ABSTRACT This article investigates patterns of scholarly patronage relating to Khalaf b. Aḥmad (r. 963–1003 ce, d. 1009), placing them in their broader Saffarid and regional contexts. Of the extant works we can link to Khalaf, a little studied medical text, the Kunnāsh, is arguably the single most insightful in exposing Khalaf as patron and in placing him in the context of earlier and later Saffarid and Sistani support for the medical sciences. The article argues that Khalaf being both an author of a work on dream interpretation and a patron of medical literature is not a combination unique to him. In fact, it fits rather well with the pattern of patronage activities of the Khwārazmshāhs in the early eleventh century. This study suggests that Eastern Iranian areas may have developed a greater degree of self-definition as intellectual centres of scholarship than previously acknowledged, and that this will have happened both through competition with one another and by retelling their legacies of past patronage.
