The student of Persian painting normally approaches manuscripts of Qazwīnī's “Marvels of Creation” (‘Ajā’ib al-Makhlūqāt) with a certain wary apprehension. Copies of the work generally contain a very large number of miniatures, and thus tend to suffer, like some manuscripts of the Shāhnāma, from “painter's fatigue”—in other words the standard of painting deteriorates as the manuscript proceeds, as if the artist, who may have started off with a fine flourish, found himself, after the first hundred or so miniatures, physically wilting and mentally inert. This is, of course, only human, considering that he was required to produce small and stereotyped illustrations of an interminable series of angels, constellations, beasts, birds, insects, trees, and plants. But it means that copies of the “Marvels of Creation” of first-rate quality are exceedingly rare. The present manuscript, though not in the top flight, may be assigned a very respectable place in the second rank, and has in addition one or two other characteristics that make it a more interesting subject of study than the majority of Qazwīnī manuscripts.
