Tabbaa’s Transformation offers an innovative approach to understanding the profound changes undergone by Islamic art and architecture during the often neglected Medieval Islamic period.  Examining devices such as calligraphy, arabesque, muqarnas, and stonework, Tabbaa argues we propagated in a moment of confrontation and facilitated the re-emergence of the Sunni Abbasid caliphate in a more orthodox image.  Tabbaa offers a timely and thought-provoking alternative to conventional essentialist, positivist and ethno-narrative interpretations of Islamic art.
