Measure of Multitude - Biller, Peter (Professor of History, Professor of History, University of York)

Peter Biller's innovative study challenges the view that medieval thought was fundamentally abstract. He describes what medieval people 'thought' about population, studying the texts which constrained their thought, and examining the medieval realities which shaped it, such as birth, birth-control, sex-ratio, marriage ages, length of life, and the population of the Holy Land.
