Jamshid is the most well-known of all the kings of the Shahnama (The Book of Kings), the Persian national epic that relates the deeds of the heroes and kings of pre-Islamic Iran. Jamshid taught his subjects many crafts, which made their lives better and more fruitful. As shown in this painting some of the crafts he taught them were how to make arms and armour from iron and how to spin, weave and dye linen, silk and wool to produce clothes.
