From the Holy Mountain is a superb travelogue of Dalrymple’s 1994 journey in the present day Middle East, as he frequents places visited in the late 6th century by the medieval Monk, John Moschos in what was then the Byzantine Empire. Delivering a splendid account of how Christian communities have been impacted over time as Islam has ascended to become the predominant religion, Dalrymple’s story is a reminder of the importance that Christianity used to play in this region and that is in danger of being completely erased from this part of the world.
