Aiks, I am wondering if substituting
stone for
rock in the composite
rock-garden might help? In this earlier story a gardener makes a
rock garden from some old stones and some commonplace flowers. We could just as well say that the gardener makes a
stone garden. Now we can turn to the usual Tolkien texts, where stones feature a lot.
You may recall that the older generation of philologists at Oxford deemed
ond the aboriginal (pre-Celtic) word for stone? Or that Gondor first appeared in the drafts of
The Lord of the Rings as the land of Ond, realm of the stone-men? And of course the city of seven towers has its own Seeing Stone, one of seven Elvish stones that figure in this story. So the idea of a Stone Garden - what the gardener in the earlier short story makes with the old stones - resonates quite deeply with Númenórean and Elvish elements of this other (longer) story of J.R.R. Tolkien. (Of course, this is even more the case once the old stones are gathered into a tower, in the second allegory.)
Here are a few quotations from 'On Fairy-stories'. (My emphasis)
Faerie contains many things besides elves and fays, and besides dwarfs, witches, trolls, giants, or dragons: it holds the seas, the sun, the moon, the sky; and the earth, and all things that are in it: tree and bird, water and stone, wine and bread, and ourselves, mortal men, when we are enchanted.
Fantasy is made out of the Primary World, but a good craftsman loves his material, and has a knowledge and feeling for clay, stone and wood which only the art of making can give.
It was in fairy-stories that I first divined the potency of the words, and the wonder of the things, such as stone, and wood, and iron; tree and grass; house and fire; bread and wine.
And I especially draw your attention to this long passage (divided into two parts), which seems to me to touch directly on the kind of considerations that attended the design of Tolkien's two short stories about
Beowulf.
The radical distinction between all art (including drama) that offers a visible presentation and true literature is that it imposes one visible form. Literature works from mind to mind and is thus more progenitive. It is at once more universal and more poignantly particular. If it speaks of bread or wine or stone or tree, it appeals to the whole of these things, to their ideas; yet each hearer will give to them a peculiar personal embodiment in his imagination.
Should the story say “he ate bread,” the dramatic producer or painter can only show ”a piece of bread” according to his taste or fancy, but the hearer of the story will think of bread in general and picture it in some form of his own. If a story says “he climbed a hill and saw a river in the valley below,” the illustrator may catch, or nearly catch, his own vision of such a scene; but every hearer of the words will have his own picture, and it will be made out of all the hills and rivers and dales he has ever seen, but especially out of The Hill, The River, The Valley which were for him the first embodiment of the word.
