Two stories...

Mary Rogers gives two vignettes of Lewis in Headington in her article "C.S. Lewis — God's Fool" in Oxford, the Journal of the Oxford Society, for November 1998:

"Jack never minded looking a fool in a good cause. My sister-in-law tells me that he used to attend an annual party in Headington where guests were expected to arrive, not exactly in fancy dress, but to suggest some topic the hostess had decided upon. After Jack's marriage to Joy, he brought her along, obviously much to her disgust. She had chosen not to represent some character in Poetry or Opera... Lewis (of course) represented Wotan, wearing a black eye-shade over one eye — without embarrassment.

"Another Lewis-the-fool story involved an elderly dog. Both brothers were animal lovers, and cared for each dog lovingly to his last breath. One, in its extreme old age (probably Baron or Mr Papworth, also known as "Tykes") became very difficult, as we all do, in time. It was one of the rare sights of Headington to see Jack feeding an animal who was sensitive about being seen eating, and would not eat on home territory. So Jack would walk in front holding the dog dish in one hand, and a spoon in the other, ladling the food backwards over his shoulder to the following shambling dog, the leader being quite unmindful of the passers by and their reactions, as long as the dog got fed."

Lamorak and the Queen Morgause of Orkney (Final)

The child lies unborn in the queen's womb;
unformed in his brain is the web of all our doom,
as unformed in the minds of all the great lords
lies the image of the split Table and of surreptitious swords.

I am the queen's servant; while I live
down my eyes the cliff, the carving, the winged things drive,
since the rock, in those fleet lids of rock's hue,
the sculpture, the living sculpture, rose and flew.

Lamorak and the Queen Morgause of Orkney (IV)

The eyes of the queen Morgause were a dark cavern;
there a crowned man without eyes came to a carved tavern,
a wine-wide cell, an open grave, that stood
between Caerleon and Carbonek, in the skirts of the blind wood.

Through the rectangular door the crowned shape went its way
it lifted light feet: an eyeless woman lay
flat on the rock; her arm was stretched to embrace
his own stretched arm; she had his own face.

The shape of a blind woman under the shape of a blind man
over them, half-formed, the cipher of the Great Ban,
this, below them both, the shape of the blatant beast matched,
his mouth was open in a yelp; his feet scratched.

Beyond them a single figure was cut in the rock;
it was hewn in a gyration of mow and mock;
it had a weasel's head and claws on hand and feet;
it twirled under an arch that gave on the city's street.

Lamorak and the Queen Morgause of Orkney (III)

When from the sea I came again to my stall
King Arthur between two queens sat in a grim hall,
Guinevere on his right, Morgause on his left
I saw in her long eyes the humanized shapes of the cleft.

She sat the sister of Arthur, the wife of Lot,
four sons got by him, and one not.
I heard as she stirred the seamews scream again
in the envy of the unborn bastard and the pride of canonical Gawaine.

I turned my eyes to the lords; they sat half-dead.
The young wizard Merlin, standing by me, said:
'Balin had Balan's face, and Morgause her brother's.
Did you not know the blow that darkened each from other's?

'Balin and Balan fell by mistaken impious hate.
Arthur tossed loves with a woman and split his fate.
Did you not see, by the dolorous blow's might,
the contingent knowledge of the Emperor floating into sight?

'Over Camelot and Carbonek a whirling creature hovered
as over the Adam in Eden when they found themselves uncovered,
when they would know good as evil; thereon it was showed,
but then they must know God also after that mode.'

Lamorak and the Queen Morgause of Orkney (II)

I had gone in summer at the king's word to explore
the coast of the kingdom towards the Pole; the roar
of the ocean beyond all coasts threatened on one hand;
on the other we saw the cliffs of Orkney stand.

Caves and hollows in the crags were filled with the scream
of seamews nesting and fleeting; the extreme theme
of Logres rose in harsh cries and hungry storms,
and there, hewn in a cleft, were hideous huge forms.

I remembered how the archbishop in Caerleon at a feast
preached that before the making of man or beast
the Emperor knew all carved contingent shapes
in torrid marsh temples or on cold crookt capes.

These were the shapes only the Emperor knew,
unless Coelius Vibenna and his loathly few,
squat by their pot, by the twisted hazel art
sought the image of that image within their heart.

Sideways in the cleft they lay, and the seamews' wings
everywhere flying, or the mist, or the mere slant of the things
seemed to stir them; then the edge of the storm's shock
over us obliquely split rock from rock.

Ship and sculpture shuddered; the crags' scream
mingled with the seamews'; Logres' convulsed theme
wailed in the whirlwind; we fled before the storms,
and behind us loosed in the air flew giant inhuman forms.

Lamorak and the Queen Morgause of Orkney (I)

Hued from the livid everlasting stone
the queen's hewn eyelids bruised my bone;
my eyes splintered, as our father Adam's when the first
exorbitant flying nature round creation's flank burst.

Her hair was whirlwind about her face;
her face outstripped her hair; it rose from a place
where pre-Adamic sculpture on an ocean rock lay,
and the sculpture torn from its rock was swept away.

Her hand discharged catastrophe; I was thrown
before it; I saw the source of all stone,
the rigid tornado, the schism and first strife
of primeval rock with itself, Morgause Lot's wife.

Why were the Rings of Power made, and what were their Powers?

The reason is tied to the regret the Elves had for the passage of time. The Elves were immortal and were fated to live as long as Middle-earth lasted. As such, the earth changed with the passage of time, and the Elves saw many things that were fair become destroyed and lost by the hurts of evil. Sauron, as tempter, awoke a desire in the hearts of Elves to heal the hurts of the earth and create a paradise on this side of the sea to compare to Valinor -- and to be its rulers; whereas in Valinor they were only subjects and below the Valar. The Rings of Power were primarily made to slow the passage of time and preserve their creations of beauty. Yet they had other powers as well.

Tolkien provides a revealing insight on to the nature of the Rings and their powers in one of his letters:

"The chief power (of all the rings alike) was the prevention or slowing of decay (i.e. 'change' viewed as a regrettable thing), the preservation of what is desired or loved, or its semblance - this is more or less an Elvish motive. But also they enhanced the natural powers of a possessor - thus approaching 'magic', a motive easily corruptible into evil, a lust for domination. And finally they had other powers, more directly derived from Sauron... such as rendering invisible the material body, and making things of the invisible world visible."
[The Letters of J.R.R. Tolkien #131]

The Rings were not made as instruments of war or domination; they could not create lightning bolts or hail storms. Yet, they conferred powers commensurate with that of the user; a Great Ring in the hands of a weak and lesser person could not work effects to the extent of the wise or great. Notice Galadriel's words to Frodo in Lothlórien:

"Did not Gandalf tell you that the rings give power according to the measure of each possessor? Before you could use that power you would need to become far stronger, and to train your will to the domination of others." [The Fellowship of the Ring]

The Elves used the Three Rings to create "islands of timeless beauty" and guard them against the passage of time and evil. Their use can be seen at work at various points:

~ Elrond used the power of his ring, Vilya, to cause the flood of the river Bruinen when the Nazgûl tried to capture Frodo.

~ Galadriel used the power of her ring, Nenya, to keep a guard on Lothlórien so that none could enter without her leave.

~ Gandalf used the power of his ring, Narya, to kindle the hearts and spirits of the enemies of Sauron to do great deeds. And quite possibly to assist him in his battle to the death with the Balrog.

But the use of the Elven Rings was possible only after Sauron was defeated in the Second Age and his Ring taken and assumed lost. If Sauron regained the One, then all the works of the Elves and the use of their Rings would be subject to the evil will of Sauron.

What were the changes...

What were the changes made to "The Hobbit" after
"The Lord of the Rings" was written, and what motivated them?

[This question refers to the major revisions made to the Gollum chapter, "Riddles in the Dark", not to the multitude of minor changes made elsewhere.]

In the original 1937 edition of "The Hobbit" Gollum was genuinely willing to bet his ring on the riddle game, the deal being that Bilbo would receive a "present" if he won. Gollum in fact was dismayed when he couldn't keep his promise because the ring was missing. He showed Bilbo the way out as an alternative, and they parted courteously.

As the writing of LotR progressed the nature of the Ring changed. No longer a "convenient magical device", it had become an irresistible power object, and Gollum's behaviour now seemed inexplicable, indeed, impossible. In the rough drafts of the "Shadow of the Past" chapter Gandalf was made to perform much squirming in an attempt to make it appear credible, not wholly successfully.

Tolkien resolved the difficulty by re-writing the chapter into its present form, in which Gollum had no intention whatsoever of giving up the Ring but rather would show Bilbo the way out if he lost. Also, Gollum was made far more wretched, as befitted one enslaved and tormented by the Ruling Ring. At the same time, however, Bilbo's claim to the Ring was seriously undercut.

There are two issues involved, well summarised in the Prologue: "The Authorities, it is true, differ whether this last question was a mere 'question' and not a 'riddle' ... but all agree that, after accepting it and trying to guess the answer, Gollum was bound by his promise" (FR, 21). Thus, it was Bilbo's winning of the game that was questionable. Given that he had in fact won, albeit on a technicality, he was fully entitled to the prize, which, in the old version, was the ring. In the new version, however, he had no claim to the Ring at all, whether he had won or not, because the Ring was not the stake of the game.]

The textual situation thus reached was that there now existed two versions of the episode. Tolkien deftly made this circumstance part of the story by suggesting that the first time around Bilbo was lying (under the influence of the Ring) to strengthen his claim. (Bilbo had written this version in his diary, which was "translated" by Tolkien and published as "The Hobbit"; hence the error in the early editions, later "corrected".) This new sequence of events inside the story is laid out clearly in "Of the Finding of the Ring" (Prologue) and is taken for granted thereafter for the rest of the story (e.g. in "The Shadow of the Past" and at the Council of Elrond).

"The Hobbit" as now presented fits the new scenario remarkably well, even though Tolkien, for quite sound literary reasons, left this entire matter of Bilbo's dishonesty out (it was an entirely irrelevant complication which would have thrown everything out of balance). The present attempt to step back and view the entire picture is made more involved by the fact that there were two separate pieces of dishonesty perpetrated by Bilbo.

The first, made explicit, was that when he initially told his story to Gandalf and the Dwarves he left the ring out entirely -- this no doubt was what inspired Gandalf to give Bilbo the "queer look from under his bushy eyebrows" (H, 99). Later, (after the spider episode) he revealed that he had the Ring, and it must have been at this point that he invented the rigmarole about "winning a present" (an incredible action, given the circumstances). There is, however, no hint in the text of this second piece of dishonesty (as noted above, it would have been a grave literary mistake).

Readers are therefore given no indication that when "Balin ... insisted on having the Gollum story... told all over again, with the ring in its proper place" (H, 163) that Bilbo didn't respond with the "true" story, exactly as described in Ch V. In this regard, "Of the Finding of the Ring" in the Prologue is a necessary prelude to LotR.
