Michael Rand’s The Evolution of al-Ḥarizi’s Taḥkemoni investigates the stages whereby the text of al-Ḥarizi’s maqama collection as we currently know it, on the basis of manuscripts (and the editio princeps), came into being during al-Ḥarizi’s travels in the East over the course of approximately the last ten years of his life. The discussion is based on a close examination of the textual evidence, the investigation of a number of relevant literary motifs, and a comparison to al-Ḥarizi’s model, the Maqāmāt of al-Ḥarīrī. The book includes a catalogue of fragments of the Taḥkemoni in the Genizah and Firkovitch IIA collections, and some previously unpublished material that can reasonably be claimed to belong to a heretofore unattested version of the Taḥkemoni.
