Medieval Islam Islamic cultures are among the most interesting, complex, and dynamic in the world. At the same time, they are among the least known in the West. From its dramatic rise in the seventh century A. D. to the present, Islamic civilization has covered a large part of the globe, incorporating many subcultures and languages into its orbit, and vigorously engaging the peoples around it.

Responding to circumstances of time and place, Islamic physicians and scholars developed a large and complex medical literature exploring and synthesizing the theory and practice of medicine.
