The New and the Old - a comparison of Tokienīs original Sketch with my new Map
In this new page, there is the original Tolkien map (well, ... draft of a map), at the bottom of the page. The contents of this map are the same than in the one I linked previously. This map (Map 5) is in the Ambarkanta, toghether with other 4 maps.
As Christopher Tolkien says, JRR Tolkien draw them at an early stage of his mithology, and he never changed them to fit with its later evolution. Therefore, they are 'reliable' to a certain extent .., but it is true that they were drawn by Tolkien himself [img]smilies/wink.gif[/img]
