The other day, my friend Jaym posted a link on Facebook to the amazing Evan Palmer's homage to Tolkien. Palmer has illustrated the Ainulindalë, which is the elvish for "Music of the Ainur", or, for the layman, it's the creation story of Middle-earth.
You don't need to understand much about Middle-earth to understand the Ainulindalë, but it will add relevance to fans of the movies to understand that the Melkor that is in the Ainulindalë would later become Morgoth.
"Melkor was the most powerful of the Ainur, but turned to darkness and
became Morgoth, the definitive antagonist of Arda from whom all evil in the
world of Middle-earth ultimately stems. Sauron, one of the Maiar of Aulë,
betrayed his kind and became Morgoth's principal lieutenant.
Morgoth was the principal agent of evil in 'The Silmarillion', and his influence
lingered in the world even after he was cast from the world into the outer
void. Morgoth's example provided later ages a cautionary tale against pride,
wrath, envy, lust for power, and greed — and the destruction these visit upon
oneself and others."
But none of that is needed to enjoy the gorgeous illustrations, and the lovely myth that Tolkien has given us, which can be found here.
