This novel takes as its subject one of Arab and Islamic history’s most perplexing figures, al-Hakim bi-Amr Illah (“the ruler by order of God”), the Fatimid caliph who ruled Egypt during the tenth century and whose career was a direct reflection of both the tensions within the Islamic dominions as a whole and of the conflicts within his own mind. In this remarkable novel Bensalem Himmich explores these tensions and conflicts and their disastrous consequences.
