A leading Spanish talmudist, Moses ben Nahman, also known
as Nahmanides and by the acronym Ramban (Rabbi Moses
hen Nahman), was the intellectual and communal leader of
Catalan Jewry during a crucial period. His writings reflect a
synthesis of the dialectical tradition of the tosafists in northern
France with the geonic-Andalusian traditions of analytical
scholarship and literary culture. The broad scope of
Nahmanides' learning enabled him to provide a measure of
stability in the face of conflicts that arose from within Jewish
society and from the Christian world as well. (from Introduction)
