Furthermore the description of patriarchal age itself is made possible by the
survival, of what the writers of the considered to have been patterns typical
of the patriarchal age, into these later ages.
The patriarch stories project in fact in a quite anachronistic manner a
halfnomadic society as surviving in more desertic regions of the Sinai and
the Arabian peninsula. It is to be pointed that the patriarchs where rather
something as "displaced sedentary people" seeking new settling land in a
region where land was already settled than genuine nomadists.
Refferences to the Kasdim, et al, invading Arabia, or of El worship in Teman,
pushes the date rather into a late period, post 8th century. The most
probable period might be late Babylonian.
