My expertise in not in the
maps (though I once noticed that there is a “Nargil Pass” between
Mordor and South
Gondor (or northern
Harad or western Khand) at the source of the
Harnen River in the southern
Mountains of Mordor).
Are you talking about the “Second
Map” discussed and reproduced in the chapter at the end of
War of the Ring? My understanding of this text was that JRR
Tolkien used the “First Map”, now “limp, torn, wrinkled, stained, and rubbed,” to write the first half of
Return of the King (“Book V of
The Lord of the Rings”).
I had to reread this chapter. I suppose you are correct, that JRR Tolkien made himself a larger map for this purpose, different from the “First Map”. No, I have never seen another map like that other than the published versions in
The Lord of the Rings or
Return of the King.
Christopher Tolkien says he redrew the Second Map “in squares of 2 cm. side (= 100 miles), the squares being lettered and numbered according to the First Map.” My bet would be that the original “Second Map” likely had major grids are at one-inch distances with fainter marks at tenths of an inch: Such engineering graph paper used to be quite commonly sold at American university bookstores forty years ago in both letter (8½ inch x 11 inch) and ledger (11 inch x 17 inch) sizes, typically with light green lettering and gridding; I suspect it was also common at English universities before the UK changed to metric in 1965.
I have seen reproductions of the large map of northwestern
Middle-earth from
Lindon to
Umbar with lots of JRR Tolkien’s scribbling on it. I think it is kept at Marquette University. But I’ve not seen a reproduction of an original “Second Map” (other than Christopher Tolkien’s published version) with detail of Gondor and Mordor.
So if I understand you correctly, Akhôrahil, there is a “First Map” that consists of the big view of northwestern Middle-earth from Lindon to Umbar, a “Second Map” with close-in details of Gondor and Mordor (to better write the second half of the story) that Christopher Tolkien has redrawn for
War of the Ring, and a pair of “Third Maps” (one large scale and one detailing Gondor and Mordor) for the published version of
Lord of the Rings. Is that right?
In any case, the Harnen River was well out of the theater of action in
Lord of the Rings, is it not?
