Taeglin in its pass by Cabed-en-Aras, by Alan Lee
General Information
LocationSouth of Ered Wethrin and Brethil
Descriptiontributary of Sirion

The Taeglin was a river in Beleriand, a tributary of Sirion.


It rose in the Ered Wethrin and flowed southeast through Brethil to join Sirion on the borders of Doriath. It had three minor tributaries: Glithui, Malduin[1] and Celebros.[2]

In its pass by the southeast of Brethil, it descended through the Ravines of Taeglin that skirted the eaves of the Forest. Further south, the river could be forded at the Crossings of the Taeglin, near the western border of Brethil. A road ran through it from Nargothrond to Minas Tirith.


The element taeg means "boundary".[3]

In the Etymologies the name appears in its earlier form "Taiglin" and its second element appears to be lin "pool".[4]

Other versions of the legendarium

In earlier writings, the river was called Teiglin. As revealed in the The History of Middle-earth series, the rivername should actually have been spelt Taeglin ("Boundary River").[3] This was a relatively late change which was not adopted into the published The Silmarillion, which uses the old name, as does The Children of Húrin.
