Heaven and earth in the Middle Ages

In this fascinating book Dr Simek shows that though nature was thought to be permeated by the will of God, there were numerous explanations for unknown phenomena, from the simple theories of the early middle ages to the more sophisticated ideas of the centres of learned scholasticism in Paris and Oxford. He presents a cross-section of the medieval knowledge of the physical world as deliberated and discussed by authors from the 9th to the 15th centuries.
