Haudh-en-Elleth by Alan Lee

Haudh-en-Elleth was the grave of Finduilas of Nargothrond that stood near the Crossings of Teiglin on the western borders of the Forest of Brethil.[1] Túrin would not allow Orcs to draw near to the mound, so they soon feared and avoided the place.[2] On one of his forays to battle Orcs near the Crossings, Túrin discovered Niënor his sister (whom he did not know) upon the mound, naked and cowering from a storm.[3] Later Túrin met Mablung at the mound and learned that Niënor was indeed his sister.[4]


Haudh-en-Elleth is a Sindarin name glossed as "Mound of the Elf-maid" or "mound (grave) of the Noldorin maid", from haudh ("funeral mound") + en ("of the") + Elleth ("Elf-maid").[5]:141 An early form was Haudh-en-Ellas.[5]:97
