If you wish to thoroughly accustom yourself to correct and good positions for your fingers, fasten a frame or a loom divided into squares by threads between your eye and the nude figure which you are representing, and then make the same squares upon the paper where you wish to draw the said nude but very faintly. You should then put a pellet of wax on a part of the network to serve as a mark which as you look at your model should always cover the pit of the throat, or if he should have turned his back make it cover one of the vertebrae of the neck. ...The squares you draw may be as much smaller than those of the network in proportion as you wish your figure to be less than life size...

In the Seljuk period, figurative themes of Turco-Mongol character are some what apparent in all the minor arts in both Iran and Iraq. The true Persian miniature, however, which is indisputably the most perfect figurative art on the soil of Islam, did not come into the world until after the conquest of Iran by the Mongols, and more precisely under the rule of the Īl-Khāns (1256). It is modeled upon Chinese painting with its perfect blend of calligraphy and illustration...The link between writing and image remains fundamental to Persian miniatures, which, belongs, as a whole, to the art of books; all the famous miniaturists were calligraphers before becoming painters.
