EREBUS

 EREBUS
"I have haunted the tombs of the ages,
I have flown on the pinions of fear
Where the smoke-belching Erebus rages,
Where the jokulls loom snow-clad and drear;
And in realms where the sun of the desert consumed what it
never can cheer."
H.P. Lovecraft, Nemesis

"E′rebos, a son of Chaos, begot Aether and Hemera by Nyx, his sister. Hyginus and Cicero  enumerate many personifications of abstract notions as the offspring of Erebos. The name signifies darkness, and is therefore applied also to the dark and gloomy space under the earth, through which the shades pass into Hades." 
Sir William Smith, Dictionary of Greek and Roman Biography and Mythology

"The name Erebos was also used for the dismal, netherworld realm of Haides."

"Erebus was the primeval god of darkness, consort of Nix, whose dark mists enveloped the edges of the world, and filled the deep hollows of the earth."
Aaron J. Atsma, The Theoi Project: Greek Mythology 

INVISIBLE DAEMON

INVISIBLE DAEMON

"That resound with hysterical cries;
With the moans of invisible daemons, that out of the green waters rise."

H.P. Lovecraft, Nemesis

"It was in vain that I begged of some of the men to come near and convince themselves by touch of the existence in that room of a living being which was invisible."

"As well as we could make out by passing our hands over the creature’s form, its outlines and lineaments were human.  There was a mouth; a round, smooth head without hair; a nose, which, however, was little elevated above the cheeks;"

"It was shaped like a man—­distorted, uncouth, and horrible, but still a man.  It was small, not over four feet and some inches in height, and its limbs revealed a muscular development that was unparalleled.  Its face surpassed in hideousness anything I had ever seen.  Gustav Dore, or Callot, or Tony Johannot, never conceived anything so horrible.  There is a face in one of the latter’s illustrations to Un Voyage ou il vous plaira, which somewhat approaches the countenance of this creature, but does not equal it.  It was the physiognomy of what I should fancy a ghoul might be.  It looked as if it was capable of feeding on human flesh."

Fitz-James O'Brien, What Was It?
