“Author of numerous books, book chapters, and articles on related topics, Wright has deep mastery of all the major treatises written in the centuries both before and after Ibn Kurr’s treatise (in Arabic, Persian, and Turkish).” - Scott Marcus, University of California, Santa Barbara “This edition has been fastidiously prepared. The Philology is near impeccable. Wright has done a superb job of deciphering a codex that demands considerable guesswork (words without dots).” – Li Guo, University of Notre Dame
