The Fustat al-‘adala: a Unique Manuscript on the Religious Landscape of Medieval Anatolia

Abstract

The particularities in the political development of medieval Anatolia after the arrival of the Seljuq Turks in the eleventh century resulted in a singular scenario in which a long but steady process of Islamization transformed medieval Anatolia with the majority Christian population into a mostly Muslim territory by the end of the fifteenth century. However, this process of conflict and accommodation affected not only the different religions present in the peninsula but also those confessions that coexisted and competed with each another within each of these religions. The religious diversity of the 13thto 15thcent. Anatolia has also reflected its textual production. Several significant works onkalamandfiqh, in addition to a variety of Sufi texts, were produced during this period. These works often deal with dogma, practices or traditions of their religious confession. But, generally, they do not offer much information on other religious confessions. The manuscript held at the Bibliothèque National de France (Supplément Turc 1120) contains a work which has been identified by Osman Turan as theFustat al-‘adalaand attributed to a certain Muhammad b. Muhammad al-Khatib. The uniqueness of this work is that a part of it is occupied with describing the different ‘heresies’ that were present in Anatolia at the time when the author lived, which appears to be during the lifetime of the last Seljuq Sultan of Rum, Ghiyath al-din Mas‘ud (d. 1308 AD). This introduction will look at this manuscript from both a codicological and thematic perspective. On the one hand, I will discuss certain aspects related to the production of the codex, its authorship and potential patronage. While on the other, the section on heresies contained in the text will be examined to explore what this work can tell us about the religious environment of medieval Anatolia.
