Ancient Antikythera wreck

Researchers to revisit ancient Antikythera wreck using new technology

(Read the article on one page)

The Antikythera wreck in the Aegean Sea is a world-famous underwater archaeological site thrown into the spotlight in 1900 when researchers discovered an incredible mechanical device, now known as the Antikythera mechanism , which dates back 2,000 years.  The device consists of a complex combination of gears and took decades for scientists to decipher its functionality – it shows the positions of the sun, moon, and planets as they move through the zodiac, predicts solar and lunar eclipses, and even marked key events such as the Pan-Hellenic games.

Archaeologists suspect that there is much more to be found within the Antikythera wreck, named after the Greek island Antikythera, however, the dangerous conditions of the submerged vessel have so far prevented researchers exploring the site fully. The wreck is located at an extreme depth of 120 metres, resulting in the death of one diver and others being paralyzed from decompression sickness. Subsequent attempts more recently have led to more discoveries, but time constraints have prevented a thorough study of the wreck.

According to a new report in New Scientist , marine archaeologists with the American Museum of Natural History have now come up with a solution – they will use a high-tech exosuit developed by Nuytco research, which allows divers to descend to 300 metres for hours at a time without the need for decompressing upon returning to the surface. The exosuit, which is made mostly of aluminium, works like a submarine. It has 1.6 horsepower thrusters, an oxygen replenishment system, LED lights, cameras, and is tethered to the surface with a fiber optic gigabit Ethernet that allows for two-way communications, a live video feed, and monitoring of the suit and its wearer.

Brendan Foley, co-director of field operations at WHOI's Deep Submergence Laboratory, believes that the Antikythera shipwreck still holds many secrets and the suit will help find them. A preliminary survey last year showed artefacts scattered over an area 50 metres by 10 metres, and even revealed a previously unknown shipwreck alongside the first one.

"We have feet, arms and the crest of a warrior's helmet from statues recovered in 1900 – maybe we'll get lucky and find the rest of them," says Foley. "But for me, the mechanism is what sets this wreck apart. It's the questions it opens up about the history of science and technology that fire my imagination."

The problem is that we map according to our cultural paradigm and not theirs.

We could be in a position to understand so much more should we be able to view the findings according to their knowledge or wisdom.

"Walk a mile in my shoes".

I understand that there could have been a handle which enabled the device to be set at a particular day and time.
Now I have my computer to bring up a chart of the sky on a particular day, time and place. Try 'Astrolog' it's basic but free.

One of a few most fascinating finds ever as the machine was hand made to a standard that today would be a humungous task. The cog teeth were cut, with precision, by hand.

It also shows signs of being repaired twice which suggest that it was in constant use,

Yes, the point is that there have perhaps been many civilis(z)ations that have superceeded ours but in different directions of technology and understanding.

With all of the complications of the movement of the planets, eliptical orbits and retrogrades, for example, this is a pinnacle of acheivement.

I don't believe that today it would be possible to build such a machine without the knowledge which today only very few have, it would take a team of very clever people with very different skills.

I believe that the wreck should be thoroughly mapped and excavated.It holds a lot of answers to a lot of puzzles.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
