Mark Ovenden has made a career of publishing books about transportation systems and their maps that are both comprehensive and copiously illustrated. These include books about transit maps, railway maps and airline maps, as well as books about specific transit systems like the London Underground and the Paris Metro.
His latest, Underground Cities (Frances Lincoln, 22 Sep), is in some ways a natural progression from his past work: in the introduction he muses on the link between transit geekery and wondering about “what else lies down there beyond the walls” (p. 6). But in other ways this is quite a different book.
The March 2020 issue (PDF) of Calafia, the journal of the California Map Society, has as its theme the mapping of space. It also has something from me in it: my review of the third edition of Nick Kanas’s Star Maps: History, Artistry, and Cartography. An excerpt:
It’s important to remember a book’s target audience—its imagined ideal reader. In the case of Star Maps this is Kanas’s younger self, who came to map collecting via his lifelong interest in amateur astronomy. “I was frustrated that there was not a single book on celestial cartography that could inform me about the various aspects of my collecting,” he writes in the preface to the first edition. “What I needed was a book that not only was a primer for the collector but also had sufficient reference detail to allow me to identify and understand my maps. Nothing like this appeared, so I decided to write such a book some day” (p. xxi). In other words, for a compendium this is a surprisingly personal book, one that reflects his own journey into the subject and, presumably, his interests as a collector.
I’ll post the full review on The Map Room once I’ve checked my draft against the published copy. In the meantime, check out the issue of Calafia (PDF) in which it appears. (Update, 24 Jun 2020: Here it is.)
We expect maps to tell the truth; indeed we need them to on a fierce and primal level. “I believe cartography enjoys an enviable position of credibility and confidence among the people who see it. If you see it mapped, you believe,” wrote Charles Blow last fall; he was writing in response to Trump’s petty defacement of a hurricane forecast map with a marker. The reaction to Trump’s stunt, was, I thought, revealing. It’s part and parcel with what Matthew Edney refers to as the ideal of cartography: striving toward a universal, unbiased and perfect map.
Maps have to tell the truth. They simply have to. Maybe that’s why stories about mistakes on the map, and the havoc those mistakes cause, fascinate us so much. Which brings me to three books, all published for the first time in 2016, that talk about map errors of an older kind: islands and other features that appeared on maps, sometimes for centuries, that in the end turned out not to exist.
Matthew H. Edney’s Cartography: The Ideal and Its History (University of Chicago Press, April) is a full-throated jeremiad against the concept of cartography itself—the ideal of cartography, which after 237 densely argued pages Edney says “is quite simply indefensible.” Or as the subtitle to the first chapter states: “There is no such thing as cartography, and this is a book about it.”
On the surface this is a startling argument to make, particularly for Edney, who holds two roles that are very much about cartography and its history: he’s the Osher Professor in the History of Cartography at the University of Southern Maine (where, among other things, he’s affiliated with the Osher Map Library) and the current director of the History of Cartography Project. With this book, Edney is essentially undermining the foundations of his own profession.
Map illustrations. Illustrated maps. Pictorial maps. Map art. There are many different names for a form of mapmaking that is, to appropriate a phrase, “not intended for navigation,” but rather for purposes such as advertising and promotion, political propoganda, decoration, or simply pure art. You may not be able to find your way home with such maps, but that’s not to say they don’t have a purpose.
I’ve reviewed books about maps in this general field before. Stephen J. Hornsby’s Picturing America (reviewed here) explores the rich pictorial map tradition in the United States during the early and mid-20th century. The Art of Map Illustration (reviewed here), on the other hand, is a focused, step-by-step guide to the how of modern-day map illustration.
For the last two and a half years, Betsy and Greg have written a blog of the same name for National Geographic; from 2013 to 2015 they did the same thing with Map Lab, a map blog for Wired. Their background with regard to maps is similar to mine: “We are not experts in cartography or its history; we’re journalists with a lifelong love of maps who were eager to learn more,” they write in the book’s introduction.
Edited by the historian of exploration Huw Lewis-Jones, The Writer’s Map is a collection of essays and maps that explore the relationship between maps and stories; the essays are written both by the creators of those stories—Cressida Cowell, Lev Grossman, Frances Hardinge, David Mitchell and Philip Pullman make appearances—and by the mapmakers who were inspired by those stories, such as Roland Chambers, Daniel Reeve and others. It also draws an important connection between travel and adventure stories of the past and modern fantasy, and explains why “here be dragons” is as much an attractant as it is a warning. Read my review.
Every year, at about this time of year, gorgeous hardcover collections of maps start appearing in bookstores. The timing is not coincidental: map aficionados need gifts bought for them, after all. But there’s something about these books, usually assembled from a single library’s massive collection, that’s worth thinking about. The British Library, for example, has more than four million maps in its vaults—how does an author preparing a book based on that collection decide which of those maps to include? (Some maps will be no-brainers: they cannot not be included.) And less obviously, but more critically, how do you organize the book, if it has no specific theme or focus? If you’re going to put out a book that says, essentially, “look at all these maps we’ve got locked up here,” you have to decide on some kind of order.
There are several ways to do it: Treasures from the Map Room, Debbie Hall’s 2016 collection of maps from the Bodleian Library (reviewed here), organizes itself by subject, for example. Whereas the book under consideration here, Atlas: A World of Maps from the British Library (The British Library, 11 October), curated by the Library’s Tom Harper, organizes its many interesting and beautiful maps by continent. This is exactly the structure of a world atlas, and explains Harper’s choice of title. The chapters on each continent are bookended by chapters on the universe, world maps, seas and oceans, and fantasy worlds; and the continents are deliberately and pointedly arranged in alphabetical order, with Africa leading and Europe last.1
The bare bones of Tharp’s story are therefore fairly well known: while mapping the floor of the Atlantic Ocean, she discovered the presence of the Mid-Atlantic Ridge—and, more specifically, its rift valley, providing tangible evidence of continental drift. Because continental drift was at that point considered to be a crackpot theory, it took some doing for Tharp’s discovery to be accepted; and when it was her contributions were to some extent minimized.
While Felt’s book is positioned as a biography, its strength is in the details of that pivotal discovery: how and where it was made, and by whom, and in what context. Tharp’s work was not done in a vacuum, and how and why she was where she was is important. Felt sets the stage for us: not only does she take us through Tharp’s early childhood and rather variegated education and her arrival in 1948 at the Lamont Observatory, she gives us a short history of that Observatory, of the theory of continental drift, of her colleagues—notably her lifelong collaborator (and possibly life partner) Bruce Heezen and Observatory director (and sometime antagonist) Maurice Ewing. More than anything else, Soundings provides context for Tharp’s discovery: by the time we’re done, we know how important it was, and why. We’ve been well briefed.
Felt is less successful in building a portrait of Tharp herself. Some areas of her non-work life—her childhood, family and college education, for example—are extremely well covered, but other areas have considerable gaps, particularly those involving her personal life. The nature of Tharp’s relationship with Heezen is only hinted at, as is an early, unsuccessful marriage to someone else. Her later life, supported by a motley gang of eccentrics called Tharpophiles, is also incompletely covered. The elisions, however unintended, are frustrating. I suspect the author was a prisoner of her source material, which in places she follows very closely; I would have liked it if more had been done to fill in the gaps.
Soundings was published in hardcover by Henry Holt in 2012. It’s available in paperback and ebook from Picador.
It’s become a commonplace that modern technology has eroded our ability to navigate: that relying on GPS and smartphones is destroying our brains’ abilities to form cognitive maps and that we’d be utterly lost without them.1 I’m not sure I subscribe to that point of view: plenty of people have been getting themselves lost for generations; relying on an iPhone to get home is not much different from nervously having to follow someone’s scribbled directions without really knowing where you’re going.
For my part, I can’t get lost. That doesn’t mean it’s impossible for me to get lost: that has, in fact, been known to happen. I mean that I can’t allow myself not to know where I am under any circumstances. I’ve got a pretty good cognitive map, but if I’m in a strange city without a map of said city, I’m deeply uncomfortable if not upset; provide me with a map to get my bearings with and I’m immediately at ease. In my case, having an iPhone—with multiple map applications—means I don’t have to get to the nearest map outlet as soon as freaking possible. It’s not, in other words, an either-or situation.
John Edward Huth is firmly in the former camp. He’s a particle physicist at Harvard who’s worked on the Higgs boson who for years has been running an interesting side gig: he teaches a course on what he has called “primitive navigation”—the ancient means of navigating the world that existed prior to the advent of some later technology. The course, and the accompanying book, The Lost Art of Finding Our Way (Belknap/Harvard University Press, 2013), are an exercise in recapturing those methods.
Mark Monmonier’s How to Lie with Maps has always been about how to read maps, not how to make them. The map-using public is inclined not only to believe what’s on the map, but to trust it: why would so many people willingly drive their cars into ditches, if they didn’t trust their cars’ navigation systems more than their own eyes? Monmonier prescribes “a healthy skepticism” about maps, and this book is a tool to that end: “I want to make readers aware that maps, like speeches and paintings, are authored collections of information and are also subject to distortions arising from ignorance, greed, ideological blindness, or malice.”1 The book is essentially a cheat sheet, showing all the ways that maps can be made to shade, or at the very least, select the truth. At the minimum, mapmakers must decide what to include or exclude, and those decisions may not necessarily be honest or fair.
The first edition of How to Lie with Maps came out in 1991, the second in 1996. (See my review of the second edition here.) Since then the cartographic landscape is much changed: the map a person may use most frequently may come via their phone rather than paper. But the advice found in this book is still valid. What goes for a paper map is still relevant to the map you call up on your iPhone. And so now, 22 years later, we have a third edition of How to Lie with Maps, which came out from the University of Chicago Press last April. For the most part it’s familiar territory. Other than a nip and tuck here and there and a few new chapters at the end, it’s largely the same book it was in 1996. How does it measure up in the present moment?
Mostly well, with some caveats. The core message of How to Lie with Maps will not become obsolete until maps do, which is to say never; but the examples and emphases are starting to become a bit dated. The reader might have to do a little more work in some cases to see the applicability of a chapter—to translate it into familiar terms—but that effort will be rewarded. For example, I think that everyone working with web-based maps should become quite familiar with chapter 3, “Map Generalization,” for its insights on what to include and exclude at different scales. The chapter on data maps, discussing the use of choropleths, cartograms and other data visualizations, is absolutely essential: so many of the maps being circulated as memes are data maps of some kind, and anything that improves the critical eye with regard to such maps is going to help.
But that chapter on data maps does get a bit lost in the weeds, especially for the general reader. And I’d have liked to have seen something on heat maps akin to this xkcd cartoon:
Bad internet maps have been described as a “social media plague”: they’re popular, they’re insidious, and they’re often not even wrong. But they’re not specifically dealt with in How to Lie with Maps, and that’s a blind spot: in the era of fake news, hoaxes and state-sponsored mendacity, maps that go viral are the ones most in need of a vaccination campaign.
Instead, the new chapters focus on image maps (satellite and aerial imagery), prohibitive cartography (which seems out of place here, and seems more a summary of Monmonier’s other work) and “fast maps,” which is more about web-based mapping than the stuff that gets shared on social media. The new chapters are noticeably more concise than the old. The net effect is a book that is still important, still relevant and still badly needed, but whose updates don’t quite bring it up to the present.
What do we mean by mapmaking? That’s a less straightforward question than it appears at first glance. A cartographer might talk about projections, scale, use of symbols, deciding which information to put on the map; a digital mapmaker might emphasize GIS and data layers and data sources. Your assumptions about what mapmaking is depends largely on the maps your yourself make. And what we mean by “map” can be quite different depending on the context.
There are some illustrations that are a great help in understanding concepts and tools whose use is not immediately obvious, but, as the subtitle suggests, this is not a book that goes into much depth. At only 144 pages—20 percent of which is taken up by front matter, glossary and index—it can only give the barest of introductions to the subject. That can be maddening for the reader, particularly when its coverage is so uneven: there’s a fair bit on the tools and techniques used during the age of sail, but only a paragraph on LORAN and Loran-C, for example. Another frustration is Bennett’s extremely discursive style, as though he were giving a posh invited lecture; I kept feeling that more could have been included had his prose been tightened up.
All the same, there’s value in a book that styles itself, modestly, as an introduction. An introduction is where you begin. It’s the first step, not the finish line. It sets out the parameters of the field and gives you just enough to know what’s out there. For someone like me, it tells me where the gaps are in my knowledge. To paraphrase someone, it lets you know what you do not know. It tells you where to go next: the most useful part of the book may well be its “Further Reading” section; you just need the preceding 116 pages of text to know how to use it.
And for all my concerns about brevity and prose, it’s a good deal more accessible, and easier to read, than the equivalent Wikipedia page—and it went through an editorial process, too. And while it’s not free, it’s very modestly priced. So I have no regrets about buying it.
