The oldest is the Köprülü copy in Turkey, written fourteen years after the author’s death; upon it the text was primarily established, and we departed from it only when a clear error or an omission that distorted the wording was evident.
The Paris copy (B) agrees with the archetype in many places, as does the Jerusalem copy (Q); it is therefore likely that these manuscripts derive from a single exemplar.
I have recorded the variant readings of the other manuscripts in the footnotes, together with any additions unique to them, unless the text required their inclusion, as stated earlier. The copies labeled (F) and (K) usually concur, although the points where they differ indicate that (K) was not copied from (F).
