God's Philosophers : How the Medieval world laid the foundations of modern science

God's Philosophers: How the Medieval World Laid the Foundations of Modern Science is a book by James Hannam which rebuts "the idea ‘that there was no science worth mentioning in the Middle Ages … [and] that the Church held back what meagre advances were made’." Hannam argues that "medieval scholars overturned the false wisdom of ancient Greece to lay the foundations of modern science." The book rebuts a number of modern canards about Medieval Christianity, such as:

The idea that the pope tried to suppress the number zero or stop doctors from learning about anatomy through dissection of human corpses
The idea that people in Medieval Europe thought the earth was flat

He lists 13th century inventions such as spectacles, the mechanical clock, and the windmill.
