During what decade did J.R.R. Tolkien use mythopoeia in his literary works?
The Silmarillion The Silmarillion is a collection of mythopoeic works by English writer J. R. R. Tolkien, edited and published posthumously by his son, Christopher Tolkien, in 1977, with assistance from Guy Gavriel Kay. "The Silmarillion", along with J. R. R. Tolkien's other works, forms an extensive, though incomplete, narrative that describes the universe of Eä in which are found the lands of Valinor, Beleriand, Númenor, and Middle-earth within which "The Hobbit" and "The Lord of the Rings" take place.
Eriador Eriador is a large region in J. R. R. Tolkien's fictional world of Middle-earth. The Shire, a land which became famous in the Third Age and again in modern times, was located in the central west of this region. The region was also called the Lone-lands, a translation of "Eriador".
