But first . . .

Soon after I began working on Chaucer's reference to the moon's exaltation, which appears to be an astrological "mistake," I realized how much background would be necessary to be able to accept my explanation. So, first I'll give you what I see as the basic structure of the plan for the Canterbury Tales.
     Here is the most important thing to keep in mind: The movement of the zodiac is the basis of the plan. That fact is not obvious on the surface because allegories were intended to be obscure. Searching for the inner meaning, in this most popular literary form in Chaucer's day, challenged and entertained. Discovering the covert message was looked upon as a reward.
     The General Prologue introduces the characters. We've dealt with that already in the entries called "Written in the Stars." That's where Chaucer delights in teasing as he says the Friar has eyes (2 major stars in the constellation) that twinkle in his head like stars on a frosty night; and the Cook "makes " blankmanger--white manger--because a star cluster in this zodiac sign is called The Manger.
     Movement begins after the introductions are complete. The poet uses ambiguous words--degree and array--to describe the Pilgrims. Both words can indicate a quality of human or celestial appearance. When the Host gathers the Pilgrims together, that is when they set out on their journey. Now, to talk about the succession of signs of the zodiac is the same as talking about Time. Time, in the Middle Ages, was pictured as a circle. When all of the stars returned to the place where they were when Time began, the circle would close. That would be the end of Time, the end of the world, the Day of Judgment. As Chaucer says:

. . . in certain years space
Every star should come into its place
Where it was first, and all should have in mind
That in this world done is all mankind.

Those lines express Chaucer's complete design. Before the journeyers (the celestial travelers) set out, the Host tells them they will all return to their point of departure at the end of their journey. At the conclusion, the position of all twenty-nine will be--Here in this place, sitting by this post, When we come again.   
     His whole intention is subtly disclosed. Time begins as they leave and is about to end as the Host calls on the last storyteller. He urges the Pilgrim to make haste; the day is at an end.
      Let's repeat--the movement of the zodiac is the basis of the plan. The disguised travelers are not earthbound! Chaucer demonstrates that by what he doesn't say. That is why no human or environmental limitations are presented. He says nothing of a pleasant countryside. There is no mention of weather or road conditions. They never pass through a town. They never stop to eat or rest. They interact with no one outside their group. Nothing invalidates their celestial existence. Though an actual journey from London to Canterbury would have taken several days, the poet portrays Time as one symbolic day.
     Action found in the Tales is not to be confused with activities of that day. The stories are not the journey. The function of each story, I'm sure, is to aid in confirming the hidden identity of the storyteller. We'll talk about that sometime.
     But next we'll look into what is predicted as Time ends.
