This book attempts quite a bold brief: 'Global Events at a Glance'. And in many ways it achieves that goal quite effectively. Essentially a combination of pages of illustrated timelines interleaved with the 54 global maps positioned chronologically within the text, the book makes an interesting browse. The maps show types of human subsistence, technological development, migrations, trade patterns, empires and dominions, religious and political affiliations, alliances etc and flicking through one can easily see the ebb and flow of political power and other elements in human cultures. The running world population graph at the bottom of selected timeline pages is fascinating (estimated population falling significantly post Black Death ravages, for example) and biggest 5 cities chart which accompanies each of the maps immediately illustrates our Euro, and then western-centric attitudes. Eastern cities which I often haven't heard of dominate for centuries. There are also two pages of reference maps at the end showing key cities and with 5 inset enlarged views. There is an A-Z of Peoples and Nations and substantial index.
The timelines are divided into 4 bands: Politics and Economy; Religion and Philosophy; Science and Technology; Arts and Architecture: these seem to be colour-coded to link with the map which precedes the timeline. There is a mass of information: for example, in Religion and Philosophy between 1600 and 1610 I can quickly see significant events occured in China, Japan, the Mughal empire and Macassar, though I struggle to see where Macassar is shown on the map, or how the colour used ties in with the information, unless the colour is decorative, in which case it is really confusing. The information, more particularly any related image, is not always clearly positioned on the these pages: it took me some time to find the confirmation that what I presumed was Stonehenge actually IS Stonehenge on pp28-9.
Clarity is, I would suggest, the central problem with this book. The colour key used to delineate the various features each map might be focusing on is not always sufficiently differentiated to be clear. The same is true of the attempts to itemise smaller areas by using coloured and numbered shield-like shapes: the keys for these are not uniformly positioned and can be clumsy to access. The author has decided, for good reason, to use global maps only, but that can lead to a specific region in a specific era when a lot was happening, seeming to be very jumbled and squeezed. Perhaps the European scramble for African colonies, say, deserved a bigger, more focused map, though at a loss of other advantages. I also feel that at least once, there should be a global map which shows a more realistic representation of the various land masses. The UK is as big as Spain throughout in this projection used: that's necessary for clarity of information, but just once let's be shown how it really is.
The book is beautifully produced, as one would expect from Thames and Hudson, but I'm not at all sure how useful I would find this as a reference tool. If I wanted to know about the Sumerians, would this tell me much that I couldn't access in greater detail quite easily elsewhere? Probably not. But the purpose of this book, I suppose is to map the flux of civilisation(s) over time, and this book certainly gives a vivid sense of that process and makes for a very interesting browse. What it might well do is prompt taking insights further by doing other research elsewhere, and it is perhaps unreasonable to expect too much more of a book with the ambitions this has within the constraints of size and cost.
