best way to get into Chaucer's head. For although I started off by writing stories for specific Pilgrims and dovetailing them together, after the third tale I ceased writing epilouges and porlogues, and even occasionally changed which story was ascribed to which pilgrim on several. For instance, the story I originally envisaged as The Miller's Second Tale actually became The Knight's Second Tale.
Anyhow, enough of Chaucer. I have a St. George's Day zombie story to write. Don't ask!
