My original tumblr post was here. This image is Coitus Vilius by Trollskog-Studio. The Studio appends the appropriate text:
Coïtus Vīlis
or,
BEAUTY & THE BEAST AS SEEN THROUGH LOVECRAFTIAN LENSES“When it come to matin’ with them toad-lookin’ fishes, the Kanakys kind o’ balked, but finally they larnt something as put a new face on the matter. Seems that human folks has got a kind a’ relation to sech water-beasts – that everything alive come aout o’ the water onct an’ only needs a little change to go back agin. Them things told the Kanakys that ef they mixed bloods there’d be children as ud look human at fust, but later turn more’n more like the things, till finally they’d take to the water an’ jine the main lot o’ things daown har.”
– H.P. Lovecraft, ‘The Shadow over Innsmouth’
