It occurs to me also that Malphas could conceivably be a refrence to the Magus (better known to us as Magi, as in the three wise men), a caste of Median astrologers/diviners/magicians. According to Funk and Wagnells many of their rituals (such as letting the dead rot in the open air) were incorporated into Zoroastrianism, and Zoroaster himself might have been a Magus, as the Greeks believed.
Pardon my ignorance, but where does that connection come into play? The only Malphas I've heard of is the builder-demon one can summon for hard labor, depicted as an anthropomorphic crow. In the context with which I'm familiar, he was one called upon to construct impregnable fortresses, as well as to teach his summoners how to breach their enemy's own ramparts. I've never heard of a connection to the Magi, though do elaborate if a well-documented one exists, this is interesting to note.
Personally I'd attribute the openly-rotting and festering dead to Eurynome, who in de Plancy's
Dictionnaire Infernal is described as the "prince of death," with a body covered in decaying sores and who feeds on decaying flesh. Granted, de Plancy's work was published in 1863, and obviously there are far older texts which have already been mentioned here. So take any references to the
Infernal with a pinch (or should I say circle?) of salt.
As for other CV monsters, it's possible to see potential inspiration behind even more basic enemies, such as Persephone. Wife of Hades' name notwithstanding, there's a Hungarian demon called the Liderc, who in addition to an incubus and ignis fatuus, can take the form of what is described as a "household helper." Sound familiar? Of course, in this context, it assumes the form of "a featherless chicken, which can arrive on its own or be hatched from an egg incubated under the armpit. It carries out tasks for its master. Unfortunately, it carries out tasks too quickly and efficiently and always wants more to do, until eventually it incessantly begs its master for new chores." This version of the Liderc can, however, assume a human form at will.
1I think it's interesting to note that the angel of death figure in Hinduism is called Mara(not to be confused with Yama, the Hindu
Lord of Death), and is less an evil being and more the embodiment of all that causes suffering, for such a thing must exist to balance out the good. It's only worth noting due to the similarities of the name of the death angel in Koranic and rabbnic lore. Fascinating how that happens, I think.
1"Bael (Baal- "lord" or "master")- in The Zohar, Bael is equated with the archangel Raphael. However, in the grimoires, and in the Wierus, Pseudo-Monarchia, he is a great king of the underworld serving in the eastern division of Hell and attended by 60 or 70 legions of devils. He manifests, when invoked, as a creature with 3 heads (toad, man, cat)."
He may have served as the inspiration for Asmodeus (the effigy demon representing Lust, as well as the chieftain demon lord in Judaism, respectively), who has three heads also (bull, ogre, ram). He rides a fire-breathing lion and has the legs of a cock. His name alone makes his connection to the ancient Persian demon of wrath, Aeshma, going even further back. The legs of the cock are also important, as that can also be traced back, to the Babylonians and their belief that the cock as a major divine entity of the night to whom sacrifice was made. That this reference exists serves to beef up the power this demon has. In Christian lore he is interchangeable with Sammael and therefore Lucifer himself. He's also the guy who stole Solomon's ring and had a field day trolling everybody.
1 2As odd a theory as this sounds, the Cave Troll's licking might be a reference to the (yes, this exists) foot-licking Palis of the Arabias, which snuck up on sleeping campers and licked the soles of their feet until somehow their blood was drained. Yeah, I don't understand this one either.
I'll post some more later, when I'm not so tired.
