"But the waters of Tarn Aeluin were held in reverence, for they were clear and blue by day and by night were a mirror for the stars..."
Quenta Silmarillion, "Of Beren and Lúthien"

Aeluin, sometimes referred to as Tarn Aeluin,[1] was a clear blue mountain lake in the eastern highlands of Dorthonion, southwest of Ladros.[2] It was situated among wild heather hills, themselves surrounded by trackless and uninhabited forests and highland plains of heather.[1]


[edit] History

It was said to have been hallowed by Melian the Maia.[1]

There Aegnor saw the reflection of Andreth and fell in love with her.[3]

Barahir's Outlaw Band hid from Morgoth's forces after the Dagor Bragollach and made their lair at Aeluin. There they remained hidden until betrayed by Gorlim.[1]

[edit] Etymology

Aeluin means "Blue Lake" in Sindarin (from ael = "lake, pool" and luin = "blue"). Tarn is an archaic English word meaning "mountain lake".

[edit] Other versions of the legendarium

According to the text in "The Complaint of Mîm the Dwarf", it is implied that Mîm, one of the last Petty-dwarves, used to live near Tarn Aeluin until Men came and drove him out, stealing his belongings in the process.[4]
