The Shahnamah (RAS 239) copied for the Timurid prince, Muhammad Juki (1402–1445) in Herat, has long been considered one of the finest surviving, illustrated Timurid manuscripts. It was presented to the RAS in 1834 by Lieutenant Colonel Doyle (1787–1848), but attracted little scholarly attention until Barbara Brend published her monograph in 2010. The manuscript contains 31 exquisite miniature paintings, two of which (fol. 430v and fol. 531r) were added later during the Mughal period (1526–1761). This article will examine the sumptuous, jewel-like colours employed to depict scenes from the epic and the metals, pigments, and dyes from which they were derived. Precious metals and organic colours made from plants such as indigo and lac extracted from female insects are examined in detail: the methods of their production and extraction, the techniques used for their application, their commercial value, and the prestige they afforded their patrons all contribute to an understanding of what constituted the miniature painters' palette in the Timurid period.
