In many ways one of the most remarkable
demonologies is that presented in the Avesta (q.v.), the sacred
book of the Mazdean religion of Zoroaster. In this ancient
religion, which unlike that of the Assyrians, still exists in the
Parsee community, the war between light and darkness, good and
evil comes into greater prominence. Over against the good God,
Ahura Mazda, with his hierarchy of holy spirits, there is arrayed
the dark kingdom of demons, or daevas, under Anro Mainyus
(Ahriman), the cruel Evil Spirit, the Demon of Demons (Daevanam
Daeva), who is ever warring against Ahura Mazda and his faithful
servants such as Zoroaster.
It may be remarked that the name of Daeva is an instance of that
change from a good to a bad sense which is seen in the case of
the Greek word daimon. For the original meaning of the word is
"shining one", and it comes from a primitive Aryan root
div, which is likewise the source of the Greek Zeus and the Latin
deus. But while these words, like the Sanskrit deva, retain the
good meaning, daeva has come to mean "an evil spirit".
There is at least a coincidence, if no deeper significance, in
the fact that, while the word in its original sense was
synonymous with Lucifer, it has now come to mean much the same as
devil.
There is also a curious coincidence in the similarity in sound
between daeva, the modern Persian dev, and the word devil.
Looking at the likeness both in sound and in significance, one
would be tempted to say that they must have a common origin, but
for the fact that we know with certainty that the word devil
comes from diabolus (diabolosdiaballein) and can have no
connection with the Persian or Sanskrit root.
Although there are marked differences between the demons of the
Avesta and the devil in Scripture and Christian theology (for
Christian doctrine is free from the dualism of the Mazdean
system), the essential struggle between good and evil is still
the same in both cases. And the pictures of the holiness and
fidelity of Zoroaster when he is assailed by the temptations and
persecutions of Anro Mainyus and his demons may well recall the
trials of saints under the assaults of Satan or suggest some
faint analogy with the great scene of the temptation of Christ in
the wilderness. Fortunately for English readers, a portion of the
Vendidad (fargard xix), which contains the temptation of
Zoroaster, has been admirably rendered in a doctrinal paraphrase
in Dr. Casartelli's "Leaves from my Eastern Garden".
The important part played by the demons in the Mazdean system may
be seen from the title of the Vendidad, which is the largest and
most complete part of the Avesta, so much so that when the sacred
book is written or printed without the commentaries it is
generally known as Vendidad Sade which means something that is
"given against the demons - vidaevodata, i.e. contra
daimones datus or antidaemoniacus.
