This is the first English translation of the last known philosophical work of the great eleventh-century Ismaili thinker, poet, and Fatimid emissary, Nasir-i Khusraw. Appointed from Cairo by command of the Fatimid Imam-caliph al-Mustansir to serve first as a daʿi, and then as the hujjat, for the entire region of Khurasan, he maintained his allegiance to both his mission and his Imam for the rest of his life, even when threatened and driven into exile.
