This is Bergaigne's allegorical mysticism run mad.
At such perversion of reasonable criticism is the exegesis of the Veda arrived in one direction.

But in another it is gone astray no less, as misdirected by its clever German leader.

In three volumes[21] Brunnhofer has endeavored to prove that far from being a Brahmanic product, the Rig Veda is not even the work of Hindus; that it was composed near the Caspian Sea long before the Aryans descended into India.

Brunnhofer's books are a mine of ingenious conjectures, as suggestive in detail as on the whole they are unconvincing.

His fundamental error is the fancy that names and ideas which might be Iranian or Turanian would prove, if such they really could be shown to be, that the work in which they are contained must be Iranian or Turanian.
