Silmarillion

J.R.R. Tolkien's posthumously published mythological history of Middle-earth (1977, edited by Christopher Tolkien). Variant title of The Silmarillion — the creation myth of Ea, the Music of the Ainur, the fall of Morgoth, and the heroic ages of the First Age.

Provided the deep mythological and cosmogonical substrate for all of Tolkien's Middle-earth. The Music of the Ainur (Ainulindale) is a Tolkienian theodicy and a model of subcreation; the Quenta Silmarillion is heroic tragedy at mythic scale.
