EURYNOMOS (or Eurynomus) was the netherworld Daimon (spirit) of rotting corpses, who stripped the flesh from the bones of the dead. He was probably connected with with the creatures which fed on corpses such as flies, maggots and vultures. Eurynomos was depicted with black-blue skin and wearing a vulture's-hide cloak.

EURY′NOMUS (Eurunomos), a daemon of the lower world, concerning whom there was a tradition at Delphi, according to which, he devoured the flesh of dead human bodies, and left nothing but the bones. Polygnotus represented him in the Lesche at Delphi, of a dark-blue complexion, showing his teeth, and sitting on the skin of a vulture. (Paus. x. 28. § 4.)

Pausanias, Description of Greece 10. 28. 7 (trans. Jones) (Greek travelogue C2nd A.D.) :
"[Description of a painting of the Underworld by Polygnotos C5th B.C. at Delphoi :] Eurynomos, said by the Delphian guides to be one of the daimones of Hades, who eats off all the flesh of the corpses, leaving only their bones. But Homer’s Odyssey, the poem called the Minyad, and the Returns, although they tell of Haides and its horrors, know of no Daimon called Eurynomos. However, I will describe what he is like and his attitude in the painting. He is of a colour between blue and black, like that of meat flies; he is showing his teeth and is seated, and under him is spread a vulture’s skin."
