a) King Horn
anonymous
Rymenild is speaking to Horn
Rymenild is telling Horn about the dream she has had, after they decide to get married and before he leaves for the first time

The dream and its theme of loss resound throughout King Horn.  It is meant to mirror the relationship of Horn and Rymenild and her fears of not ‘catching' him, as she loves him.  In many places they are separated in the poem.  First Horn must leave Westnesse because of Fykenyld's lies.  Horn does not return for seven years and is late when he does.  He finds Rymenild already married.  He then gets her back but again leaves to retake his homeland and while he is gone she marries again to Fykenyld.  Rymenild has cast her net to catch Horn, ‘The fyssh that Y wolde cheose'  She even sent messages to him but never got a reply.  This dream is both her fears of losing him and actual foreshadowing of his leaving in the future.
MORE:  the dream talks of fishing.  Later when he returns, Horn will pretend to be a fisherman.

b) Handlyng Synne
Robert Mannyng
First the narrator is speaking, then the people who were cursed by the priest speak to the priest, Robert.
This speech comes pretty near the end, when the year of dancing has ended but before Robert dies (as the dancers tell him he will) and before the narrator gives more details about their lives then his moral.

The priest Robert was also blamed by his son Azone, when the incident first occurred – specifically, after Azone had tried to save Ave from the circle and had ripped off her arm.  These events are important because the priest is being blamed for cursing the dancers in the first place.  The narrator told us at the start that this was a story against sacrilege, but the story ends up having at least two conflicting morals: 1) don't dance in the church yard, 2) don't get mad and curse people, because it will rebound on you.  Originally, it's made to seem that the ones who had sinned were the dancers, but at the end of the story Mannyng seems more eager to point out the priest's sin in being moved so hastily to anger:  the dancers live but Ave and the priest die.

c) The Five Joys of Mary
anonymous
narrator addresses readers
these are the opening lines

The last two lines give the reader a clue that this isn't a typical chanson d'aventure.  Later on, the poet goes onto elaborate on the idea of Mary as the perfect maiden all of us are seeking.  The poet is attempting to bring together secular and religious ideas of love – but also to show us the difference between them.  Your typical maiden doesn't do ALL of us good at once through secular love!  Throughout the poem, the poet will elaborate on why Mary may ‘do all of us good through her petitioning' by enumerating the five joys and how they affect the reader.

d) Pearl
anonymous
first the dreamer speaks to the Pearl maiden, then she replies to him
This comes about two thirds of the way through the poem, after the maiden has tried to explain her place in heaven to the dreamer, and before she lets him see the New Jerusalem across the river.

The Pearl maiden's warning that the dreamer (says God) may not enter the New Jerusalem because he is not pure, is proved true at the end of the dream after he tries to cross the stream into Paradise and has the dream and his fragile connection to his deceased daughter snapped away from him.  Also, near the start when he first arrived in the dream and met his daughter, the first thing he wanted was to join her, but she told him that he couldn't.  He keeps wanting to join her throughout the poem, and doesn't seem to understand when she keeps refusing.

e) The Book of the Duchess
Geoffrey Chaucer
the Knight dressed in Black is speaking, and the narrator is overhearing him.
This takes place while the Dreamer is on a hunt in his dream.  He comes upon a person in the forest who he notices is a knight.  He is very depressed and the Dreamer is trying to find out why.

The listener does not learn anything from this utterance but he still knows the black knight is very depressed.  This seems very surprising because it makes the listener seem very stupid.  This is done to get the black knight to speak about the good things about his wife and also to speak about the good things about his wife and also to eventually get him to say that his wife is dead without hiding behind literature or analogies.  By doing this is shows the reader some necessary steps that must be taken to go through a healthy process of mourning.

f) Prologue to Malory's Morte Darthur
William Caxton
The speaker is Caxton defending his reasons to publish Malory's work.
This comes right at the end, when Caxton is summing up his arguments.

Caxton is trying to provide reasons to read Malory's work.  He first claims that people kept asking him to publish it.  He then goes on to say that historical tales of great men can teach us how to live our lives.  He also defends against the criticism that Arthur is fictional.  He emphasizes that there is both good and bad in the text, and explains that the bad deeds are necessary to show what not to do.  He claims that the Morte Darthur will show readers how to live their lives.
