World’s First Computer From Ancient Greece Discovered In Aegean Sea

Some time ago, I first wrote about a mystery unfolding in the Aegean Sea. To be more specific an underwater area off the island of Antikythera. A mystery slowly revealing more and more of its secrets.

An extraordinary mystery that really begins in 200 BC, when a Roman ship sailed on a voyage. Where it came from and where it was going nobody knows for certain. But somewhere between Greece and Crete, it ran into a storm and sank. And for more than two thousand years the treasures it carried literally faded into history. Entombed in the sandy bottom of the ocean.

Fast forward to only 100 years ago, when a group of sponge divers make a chance discovery. They see the hand of an ancient statue protruding eerily from the silt. These sponge divers stumbled on the wreck of that ancient Roman ship. It is the largest ancient ship wreck to be discovered. Even though they could only spend a short time on the bottom, because of the depth, they still managed to collect a vast array of artefacts. It was an amazing but eclectic collection of bits and pieces: bronze and marble statues, jewellery, glass and coins. The statues were beautifully crafted and life-like despite the ravages of time and the sea. The glassware crafted to an exacting standard and brightly coloured. The treasure is the sum of many parts but not the whole. Very few items were complete. And of course that led to much speculation about what kind of ship she was. Was it a treasure ship making a delivery to a King or High Priest? Was it a plunder ship carrying the spoils and trophies of war? Or, was it just laden with an assortment of trinkets destined for sale in some distant market?

But one particular item they discovered, at first glance looked like a corroded lump of bronze cogs and wheels. Because it was bronze, it survived well in the sea but didn’t look like anything, anyone had seen before. A lot of years passed before scientists finally took a closer look to see if it could be identified.

The first job, get it X-rayed. And when they did. it looked way more complicated than first thought. There were wheels within wheels. But what exactly was it? It slowly dawned on scientists this was one of the most sophisticated devices ever discovered from ancient times. Forget about Apple and Microsoft. They were looking at the world’s first computer, an analogue computer that did calculations. As far as anyone knows, the only example of its kind anywhere in the world. But how did it work? After further examination, the scientists determined it was an ancient timepiece working as an astronomical calculator. A calculator, or mechanical device, predicting movement of stars and planets. As one astrophysicist said, the device makes mechanical what was known for centuries about astronomical cycles. These cycles predict eclipses by the moon and the sun and are used to produce workable calendars. This hand-cranked device, more than likely predicted which city would host the Olympic Games, as well as tracking movement of planets, for prophecies and religious ceremonies.

Just to put this into context. This is something built more than two thousand years ago. The kind of skill and complexity needed for manufacture would not become evident until the 14 Century. Beyond being ahead of its time, the device could well be one of the greatest archaeological discoveries of all time. Scientists think it was built for a wealthy person, for a bit of fun.

The scientific community is very excited principally because they believe they only have half the story. Another half of the device or devices, remains on the bottom of the Aegean sea, waiting to be found. So scientists have no idea how complicated this device could potentially be, or even how many there are until they discover the rest of it. One set of gears and cogs doesn’t match the rest so there is more of the device or devices to be discovered.

But as time goes on scientists are learning more and more about what is being called the Antikythera mechanism. Some of the bronze work contains inscriptions and one word stands out. The Greek word for Cosmos. Scientists believe another metal plate may actually contain an instruction manual for using the device because it details different gear settings.

In a very recent development, scientists now say the device may be much older than first thought. The latest theory it dates from around 200 BC, and not 60 BC as first thought, which ties the device to two of history’s greatest minds, Archimedes and Hipparchus, both astronomers and mathematicians.

But one of the great ironies of this discovery is that true cutting edge technology is being invented for the express purpose of discovering the rest of this ancient example of high tech wizardry and whatever else might be lurking at the site. A $1.7 million diving suit, which acts like a wearable submarine, developed so an archaeologist can use it to explore the wreck site. There are pedals at the feet of the suit to allow the wearer to literally fly through the water powered by thrusters built into the suit’s backpack. The suit’s arms allow for free movement and instead of using their hands, archaeologists recover objects using mechanical pincers. The suit has breathing and communication systems and a carbon dioxide scrubber, which means a diver can stay at depth for long periods.

The whole expedition is costing millions of dollars, partly sponsored by a Swiss watchmaker. The Swiss are people used to dealing with complicated machinery so no surprise they are curious to know more about what makes this device tick.

So far 82 fragments of the Antikythera mechanism were recovered from the wreck. If it turns out to be some rich person’s toy it will be one the most complicated toys ever devised, a genuine forerunner of today’s modern computers. Move over Apple and Microsoft. Forget California, the first Silicon Valley was Ancient Greece.

The World’s First Computer

Are you ready to be amazed and astounded? OK I may be overstating it a tad. But everyone loves a good mystery and this one is certainly up there with the best. In 60 BC, a Roman ship sailed on a voyage. Where it came from and where it was going to nobody knows. But somewhere between Greece and Crete, it ran into a storm and sank. And for more than two thousand years the treasures it carried faded into history. Entombed in the sandy bottom of the ocean. But you know what? This story really begins 100 years ago. That’s when a group of sponge divers saw a spooky looking hand sticking out of the silt. It was in an area off the island of Antikythera in the Aegean sea at a depth of 75 meters.

The hand was part of an ancient statue. These sponge divers could only spend a short amount of time on the bottom because of the depth but they managed to collect a treasure trove of artifacts. It was an amazing but eclectic collection of bits and pieces. There were bronze and marble statues, jewellery, glass and coins. The statues were beautifully crafted and life-like despite the ravages of time and the sea. The glassware crafted to an exacting standard and brightly colored. The treasure trove could best be described as the sum of many parts but not the whole. Very few of the items were complete. And of course that has led to much speculation about what kind of ship this was. For example, was it a treasure ship making a delivery to a King or a High Priest? Was it a plunder ship carrying the spoils and trophies of war? Or, was it just laden with an assortment of trinkets no longer wanted and destined for sale in some distant market?

But there was one item discovered that at first glance looked like a corroded lump of bronze cogs and wheels. Because it was bronze, it survived well in the sea but it didn’t look like anything anyone had every seen before. A lot of years passed before scientists decided to take a closer look at the object to see if they could identify it.

The first job was to get it X-rayed. And when they did that it looked way more complicated than they first thought. There were wheels within wheels. But what exactly was it? It slowly dawned on scientists that what they were looking at was in fact one of the most sophisticated devices ever discovered from ancient times. Forget about Apple and Microsoft. What they were looking at was the world’s first computer. It was an analog computer that did calculations. As far as anyone knows, this is the only example of its kind anywhere. But what did it actually do? The scientists finally determined it was an ancient timepiece. A timepiece, that worked as an astronomical calculator. A calculator, or mechanical device, that predicted the movement of the stars and the planets.

This hand-cranked device was more than likely used to predict which city was due to host the Olympic Games as well as to track the movement of the planets for prophecies and religious ceremonies

Just to put this into context. We are talking 60 BC. The kind of skill and complexity needed to manufacture it did not become evident until the 14 Century.This was ahead of its time by a considerable margin.Centuries. The feeling is that the device probably belonged to a wealthy person who used it for a bit of fun. The scientific community is very excited because they believe they only have half the story. The other half of the device, they believe, is still lying at the bottom of the Aegean sea waiting to be found. So in all honesty, you could say scientists still don’t fully understand how complicated this device could potentially be until they discover the rest of it. One set of gears and cogs doesn’t match the rest so there is clearly more to come.

But as time goes on scientists are learning more and more about the device, which has been called the Antikythera mechanism. Some of the bronze work contains inscriptions. One word stands out. It is the Greek word for Cosmos. Scientists believe another metal plate may actually contain an instruction manual for using the device. It details different gear settings.

But one of the great ironies of this discovery is that true cutting edge technology has now been invented for the express purpose of discovering the rest of this ancient example of high tech wizardry and whatever else might be lurking at the site.

The suit’s arms allow for free movement and instead of hands, objects will be recovered using mechanical pincers. The suit has breathing and communication systems and a carbon dioxide scrubber, which means the wearer can stay at depth for an extended time

The whole expedition will cost $3 million and, is being partly sponsored by a Swiss watchmaker. I guess they are also curious about what makes this device tick if you will forgive my punditry.

And now a new search will begin to find the rest of the mechanism.Scientists are certain that it’s down there somewhere. It’s only when they discover this missing second piece of the device that scientists will truly know what they are dealing with. At the risk of talking it up this could become one of the most significant archeological discoveries of the 21st Century.
