Jami' al-tawarikh
The lavish illustrations and calligraphy required the efforts of hundreds of scribes and artists, with the intent that two new copies (one in Persian, and one in Arabic) would be created each year and distributed to schools and cities around the Ilkhanate, in the Middle East, Central Asia, Anatolia, and the Indian subcontinent. Approximately 20 illustrated copies were made of the work during Rashid al-Din's lifetime, but only a few portions remain, and the complete text has not survived. The oldest known copy is an Arabic version, of which half has been lost, but one set of pages is currently in the Khalili Collection, comprising 59 folios from the second volume of the work. Another set of pages, with 151 folios from the same volume, is owned by the Edinburgh University Library. Two Persian copies from the first generation of manuscripts survive in the Topkapı Palace Library in Istanbul. The early illustrated manuscripts together represent "one of the most important surviving examples of Ilkhanid art in any medium", and are the largest surviving body of early examples of the Persian miniature.
Calligraphy
On the subject of Indian calligraphy, writes:
Aśoka's edicts (c. 265–238 BC) were committed to stone. These inscriptions are stiff and angular in form. Following the Aśoka style of Indic writing, two new calligraphic types appear: Kharoṣṭī and Brāhmī. Kharoṣṭī was used in the northwestern regions of India from the 3rd century BC to the 4th century of the Christian Era, and it was used in Central Asia until the 8th century.
In many parts of ancient India, the inscriptions were carried out in smoke-treated palm leaves. This tradition dates back to over two thousand years. Even after the Indian languages were put on paper in the 13th century, palm leaves where considered a preferred medium of writing owing to its longevity (nearly 400 years) compared to paper. Both sides of the leaves were used for writing. Long rectangular strips were gathered on top of one another, holes were drilled through all the leaves, and the book was held together by string. Books of this manufacture were common to Southeast Asia. The palm leaf was an excellent surface for penwriting, making possible the delicate lettering used in many of the scripts of southern Asia.
