Book excerpt: From medieval maps to digital cartograms, this book features highlights from the Bodleian Library's extraordinary map collection together with rare artefacts and some stunning examples from twenty-first-century map-makers. Each map is accompanied by a narrative revealing the story behind how it came to be made and the significance of what it shows. The chronological arrangement highlights how cartography has evolved over the centuries and how it reflects political and social change. Showcasing a twelfth-century Arabic map of the Mediterranean, highly decorated portolan charts, military maps, trade maps, a Siberian sealskin map, maps of heaven and hell, C.S. Lewis's map of Narnia, J.R.R. Tolkien's cosmology of Middle-earth and Grayson Perry's tapestry map, this book is a treasure-trove of cartographical delights spanning over a thousand years.
