"Iä! Shub-Niggurath! The Black Goat of the Woods with a Thousand Young!" ~ H. P. Lovecraft, "The Whisperer in Darkness"
This image tortured mea little, and took quite a long time. I'm not sure if it's right, but I can't bear to be in labour anymore. Lovecraft never described her beyond hinting at her role as a fertility goddess, and describing her as an "evil cloud-like entity". Attempting to illustrate a Mythos being as something more than a mere physical manifestation is difficult at best, but an interesting challenge.
