The land ruled by Thingol and Melian, so called because it was protected by the Girdle of Melian (S/97). This name was translated “Land of the Girdle” (S/97) or more literally “Land of the Fence” (WJ/370), and was a combination of dôr “land” and iath “fence” (SA/dôr, iâth).
Conceptual Development: In the earliest Lost Tales, this land was first called G. Dor Athro “Land Beyond” (LT2A/Artanor), revised to G. Doriath (LT2/41), the form it retained thereafter. In The Etymologies from the 1930s, N. Doriath was translated “Land of the Cave”, with the second element being a lenited form of N. gath “cavern” (Ety/GAT(H)). The association of the name with the Girdle of Melian first appeared in Silmarillion revisions from the 1950s-60s (WJ/16).
