The Fourth Part of the World: An Astonishing Epic of Global Discovery, Imperial Ambition, and the Birth of America [Paperback]

Simon Winchester's review above does not give this book justice, although I must say that Lester's ability to spin a great story around an arcane subject may rival Winchester's. To me this book is about so much more than the naming of America on a map - it is really about the process of discovery and enlightenment and the pitfalls and pratfalls along the way. I ordered the book in an attempt to research an even more arcane issue I did not find in the book, but was immediately captivated by the exposition, and set my current book aside to read this to completion.

The title of the book could maybe not be more cryptic or off-putting, but don't let that deter you. The Fourth Part of the World refers to the somewhat mythical, yet actual undiscovered lands (after Asia, Europe and Africa) described by the ancients which we know now as America. Lester spins an exhaustively researched yet page-turning story of how this mythical land was gradually given substance and shape by explorers and cartographers. That the mapmakers at the center of the story write "America" on their map is almost incidental to the story. The great story, which Lester tells so wonderfully well, is how incredibly important world maps effected the philosophy of the day. Lester makes the case that it was this map that caused Copernicus to form his theory of the Universe, which if true, is far more significant than simply naming America.

For the average reader like me, this book will fill in a lot of the gaps in your learning about the age of exploration, and possibly give insight to the shortfalls and missteps we continue to repeat while exploring new domains without the proper "map".

"The Fourth Part of the World" is truly not an arcane subject, and it's a wonderful read.

A six-star book, and one of my favorite book discoveries of the year. This is the kind of book that makes me wish that Amazon allowed us to award an extra bonus star to truly outstanding works.

Remember all those hours we all spent in classrooms, at least one of which had a world map spread out across one wall, and how familiar that world came to look to us, with the Atlantic separating the Americas from the vast landmass of Europe and Asia, and Africa extending south between the Atlantic and Indian oceans? Well, in this fascinating and lively history, Toby Lester tells us how -- over the course of many centuries -- that map and the shape of the world it presents came to be understood and accepted, and how slowly and painfully that process was. Even more intriguing, it's the story of how a world view evolved over even more centuries; of how Europeans who once saw themselves as inhabiting a tiny island surrounding by vast amounts of ocean, with Jerusalem -- as their holy city -- at its center, came to understand the implications of voyages of discovery on foot, horseback and eventually by sea for their view of geographical reality.

Travelers began to venture from Europe into unknown lands centuries before the map at the heart of this book that first identified America as a separate continent and named it after Amerigo Vespucci was first printed in eastern France in 1507. Those who came back -- Papal envoys from the Mongol court, Marco Polo from China and the East Indies -- had wondrous tales to spin -- but where, exactly, was it that they had been? Mapmakers scrambled to keep up. Sometimes the works of these early geographers owe more to invention than to what we now know to be true; sometimes they were able to make big leaps forward after significant voyages of discovery such as those of the Portuguese explorers down the African coast, or of the rediscovery of ancient geographical tomes, such as Petrarch's copy of the earliest Latin geographical work ever found by Pomponious Mela.

We may all know the story of Columbus and other 15th and early 16th century explorers and their voyages, but what I found fascinating to read about were those that had taken place centuries earlier, such as voyages by Italian mariners commissioned by the Portuguese king in the mid-1300s to set off in search of some islands believed to exist somewhere in the Atlantic. They ended up discovering the Canary Islands (as they are now known today) and proceeded to pillage, loot and take prisoners home with them in hopes of converting them to Christianity. (Setting a pattern that would repeat itself on a vaster scale centuries later, as Lester points out.)

In the world we live in today, where there are no significant undiscovered lands and few major geographical puzzles left to solve, this book is particularly enticing. It put me squarely back in the minds of these medieval and Renaissance travelers, scholars and mapmakers as they struggled to put together a jigsaw puzzle to which half the pieces were still missing, and produce an accurate view of the world they were still discovering. Following in their footsteps was exhilarating, thanks both to the facts themselves and to Lester's extremely knowledgeable but always lively writing. While Lester does great work in making the process of map-making itself understandable, he doesn't shun the livelier bits and pieces of the story, such as the way "Mongol chic" spread through western Europe the late 13th and early 14th centuries. (Italian parents even named their sons after Mongol khans!)

This book was sheer delight to read, as it combines intellectual history (the story of the transmission of knowledge and of how new discoveries were incorporated into and transformed the way people viewed their world), science (the art of navigation and marine map-making, for instance) and the stories of the explorers, both those whose curiosity could be pursued only from the medieveal version of an armchair as well as those like Columbus and Vespucci who took the helm of their ships and sailed off into the unknown. (I confess I particularly enjoyed the attention given to some of the more obscure figures, from the mapmakers who finally produced the map bearing the label 'America' to early 14th century Papal scholar Poggio Bracciolini, long a favorite historical character of mine for his intrepid book-hunting expeditions.)

This is a story that may owe its existence to a map but which stretches far beyond that, to tell the story of how we learned to learn about and think about the world we inhabit. It's an ambitious book, but one that will promptly be added to my "top 100" books; the volumes I don't ever want to be without. It will appeal most readily to those with an interest in history and exploration, but I defy anyone to read it and not immediately set off in search of more reading on the topic. (For anyone who hasn't already read it, Daniel Boorstin's The Discoverers is a good overview book, although it doesn't pack the same kind of wallop as this one.) On a bit of a tangent, if you enjoyed this, you might find Island of Lost Maps, (True Story) by Miles Harvey to be intriguing, as it's the tale of how much today's collectors cherish some of these very early maps and the crimes they will commit to possess them.

Highly, highly recommended. If I could put it more strongly than that, I would.

This is my favorite book of the year. I am giving it to friends and family for Christmas. It is the story of the map that named America -- a remarkable map that is now the central feature in the lobby of the Library of Congress in Washington. But, told engagingly by Toby Lester, it is also a story of intrigue, deception, sex, and bribery -- the story of competition among early explorers and their patrons to find and document ( and mis-document) new worlds. A remarkable achievement.
