Jones's text, too, is precise but calm, elegant and with a certain charm. His learning is broad: here's Ptolemy, here are gear ratios, here's Cicero and Galen, Babylonians, planets, lunar months, Glauco, epicyclics and the 'Spindle of Necessity'. And it is not just the cosmos that is demonstrated, but the vast difference, and astonishing similarity, between us and our ancestors. ... Read moreSo out of the history of science comes a sense of our humanity and the ancient desire to comprehend. God knows, it's timely, in the shrivelled cosmos we are building. We need more books like this. And probably more sponge-divers, too.
Michael Bywater, The Spectator
A Portable Cosmos is set to become the definitive history of the Antikythera Mechanism, and will be of great value to specialists, as well as students and those interested in ancient Greco-Roman science and technology.
Liba Taub, University of Cambridge
A nimble, comprehensive survey of a wondrous machine
Barbara Kiser, Nature
His virtue as an author is an exhaustive knowledge of his subject ... refreshingly candid
John J. Miller, Wall Street Journal Europe
Jones' book is written in such a way that makes it profitable reading for a wide range of readers, from the specialists on the Mechanism to those who have never heard of it.
Efthymios Nicolaidis, Almagest
Jones takes the reader on a journey through the various years of research into the mechanism's background, as well as into the device itself, awarding a glimpse beneath the corroded surface and into the interior gears and cogs.
Jade Fell, Engineering and Technology
As riveting as any thriller or criminal investigation... Jones's text... is precise but calm, elegant and with a certain charm... We need more books like this.
Michael Bywater, Spectator
Convincing.
Andrew Robinson, History Today
[Jones] provides just enough general context for readers to understand the astronomical background, while being just technical enough for them to feel that they have a grasp of the object's complexity.
Serafina Cuomo, London Review of Books
This is a remarkable book about a remarkable device. After reading A Portable Cosmos, the Antikythera Mechanism seems a little less different and strange, a little less impossible but no less of an ancient wonder. In clear and lucid prose, Alexander Jones has successfully integrated all the necessary literary, archaeological, and forensic evidence relevant to the Mechanism. The result is a detailed, thorough, and perceptive analysis which will surely stand as the definitive handbook on the Antikythera Mechanism for some time to come.
Alex Nice, Bryn Mawr Classical Review
Jones has, in short, produced a superb guide to this dazzling embodiment of ancient astronomical knowledge and mechanical technology. Detailed enough that even scholars of ancient science will learn much, yet readable enough that undergraduate students will find it approachable (I myself have tested out both audiences), this book ends the long wait for a thorough, reliable, and accessible guide to the Antikythera Mechanism.
Courtney Roby, Cornell University, in Classical World
[Jones] presents a very readable account of the Mechanism, and the consensus of what it was used for... [An] excellent 'User Manual'.
Journal of the British Astronomical Association
This book will be invaluable to those engaged in the study of the science of the ancient Greeks and Romans. Endnotes and references will assist individuals who wish to delve into further research. The presented black-and-white photographs and drawings are essential to understanding the work's subject matter. ... Summing Up: Recommended. Graduate students, faculty, and professionals.
M. Dickinson, CHOICE
The book is a triumph at several levels, as an account of high-grade detective work, as an exposition of ancient astronomical ideas, and as a disquisition on where those ideas fitted into the society that produced them. ... This is recommended reading for anyone interested in ancient astronomy.
