Well I've finished
"Ayesha: The Return of She" (1905)
I'm sure I've re-read
She in the last few years, but Ayesha I probably read just the once when I was fifteen or sixteen, so it's been a while. All I remembered was an unlikely-shaped mountain and a battle towards the end.
Anyway, I enjoyed the first two thirds or so, consisting mainly of the travels and adventures of Leo and Holly searching for the mountain of their vision. Haggard, like Tolkien, has a great feel for landscape and so the journey was never dull. Sadly I found much of the last third, after they've reached their destination a little tedious and the various dialogues with Ayesha, for the most part, uninteresting.
One particular point of interest for me, which I'm sure will have been noted by Tolkien researchers, including, I expect, yourself
@Extollager : this passage is very reminiscent of The Black Riders/Elrond/Glorfindel at the Ford of Bruinen......
SPOILER
Leo and Holly have been pursued by the pack of Death Hounds unleashed by the crazed Khan. They have made it to a river (about a hundred yards wide), though Holly is painfully wounded in his right arm from a bite, and have managed to cross to a small island about thirty yards out, where they've collapsed and fallen asleep. Leo has a dream, though subsequent events show this not to have been a dream.
"he heard those accursed death-hounds in full cry. Nearer and nearer they came...... Then suddenly a puff of wind brought the scent of us upon the island to one of them which lifted up its head and uttered a single bay. The rest clustered about it, and all at once they made a dash at the water....
Giving tongue as they came, half-swimming and half-plunging, the hounds drew near to the island where we slept. Then suddenly Leo saw that we were no longer alone. In front of us, on the brink of the water, stood the figure of a woman clad in some dark garment. He could not describe her face or appearance, for her back was towards him. All he knew was that she stood there, like a guard, holding some object in her raised hand, and that suddenly the advancing hounds caught sight of her. In an instant it was as though they were paralysed by fear - for their bays turned to fearful howlings. One or two of those that were nearest to the island seemed to lose their footing and be swept away by the stream. The rest struggled back to the bank, and fled like whipped curs. Then the dark commanding figure, which in his dream Leo took to be the guardian Spirit of his Mountain, vanished."
Later they are told that the river marks the boundary of Ayesha's realm and entering it is forbidden.
There are obvious parallels here. Leo and Holly are in desperate straits. One of them is wounded (as was Frodo). Their terrible pursuers enter a river protecting the realm of someone with special powers (Rivendell and Elrond) and it seems to be all over for Leo and Holly. A mysterious figure intervenes. One or two of the pursuers are swept away, the others flee. The mysterious figure had held some object in her raised hand, paralleling Glorfindel (and others) holding flaming branches. Note also the acute sense of smell of the pursuers.
Anyway.
I've now located
"Allan and She" and will probably make a start on it in the next few days.
