We are similarly unfortunate wit the literary evidence wich the late Kesravi had collected from Persian Works: There is noting conclusive . The most considerable is a set of 14th cerntury
dialect quatrains from Ardabil; but Ardabil is merely on the fringe from Azebaijan,close to Taleş,
and the dialect of ehese quatrains has been shown to be akin to talishi. In short, with all the dialects
we have considered here, of Taliş, Harzan, Khalkhal, and Takistan, we remain on the threshold of
Azerbaijan; but of the language once spoken in Azerbaijan itself we know nothing.
