Long acknowledged as a master of nightmarish visions, H. P. Lovecraft established the genuineness and dignity of his own pioneering fiction in 1931 with his quintessential work of supernatural horror, At the Mountains of Madness. The deliberately told and increasingly chilling recollection of an Antarctic expedition’s uncanny discoveries – and their encounter with untold menace in the ruins of a lost civilization – is a milestone of macabre literature. At the Mountains of Madness is a very good introduction to Lovecraft’s mythology of the Old Ones and the glories and horrors that preceded humankind and that still linger in places. It is a good novella on it’s own, and helpful to understanding events and creatures in his other works.
