Flattening the Medieval Earth explores the origin of the ‘flat error’, i.e. the false accusation that ancient and medieval Christians believed in a flat Earth, and what this implies in terms of a conflict between science and Christianity. Engaging with scientific and religious debates, this book includes a reception study of two key figures of the 4 th century AD, Lactantius and Augustine.... Read more

“Flattening the Medieval Earth is an important study of two historical transformations: of terrestrial geography in Columbus’s wake and of its later weaponisation in anti-religious rhetoric. Pablo de Felipe writes an engaging biography of a pervasive error –the belief that medieval Christendom had been flat-Earthbound.”

- John Hedley Brooke, Oxford University, UK

 

Flattening the Medieval Earth is brilliant interdisciplinary research on how, in the 16th-17th centuries, several factors (including defending Copernicanism) led to the wrong idea of a medieval flat Earth, contributing to the prejudice of a permanent conflict between science and Christianity.”

- Miguel Á. Granada, University of Barcelona, Spain

 

Flattening the Medieval Earth is a kaleidoscopic revelation of the richness of medieval discussions about the Earth’s shape and population. With masterful command of the sources and keen analytical eye, Pablo de Felipe clarifies the origin of the Flat Error and much more.”

- Henrique Leitão, University of Lisbon, Portugal

 

“Flattening the Medieval Earth is a ground-breaking study of the medieval debate around the shape of the Earth and the Antipodes. Pablo de Felipe convincingly demonstrates that it arose from within Christianity and not from a dichotomy between ‘science and faith’.”

- Karla Pollmann, University of Tübingen, Germany

Flattening the Medieval Earth contains a wealth of information from a rich range of sources, many translated by de Felipe himself. It demonstrates pretty definitively that in the period of which he writes there were many voices raised on the subject of the shape of the Earth, and that these waxed and waned in the influence they exerted. The central argument of the book – that the medievals did indeed think that the Earth is spherical, but that the fiction that they did not can be traced to an earlier point in history than has hitherto been acknowledged – is persuasively made. […] This book is a valuable addition to the scholarship around a particularly fascinating historical episode, and I’m sure it will be very influential in the future of that scholarship for some time to come.”
