A few years ago I offered an assessment of the Pate “Chronicles” as a tradition-based source for the history of the East African coast. That paper drew on recensions and versions that were readily available at that time to researchers interested in their historiography. Reasons of length and scope, cited at the end of the paper, restricted discussion to Sultan Fumo Madi b. Abu Bakr and his predecessors (Sultan nos. 1-24), that is to say, up to the time of the Battle of Shela, ca. 1807-13. To reiterate, in that paper I established the following points:
(1) All recorded versions appear to have been based on an oral tradition that was extant in the mid- to late nineteenth century among Nabahani family members. The existence of a “Book of the Kings of Pate,” mentioned by Werner and Prins, is problematic (see 3 below).
(2) Despite the number of versions of the Pate “Chronicles,” they appear to have actually come from only two informants, Bwana Kitini and Mshamu bin Kombo, who was a relative or possibly, as Tolmacheva claims, Bw. Kitini's brother.
(3) Except for minor, though discernible, differences between the lists of the sultans given by both informants, most versions are consistent to a surprising degree. This seems attributable to the fact that there were only two informants, Kitini and Mshamu, who also were related, and who therefore themselves probably shared the same source(s). Given the differences of detail beyond the kinglists, if one of those earlier sources was a written one, such as an actual “Book of the Kings of Pate,” that source seems to have afforded the informants little beyond names and regnal dates.
