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.

The great lake that fed the Falls of Rauros

The great oval lake that lay in the mid-course of the River Anduin, which entered it through the Gates of Argonath to the north and then emptied in the rushing falls of Rauros some twenty miles to the south. The lake, whose name is translated as 'Mist-cool Water', was surrounded on all sides by the grey stony hills of the Emyn Muil. Most important among its surrounding hills were two that lay at its southern end, the famous Amon Hen and Amon Lhaw, the Hills of Sight and Hearing.

Also near its southern end was the lake's only island, named Tol Brandir in Elvish, that Men called the Tindrock. Its steep rocky sides made landing on the island nearly impossible, and legend said that no Man had ever stood on the Tindrock Isle.
