This l:ittıe book consists of the publication and evaluation of a single rpa]or text, namely the foundation document of Koca Sinan Paşa's mosque, imaret and han comlex in Uzuncaova, probably written about 1593. Apart from a biögraphical introduction on Sinan Paşa, the volume contains a detailed description of the document in question, which, as many valcfiyes of this period, was written in Arabic. A discussion of the revenues assigned to the foudation, and a listing of the uses to which the responsible administrators were expected to put these funds, make the text accessible to the user who does not read Arabic. A separate seetion lists all presentıy known copies of the document in question. None of the surviving three copies, one in the Staatsbibliothek Preussischer Kulturbesitz {West Berlin) and two in the Topkapı Sarayı {İstanbul), can be regarded as the origini:ı.l. Rather, all three texts are of the same character, namely certified copies providing fairly little evidence concerning the textual relationship between them, As a result, the authors have preferred to suggest two different stemmas one with a single original, another with two slightıy variant originals. Until further copies are found, it seems impossible to chöose between the two explanations.
