To categorise this as a travel book is misleading. In fact it is anthropology and history with two main settings: rural Egypt in relatively modern times and a web of commercial and cultural interactions from the Mediterranean to the western coast of India uncovered by a medieval Jewish manuscript found amongst the detritus of an old synagogue in Cairo. It's an account of social change, of the loss of a cosmopolitan and even peaceful way of transacting things across seas and cultures to an alien brutality, the bellicose European way of doing things, and the resultant foreclosure of mutual understanding, as exhibited in small Egyptian communities whose interpretation of the world has thereby become so different. Greatly evocative, incredibly researched, a wonderful read.
