Alongside the famous characters who coloured this landscape, including Muhammad's controversial cousin, 'Ali; the first Sultan of Egypt, Saladin; and the poet Rumi, the reader will also meet less wellknown figures, such as Shajar al-Durr, slave-turned-Sultana of Egypt, and Ibn Fadlan, whose travels in Eurasia brought first-hand accounts of the Volka Vikings to the Abbasid Caliph.
