Who told The stories in the Canterbury Tales?

In the Canterbury Tales a group of pilgrims are traveling to the shrine of St Thomas a Becket at Canterbury Cathedral.

The pilgrims decide that each of them will tell two stories on the way there, and two more on the way back - taking turns.

Chaucer never completed his work, so most of the pilgrims tell only one tale - but we find out a lot about the sort of person telling the story by the kind of story they choose, and also by how they tell it.
