Welcome to The Encyclopedia of Arda

The Encyclopedia of Arda is a personal project - a tribute to and a celebration of the works of J.R.R. Tolkien. The site is evolving into an illustrated hypertext encyclopedia of Tolkien's realms and peoples. It already contains about four thousand entries, and we're constantly adding new entries and expanding existing ones.

Inside the encyclopedia

The Encyclopedia of Arda contains thousands of articles covering topics from J.R.R. Tolkien's world, some brief, some lengthy and some containing detailed essays and discussions.

You'll also find a selection of interactive tools, including a chronicle to help you explore Tolkien's fictional history, and calendar to translate dates and events, a lexicon of names, a glossary of old and rare words, and much more.

Context and approach

The content of the Encyclopedia is written in the same context as Tolkien himself used; he presented himself simply as a translator, rather than originator of the tales. Hence, we try to describe his world from a 'historical' rather than a literary perspective, though sometimes it's useful to explore ideas in their wider context. Where relevant, therefore, you'll also find a few references to Tolkien's life or opinions, or to real historical or mythological parallels to events in his universe.

About the name Arda

Arda was the name given by the Elves to their world and all it contained, and so 'Encyclopedia of Arda' seemed a peculiarly apt title for this project.

Special thanks

Thanks to all those who've e-mailed us over the years with their suggestions, corrections, ideas and just general support.

But the real Special Thanks, though, belong to the memory of J.R.R. Tolkien for his extraordinary and unparalleled creation.

River Greylin

One of the Anduin’s two source-rivers

In the north of Middle-earth, near the western end of the long range of the Grey Mountains, three streams rose near one another on the mountains' southern side. One of these - the easternmost - flowed away southeastwards to enter Mirkwood and form the Forest River. The other two ran down southwards through the mountains and on to the grassy plains beyond. After some forty miles, the two branches joined together to form a wider stream.

The name Greylin was given to the river by the Men of the Éothéod, who dwelt in the northern plains for several centuries during the Third Age. The name was said to mean 'grey torrent' in their tongue, presumably referencing its sources in the Grey Mountains to the north. These Men built their township of Framsburg at the southern end of the river, where it met another stream, the Langwell, that flowed down from the Misty Mountains to the west.
