Decoding the Heavens: A 2,000-Year-Old Computer and the Century-Long Search to Discover Its Secrets
The bronze fragments of an ancient Greek device have puzzled scholars for more than a century after they were recovered from the bottom of the Mediterranean Sea, where they had lain since about 80 BC. Now, using advanced imaging technology, scientists have solved the mystery of its intricate workings. Unmatched in complexity for a thousand years, the mechanism functioned as the world's first analog computer, calculating the movements of the sun, moon, and planets through the zodiac. In Decoding the Heavens , Jo Marchant details for the first time the hundred-year quest to decode this ancient computer. Along the way she unearths a diverse cast of remarkable characters—ranging from Archimedes to Jacques Cousteau—and explores the deep roots of modern technology, not only in ancient Greece, but in the Islamic world and medieval Europe. At its heart, this is an epic adventure story, a book that challenges our assumptions about technology development through the ages while giving us fresh insights into history itself.

Jo Marchant reveals her ease with translating scientific speak into real-life adventure that drives readers of all kinds right to the very end of this fantastic book. Although it took me a while to get into it as a result of my own distraction, once there I found myself wrapped up in the same obsession with the Antikythera mechanism as ruled the lives of these men and women for generations.
Marchant broke down complex realities and interwove the relationships of the scientists involved at every level of revelation to help us all fall in love with this ancient mystery that still holds its own undiscovered origin and purpose.
This may be one of the best non-fiction books on ancient mysteries I have come across. Ever.

decoding the heavens recounts the discovery of the antikythera mechanism, arguably the most remarkable archaeological find in human history. a mechanical computer dating from the second century bce, it was recovered from an ancient mediterranean shipwreck by greek sponge divers in 1900 (after nearly 2,000 years of submersion). its function, however, would elude academics, researchers, computer scientists, and archaeologists for still another century.
an intricate, sophisticated device constructed from dozens of gears, its mechanical complexity is baffling, as similar technology was not thought to have originated until some millennium and a half later.
despite having unlocked the antikythera's inner workings, scholars disagree on its origins, designer, and ultimate purpose. many theories point to hipparchus, ancient greek astronomer & mathematician, as the device's inventor, yet some evidence points instead to archimedes, and others to posidonius, a stoic philosopher. the most recent research seems to indicate that the device's astronomical and technical features may have been based upon babylonian scientific advances. although research remains ongoing, the antikythera's purpose may never be fully discerned. speculation about its application ranges from its possible use in developing horoscopes to a "philosophical or religious demonstration of the workings of the heavens." some even surmise that this ingenious mechanism may not be the only one of its kind.
science journalist jo marchant's engrossing narrative is obviously well-researched. as her book chronicles the technological advances employed in the ever-evolving hunt for answers, we are introduced to an array of frustrated (and betrayed) researchers each racing to be the first to unravel the device's mysteries and collect accolades for their success. for whatever decoding the heavens may lack in style or flourish, it makes up for with intrigue and wonder. that the antikythera mechanism was ever chanced upon and pulled from the sea is itself quite an unlikely feat. that it was ever conceived of and constructed in the first place seems nearly an impossible one.
"its discovery... was as spectacular as if the opening of tutankhamen's tomb had revealed the decayed but recognisable parts of an internal combustion engine." ~derek de solla price (scientist and early antikythera researcher)
whoever turned the handle on the side of its wooden case became master of the cosmos, winding forwards or backwards to see everything about the sky at any chosen moment. pointers on the front showed the changing positions of the sun, moon and planets in the zodiac, the date, as well as the phase of the moon, while spiral dials on the back showed the month and year according to a combined lunar-solar calendar, and the timing of eclipses. inscribed text around the front dial revealed which star constellations were rising and setting at each moment, while the writing on the back gave details of the characteristics and location of the predicted eclipses. the mechanism's owner could zoom in on any nearby day- today, tomorrow, last tuesday- or he could travel far across distant centuries.
an intricate, sophisticated device constructed from dozens of gears, its mechanical complexity is baffling, as similar technology was not thought to have originated until some millennium and a half later.
it's hard to overestimate the uniqueness of the find. before the antikythera mechanism, not one single gearwheel had ever been found from antiquity, nor indeed any example of an accurate pointer or scale. apart from the antikythera mechanism, they still haven't.

I’ve been wanting to read this book for absolute ages! I finally got around to it and must say it did not disappoint.
It’s really hard to find a comprehensive and complete history of the Antikythera mechanism and the many theories surrounding it. And this was put together in such an easy to understand way for someone without any former knowledge on the subject.
Even with the book being dense in knowledge, I did not feel weighed down by it or felt slowed down by the story, it kept great pace and engagement the entire time.
I really enjoyed this book and look forward to obtaining my own copy to add to my library.
5 stars.

This account of the scientific inquiries into a piece of ancient machinery dated to 60-70 BC reads a bit like a Dan Brown novel -- but the story is non-fiction. Drama builds right up to the end, when the magazine Nature published the results of the Antikythera Research Project in November, 2006.
Successive teams of competing researchers have added to knowledge of one of the first known astronomical computers:
* Originally recovered from a wreck off Antikythera Island in 1900, Derek J. de Solla Price originally speculated in the 1950s that it was used to track the motions of the moon and stars. Price was able to show that gearing matched the Metonic cycle used by Egyptian sky calendars.
* Michael Wright would pick up on Price's work and show that the Antikythera mechanism was more complicated, showing the 76-year Callipic cycle, and likely showing the phases of the moon.
* Mike Edmunds, Tony Freeth and others would image the device in more detail -- and find other remnant gears -- while engaged in the Antikythera Mechanism Research Project, who would author the Nature article. They expanded on the complexity again, indicating that the zodiac, sun, moon and even eclipses could be predicted using the Antikythera mechanism.
Along the way there are stories of the jealousy and competition of scientists trying to unravel the origin and use of this device. Its importance to scientific history cannot be underestimated: it may even indicate that the Greek use of the concept of "zero" occurred earlier than Ptolemy, who's given credit for it in the 2nd Century AD.

This is a truly fun exploration about the discovery and research into the Antikythera mechanism. The author does a great job of contextualizing what it is and why it is important while exploring the lives of the people -- mostly, but not all, men -- who researched it over 100 years. The book is entirely approachable and engaging. It makes for a great book to parallel-read with someone and discuss it along the way (my husband and I did this).
The book includes some photographs which, in the hardback are presumably all in the middle of the book (in publishing called the "insert"). Despite being in the middle they actually cover events that happen throughput the book. You'll want to jump past them to avoid spoilers for what's revealed in the second half of the book and come back to them at the end. In the Kindle version they get shoved just after the start of Chapter 6.

Overall Decoding the Heavens is a very well-written and interesting book that often read as smoothly as a fictional tale. The history of the Antikythera Mechanism and the people who became obsessed with it was very interesting. I envy the enthusiasm these individuals showed towards the mechanism but overall I would say it rather negatively impacted their lives. Everything in moderation and such. I also was intrigued by the incorporation of information on diving and the history of archaeological findings at sea. The importance of translations of knowledge through the ages and the different stages of technology in the world since ancient times was quite frustrating to read. It is a bit disturbing to realize how much more advanced society could be with such a simple change in history (the knowledge to create a mechanism like this surviving downfalls of societies). Although, dare I say we could long be gone considering the tragic elements of advancement (climate change, threat of nuclear winter etc).
I really enjoyed the history of different inventors and great minds from ancient times to more modern times, such as Archimedes, Hero, Posidonius, Hipparchus, and Aristarchus (Copernicus used his theory from the 3rd century BCE to further prove heliocentrism, later Galileo). (Speaking of which, it wasn't until 1992 that the Catholic Church even admitted Galileo was right. I don't see how anyone can be okay with that, it is completely absurd.)
One of my only complaints about the book is that some of the mechanical elements described were a bit confusing and were difficult to get a full grasp on, especially as I've always been very visual with details such as those found in the Antikythera Mechanism. But overall a very intriguing book that makes me wonder yet again what else there is yet to be discovered, if ever discovered (the saddest possibility).

Decoding the Heavens: A 2,000-Year-old Computer and the Century Long Search to Discover Its Secrets by Jo Marchant is an exploration of the history and significance of the Antikythera Mechanism (/ˌæntɪkɪˈθɪərə/ an-ti-ki-theer-ə), an ancient mechanical calculator (also described as the first known mechanical computer) designed to calculate astronomical positions. Technological artifacts of similar complexity did not reappear until a thousand years later.
A work of caution. The story involves complicated descriptions of astronomical theory. Large amounts of detail on mechanical parts. And digressions on analytical instruments. These are all impossible to understand without drawings. I listened to the audio book. As such huge amounts of technical detail were lost. It plods along at a glacial pace. Personally, I got more out watching a documentary on the mechanism.

Absolutely fascinating story: an ancient Greek geared mechanism found in a shipwreck, and the struggle by various researchers to figure out what it was, working from a corroded and fragmented artifact. The writing is accessible and lively; at times a little too journalist-y for my tastes, but very readable. I now really want to go see the tower of the winds in Athens (as well as the Antikythera mechanism itself.)

The Antikythera device is one of the true marvels of human technology. Written with the flare of a detective story and the credibility of a science writer, Marchant's book is a fantastic introduction to a machine that has to be read about to be believed. Please see my blog for further remarks: Sects and Violence in the Ancient World.

Terrible dramatising writing. Maybe the author would rather write fiction. Dwelling on irrelevant minutiae, personal stories and general incompetence of the Greek government (who'd have thunk it). There are only a few pages left for the poor Antikythera which this book was meant to popularise.

"Decoding the Heavens: How the Antikythera Mechanism Changed The World" by Jo Marchant, narrated by Julie Eickhoff, is a fascinating exploration of one of the most enigmatic artifacts from ancient history. The audiobook delves into the discovery, analysis, and significance of the Antikythera Mechanism, an ancient Greek device that has often been described as the world's first analog computer.
Summary and Analysis
The narrative begins with the serendipitous discovery of the Antikythera Mechanism by sponge divers off the coast of the Greek island Antikythera in 1900. This seemingly unremarkable lump of corroded bronze turned out to be a complex and sophisticated device, dating back to around 100 BC. Marchant meticulously details the painstaking efforts of scientists over the past century to decode its purpose and workings.
Julie Eickhoff's narration brings a sense of wonder and excitement to the story, making the complex scientific and historical details accessible and engaging. Her clear and expressive voice helps to maintain the listener's interest, even through the more technical sections of the book.
Marchant's writing is both informative and captivating. She skillfully weaves together the historical context, the scientific investigation, and the personal stories of the researchers involved. The book is not just about the mechanism itself, but also about the people who dedicated their lives to understanding it. From the initial discovery to the latest advancements in imaging technology that have revealed its intricate gears and inscriptions, Marchant covers every aspect of the Antikythera Mechanism's story.
One of the strengths of the audiobook is its ability to convey the significance of the Antikythera Mechanism in the broader context of human history and technological development. Marchant argues that this device challenges our assumptions about the technological capabilities of the ancient Greeks. It suggests that they had a much more advanced understanding of astronomy and engineering than previously thought.
Themes and Insights
Several themes emerge throughout the audiobook. One is the theme of perseverance and curiosity. The scientists and historians who worked on the Antikythera Mechanism faced numerous challenges, from the physical difficulty of recovering and preserving the artifact to the intellectual challenge of deciphering its purpose. Their dedication and ingenuity are a testament to the human spirit of discovery.
Another theme is the interconnectedness of knowledge. The Antikythera Mechanism is a product of the ancient world's accumulated knowledge, drawing on the astronomical observations of the Babylonians, the mathematical theories of the Greeks, and the craftsmanship of Hellenistic engineers. This theme resonates with modern listeners, reminding us that our current technological advancements are built on the foundations laid by previous generations.
Narration and Production Quality
Julie Eickhoff's narration is a highlight of the audiobook. Her pacing is well-suited to the material, and she manages to convey both the technical details and the human stories with equal skill. The production quality is excellent, with clear audio and no noticeable flaws. The audiobook format is particularly effective for this book, as it allows listeners to absorb the complex information at their own pace.
Conclusion

1. Around 1900, a major find is found near Antikythera during a sponge search; for a long time, it is being searched by Greeks (who are recently, and not completely, independent and proud about it). For the first time in such cases, underwater archaeology produces results (a previous attempt to lift the traces of the Salamis battle was unsuccessful). However, the technology is still in its infancy: bends are ubiquitous and generally disregarded; underwater workers are never acknowledged. The 'mechanism' finds itself among other garbage from the site in a museum in Athens.
2. Soon, the remains of the device (damaged by neglect and air — a review of what happens to copper, bronze, iron and steel underwater and in other circumstances is included) were discovered, and, though it was virtually impossible to read (and there was a whole chunk of text without spaces), it was obvious that it was a very complex mechanism, something that did not seem probable for antiquity. Examples of gears were spotted in books (including a chariot 'taxometer', for example, and a number of inventions, such as the 'eternal screw', of Archimedes and his friends and followers), but there was nothing as complex as this. Researchers who contributed to the study were rear admiral John Theophanidis, the German expert Albert Rehm (who suffered during WWII and after, being a maverick opposed both to the Nazis and to the victors in the war), Rados, Rediadis etc. (an astrolabe, he claimed, even though it did not seem to be, being too complex and carried around in a box, like a typical onboard sea instrument). However, after the occupation and WWII the device sank into oblivion.
3. Decades pass; the chapter is spent in trying to define the origin of the wreck. Various methods are brought into play, including radiocarbon dating (which is faulty because the center of the trees is soon virtually dead even while the tree grows), underwater research (two attemps are made by Cousteau and his team at various times) and so on; the location could be Rhodos; Alexandria; Pergam — but probaby not the mainland or Athens. A stack of coins is found during the second Cousteau's attempt, and the wreck is tentatively dated to the 1st C BC.
4. Rewriting History. 4. A Heroic Reconstruction. 6. The Moon in a Box. 7. Mechanic's Workshop. 8. The New Boys. 9. A Stunning Idea. 10. Old Man of Syracuse.
All in all, research continues, and a new mysterious artefact is presented in another museum. People from London's Science Museum team up, an Austrialian makes an appearance, old ideas are discarded, the device is measured using cutting-edge new technologies (by a company who hopes to improve its technology to scan airplane propellers). After all the efforts, the decision is that it seems to be a specialized (but not used by specialists, because there are lots of instructions for lay people) device which defines the dates of eclipses and the like — a 19-year cycle is involved, after which the device should be manually reset. There are questions and mysteries that remain, but all in all, this is what it seems to be — and it certainly proves that the ancient world was not without its hi-end technology.
A very passionate and interesting book.

In the fall of 1900, half a dozen Greek sponge divers and their 20 rowers were returning from a season of diving in Tunisian waters. A storm caused them to take shelter at the small southern Greek island now known as Antikythera. Although their boat was already loaded with sponges, the divers decided to check the sea bottom when the storm abated. In doing so, they were surprised to encounter a pile of marble and bronze statues. They were soon joined by Greek archaeologists who confirmed that the sponge divers had found the wreck of an ancient merchant ship. They made headlines by bringing up bronze statues and other artifacts that can now be seen at the National Archaeological Museum in Athens. But this book tells the fascinating story of something else they found: a wooden case containing a conglomeration of corroded bronze wheels and gears that appeared to be some kind of scientific instrument.
The author explains why this so-called "Antikythera mechanism" has been called the earliest known computing device. Its extraordinary multiple functions were gradually decoded by generations of archaeologists, language experts, astronomers and mathematicians applying visual observations, carbon-14 dating, X-rays and ultimately CT scanning techniques. Experts from multiple countries contributed to solving the mystery, and the narrative is a page-turner. Even the famous Roman Cicero contributes to the author's explanation, which places the Antikythera device in the larger context of transferring computing technology through Byzantium to the Arab World and finally back to Europe in the late Middle Ages.
I recall being intrigued with the Antikythera device when I first saw it in Athens. Anyone with an interest in astronomy or the history of technology should find this book quite entertaining.

A book my 24-yr old child got me for Chanukah. It always interests me to see what others think I’ll enjoy reading (spoiler alert, most books). But they did hit my sweet spot of mechanical gadgetry, history, and intrigue.
One could have approached this subject with a direct, fact based treatment and the essential points would have been covered. Thankfully the author takes you on a largely chronological journey from the mechanism’s recovery from an ancient shipwreck off of the Antikythera coast in Greece in 1901 to present day.
The Antikythera mechanism, of course, draws us back to the first century BC as well as into the future. The intrigue that keeps the pages turning revolves around the lives of those pulled into the mechanism’s mystery and the burning desire to make sense of the tantalizing clues the 2,000 year-old corroded device presented.
The rivalries, friendships, and personalities at play, along with pushes on imaging technology, over more than a century lead to multiple theories about and replicas of the mechanism. I was satisfied that the introvert among those who bent their minds toward making sense of and replicating the mechanism is shown to be the closest to the mark.
The book brings to light how woefully ignorant we can be about past civilizations and their contribution to our own advancements. A subtle undercurrent is the idea that societies that do not appreciate knowledge for its own sake can slow or bring to a halt advancements in collective understanding that benefits us all. We owe our privileges to all who came before us; at least those among them who were actively working to improve understanding of the universe in which we live.
One could have approached this subject with a direct, fact based treatment and the essential points would have been covered. Thankfully the author takes you on a largely chronological journey from the mechanism’s recovery from an ancient shipwreck off of the Antikythera coast in Greece in 1901 to present day.
The Antikythera mechanism, of course, draws us back to the first century BC as well as into the future. The intrigue that keeps the pages turning revolves around the lives of those pulled into the mechanism’s mystery and the burning desire to make sense of the tantalizing clues the 2,000 year-old corroded device presented.
The rivalries, friendships, and personalities at play, along with pushes on imaging technology, over more than a century lead to multiple theories about and replicas of the mechanism. I was satisfied that the introvert among those who bent their minds toward making sense of and replicating the mechanism is shown to be the closest to the mark.

Якщо вам доводилося бувати в афінському археологічному музеї, то вам, напевно, запам'яталася давньогрецька бронзова статуя оголеного юнака на весь зріст – антикітерського ефебу. Його знайшли на кораблі, затонулому поблизу острова Антикітера у II столітті до н.е. Та вашу увагу мабуть не привернув інший (з першого погляду нічим не примітний) експонат з місця загибелі того самого корабля – антикітерський механізм.
Знахідки були передані до Національного археологічного музею Афін у 1900 р., але ніхто не звернув уваги на стародавній пристрій, який час і море перетворили на безформну, роз'їдену масу міді та дерева. Пілся того, як дерево за кілька місяців висохло і тріснуло, очам працівників музею з'явився дивовижний пристрій, що нагадує нутрощі будильника з системою шестерень різного розміру витонченої форми та ледь впізнаваємими давньогрецькими літерами – о��числювальний механізм, який зараз вважається однією з найважливіших археологічних знахідок людства. Але для чого він використовувася? Хто його виробив? Який був пункт призначення корабля, що його перевозив?
У книзі розповідається про історію Антикітерського механізму, його шлях із морського дна до сьогодення, інтриги та суперництво вчених за його розшифровку. У цій епічній пригоді читач зустрічається з історичними особистостями - від Архімеда до Жака Кусто, а також відкриває як сучасні технології допомогають у дослідженні давніх артефактів -від стародавньої Греції до ісламського світу та середньовічної Європи.

I had a blast reading this book. The author tells the fascinating story of the Antikythera mechanism. I liked reading about the scientists and enthusiasts (many of whom were interesting characters in their own right) who worked hard (and not always in sync; there were a lot of egos involved) to crack the mystery of this device. The final chapter about figuring about who could/would have made such a device was likewise interesting. This book will really get you to appreciate the ingenuity of these ancient people. It makes you wonder what they could have accomplished if things didn’t start going all the way to heck in the third century of the common era.
One point I disagreed emphatically with is a comment toward the end of the book where the author claimed that science was in decline during the early Roman Empire or that the Romans simply weren’t interested in scientific progress. I think Richard Cartier’s two books on the subject: Science Education in the Early Roman Empire and the Scientist in the Early Roman Empire are both good counter arguments to such claims.
Other than small quibbles like that, I whole heartedly recommend audiences interested in the history of science, lovers of antiquity, or those simply looking for a shirt, but entertaining read check this book out.

Somewhere in this book, Marchant refers to those beguiled by the Antikythera mechanism as "victims", and so was I in reading this book; I didn't want it to end. And I read with regret that she wonders if uncataloged and unread Islamic manuscripts may hold the key to additional information. Marchant's explanations, of everything from how carbon dating works to the meaning of the word "ecliptic" were invaluable for me. The explanations were clear and concise; the only trouble in comprehension might be an American reading the Britishisms. Some of the startling realizations for me were how many artifacts of the ancient world have only come down to us because of shipwrecks. And that astrology owes its life to astronomy and its detailed observations by the Babylonians in the West and doubtless others. It points to humankind's unerring capacity for polluting facts with fiction that is sometimes fanciful and sometimes destructive.

If you love, history, science, research, puzzles, exploration and philosophy you will love this book.
An excellent read, I couldn’t put it down.
Picked up at the London Science Museum where there was only 1 copy !
Wright’s presentation here is hilarious

What an inspirational man !
Now to watch Freeth’s documentary of the Antikythera mechanism on YouTube

This is a very engaging written account of the search to identify the purpose of the Antikythera artifact. Marchant blends together an interest in how driven so many of the protagonists are with an interest in ancient astronomy. This works very well for a reasonably casual-level read, which still respects the subject matter. That Wright clearly chose to collaborate with Marchant does show in the account, but she is scrupulous in trying to show all points of view as modern imaging narrows in the reveal of what the artefact does.
Any GLAM sector employee will likely wince at the absence of airconditioning in a few scenes. And the looting bit. And the dying divers bit - actually, that one goes for everyone. But Marchant manages to make this feel heroic all the same.

It´s a well written book.
Now, I know A LOT about the history and the capabilities of the AntiKythera "computer"...
BUT...
Despite the author tries, there is no explanation how a "Ferrari Murcealago" appeared in a Ford T ´25 enviroment.
Lost tech, a sudden ultra genius, who knows?
I hoped the book would describe the level of tech necessary to produce the mechanism in those times...
There is NO predecesor, the quoted ONES by the author are far away from the final product... it is something like "hey, they made a sun dial, they made a water clock... and they made... a COMPUTER!"
Nothing in-between!

A slow reveal spanning more than a century and a fascinating "cast" of obsessed characters propel this engrossing (nonfiction) historical mystery. In 1901, a perplexing artifact was discovered in an ancient shipwreck in the eastern Mediterranean. Jo Marchant, a science writer with a sense of humor, delivers each new story layer in context. We can appreciate how it took an array of persistent scientists, mechanical tinkerers, and historians, paired with advances in diving and computer technology to release the secrets of the antikytera device.

Good
I'm not very technical so some parts I skimmed over but even at that it was a good read. The illustrations in the Kindle addition appear haphazardly in the middle all of a sudden while your reading which is weird. Wish there was a better way to do this with the illustrations. Some things I even googled for a visual point of reference because I wasn't aware I'd eventually stumble upon the illustrations. All in all, pretty decent read.

I really enjoyed this. Jo's writing is accessible and straightforward to follow, and alongside the science she brings things to life by describing relevant people and telling their stories. I plan to read Cure and also the Human Cosmos [I think it is].
Although I wished for more detail at times, I came to trust Jo's judgement in telling a story, being accurate, and creating an enjoyable read. Probably more like 4.5 stars 😊

Reads Like a Detective Story.
I was inspired to purchase this book after seeing a video of the author giving a lecture on the Antikythera device. I was particularly impressed by the fact that she didn't use any notes. It is a thoroughly enjoyable read on a subject that could befall an boring. I have no hesitation in giving it five stars.

A fascinating story that explains how an ancient artifact was discovered and subsequently studied. It traces a journey of discovery that several researchers undertook to explain its function and history. That history of science is an intriguing plot that the author uses to weave together a gripping narrative. I chose this after reading the human cosmos by the same author.

安提基瑟拉儀的前世今生，同時也除魅所謂「橫空出世」的說法。沒有技術是一蹴可及，安提基瑟拉儀的現世使得很多西元前文獻記載要被務實看待，它背後的知識很可能是源自阿基米德「一顆球就能模擬日月行星運行」的設計和亞里斯多德用周轉圓解釋行星運行的模型。使用精密齒輪的技術在羅馬時期凋零，後在七八世紀間由伊斯蘭復興（齒輪日曆、大型水鐘），又在中世紀回流歐洲，與當時發明的擒縱器合流，大量附有刻度指針的複雜機械鐘在數十年間快速出現。
而安提基瑟拉儀的破解則是一百年間的跌宕起伏，好幾位不同領域的研究人員傾盡才智，將解密視為畢生任務，刻苦鑽研、辨讀、推論、試錯（還有背刺、佔功勞、搶發表），加上攝影與影像處理技術的革新，才能在2009年完整復原儀器的功能並模擬操作。

A great book on the Antikythera mechanism and its history & a good book on the history of science and ancient astronomy. Can be a little confusing at times with its descriptions of gear mechanics & astronomical months, but still reads super easily.

Ebook: narrative text comprised ~88% of the whole. Remainder was notes, etc.
An interesting (and true!) tale, and one that once again illustrates that ancient people were every bit as smart as modern people, something I think we often forget.
