Sophisticated ancient computer bedazzles

What a marvel. Only have time to excerpt extracts below at present but couldn’t pass up highlighting this amazing discovery of extraordinary ancient technical sophistication.

A 2,000-year-old mechanical computer salvaged from a Roman shipwreck has astounded scientists who have finally unravelled the secrets of how the sophisticated device works.The machine was lost among cargo in 65BC when the ship carrying it sank in 42m of water off the coast of the Greek island of Antikythera. By chance, in 1900, a sponge diver called Elias Stadiatos discovered the wreck and recovered statues and other artifacts from the site.

Since its discovery, scientists have been trying to reconstruct the device, which is now known to be an astronomical calendar capable of tracking with remarkable precision the position of the sun, several heavenly bodies and the phases of the moon. Experts believe it to be the earliest-known device to use gear wheels and by far the most sophisticated object to be found from the ancient and medieval periods.

One of the remaining mysteries is why the Greek technology invented for the machine seemed to disappear. No other civilisation is believed to have created anything as complex for another 1,000 years. One explanation could be that bronze was often recycled in the period the device was made, so many artefacts from that time have long ago been melted down and erased from the archaelogical record. The fateful sinking of the ship carrying the Antikythera Mechanism may have inadvertently preserved it. “This device is extraordinary, the only thing of its kind,” said Professor Edmunds. “The astronomy is exactly right … in terms of historic and scarcity value, I have to regard this mechanism as being more valuable than the Mona Lisa.” The research, which appears in the journal Nature today, was carried out with scientists at the National Archaeological Museum of Athens where the mechanism is held and the universities of Athens and Thessaloniki.

It seems clear, Dr. Charette said, that “much of the mind-boggling technological sophistication available in some parts of the Hellenistic and Greco-Roman world was simply not transmitted further,” adding, “The gear-wheel, in this case, had to be reinvented.”

    Begs the question what else lies beneath the surface of our collective unconscious?

    Its doom was sealed 11,000 years ago at the end of the last ice age, when rising seas swamped it along with six other nearby islands, Collina-Girard said.

    Today the islands are shoals crouched anywhere from 175 feet to 410 feet (53 to 125 meters) below the ocean’s surface along the coasts of Spain and Morocco.

    Collina-Girard said the legend of Atlantis likely grew as storytellers embellished it on its way to Plato and Athens 9,000 years later. He compared the story to Noah’s flood, an idea that he said probably arose after the rising Mediterranean overran the Bosporus 7,600 years ago to cascade into what is now the Black Sea basin.

    “It is the same thing,” Collina-Girard said. “Everywhere in the Middle East, Europe, and Asia people have stories that speak of the time when the sea came in.

    “Atlantis is another discrete story of the flood.”

    And evidence was recently found of actual fire and brimstone at Sodom and Gomorrah.

Timely Reminders

"Those who crusade, not for God in themselves, but against the devil in others, never succeed in making the world better, but leave it either as it was, or sometimes perceptibly worse than what it was, before the crusade began. By thinking primarily of evil we tend, however excellent our intentions, to create occasions for evil to manifest itself."
-- Aldous Huxley

"The only war that matters is the war against the imagination. All others are subsumed by it."
-- Diane DiPrima, "Rant", from Pieces of a Song.

"It is difficult
to get the news from poems
yet men die miserably every day
for lack
of what is found there"
-- William Carlos Williams, "Asphodel, That Greeny Flower"
