Abstract (source: JSTOR):
The frontiers of the medieval Nubian states often evoke the riverine landscape of the Nile. For example, in a 2002 overview, Derek Welsby wrote, “virtually no sites [of medieval Nubia] are known outside the Nile valley.” This chapter presents new evidence concerning the presence of medieval Nubia west of the Nile, which in turn bears on locating the enigmatic land (or province) of Ṭari’ mentioned in medieval texts.
