World’s Oldest ‘Computer’ May Be Older Than Previously Thought

Since its discovery over a century ago, the Antikythera Mechanism has had scholars scratching their heads over how the Greeks managed to build a mechanical computer a hundred years before the birth of Christ and thousands of years before anything similar. But now things have become even stranger as researchers claim that it’s over a hundred years older than previously believed and may have been built by a famous hand.

The Antikythera Mechanism was discovered in 1901 by sponge divers off the Greek island of Antikythera. At first, not much was made of it, but after the coral-encrusted, corroded mass of bronze gears was later studied using x-rays, gamma rays, and neutrons, and then reconstructed, it turned out to be something astonishing.

The device at first was thought to be some sort of surprisingly early clock, but then it turned out to be the oldest computer known. In fact it was an analog astronomical computer based on the principle of the differential calculator that uses gear trains as a way of performing complex calculations. On further study, the device proved capable of calculating, among other things, the position of the planets, sidereal time, and eclipses.

And all of this by using technology that was never realized to exist in the ancient world and after it vanished, didn’t reappear until the 14th century. Even today the device sparks interest as the design is adapted to not only museum exhibits, but also watches.

Lessons from the Last Time Civilization Collapsed

Adam Frank | NPR.org | Aug 19 2014

Consider this, if you would: a network of far-flung, powerful, high-tech civilizations closely tied by trade and diplomatic embassies; an accelerating threat of climate change and its pressure on food production; a rising wave of displaced populations ready to sweep across and overwhelm developed nations.

Sound familiar?

While that laundry list of impending doom could be aimed at our era, it’s actually a description of the world 3,000 years ago. It is humanity’s first “global” dark age as described by archaeologist and George Washington University professor Eric H. Cline in his recent book 1177 B.C.: The Year Civilization Collapsed.

1177 B.C. is, for Cline, a milepost. A thousand years before Rome or Christ or Buddha, there existed a powerful array of civilizations in the Near and Middle East that had risen to the height of their glory. Then, fairly suddenly, the great web of interconnected civilizations imploded and disappeared.

The question that haunts Eric Cline is why. What drove such a complex set of societies to all perish almost all at once? The answers and its lesson, Cline argues, are a story we moderns should not ignore. When I asked him about the parallels between 1177 B.C. and A.D. 2014, Cline responded:

“The world of the Late Bronze Age and ours today have more similarities than one might expect, particularly in terms of relationships, both at the personal level and at the state level. Thus, they had marriages and divorces, embassies and embargoes, and so on. They also had problems with climate change and security at the international level. These are not necessarily unique to just them and us, but the combination of similar problems (climate change and drought, earthquakes, war, economic problems) at the very same time just might be unique to both.”

The Late Bronze Age that Cline is interested in stretches from about 1500 B.C. to 1100 B.C. The Bronze Age itself, as opposed to the Stone Age before it, begins somewhere around 3000 B.C. At that point, people developed sophisticated metallurgy techniques allowing them to mix copper and tin into an alloy — bronze — strong enough for serious sword blades and other goods. It is in the Bronze Age that city building, and the sprawling kingdoms they engendered, begins in earnest. Egypt of the pharaohs was a Bronze Age civilization as was the Babylonian empire.

It was the transport of copper and tin for bronze that helped establish complex trade networks. Grain and manufactured goods also became part of that transportation web. Alliances between city-states followed. In this way, the Egyptians, Hittites, Canaanites, Cypriots, Minoans, Mycenaeans, Assyrians and Babylonians became the economic powerhouses of the ancient world — what Cline calls the “Group of 8.” Together they built the first version of a “global” culture using long-distance economic and military partnerships that required advanced — for its day — technologies.

So what took all these cultures down at the same time? The story begins, but does not end, with climate change.

The evidence that a prolonged shift in climate was a factor in bringing down the Mediterranean Bronze Age comes from a number of studies, including one published in 2013, showing that cooling sea surface temperatures led to lower rainfall over inland farming areas. Pollen analysis from sea sediments also indicates a fairly rapid transition to a drier climate during this period that includes the Late Bronze Age collapse.

What followed were drought, scarcity and desperation. Ancient voices, preserved in stone, tell the human side of the climate change story. A letter from a commercial officer living in the starving, inland city of Emar begs the recipient in his hometown of Ugarit, in northern Syria, to bring aid quickly. “There is famine in your [i.e. our] house; we will all die of hunger. If you do not arrive quickly, we ourselves will die of hunger. You will not see a living soul …”

And with famine came migration and wars. The scourge of the era was the mysterious “Sea Peoples” who had swept across the region. According to Cline, it is likely that the marauding Sea Peoples came from the western Mediterranean and “were probably fleeing their island homes because of the drought and famine … moving across the Mediterranean as both refugees and conquerors.”

The wars took their own toll. “Be on the lookout for the enemy and make yourself very strong!” proclaims a letter to the King of Ugarit near the end. The warning appears to have arrived too late. Another letter tells of the army’s humiliation. “The city was sacked. Our food in the threshing floors was burned and the vineyards were also destroyed. Our city is sacked. May you know it! May you know it!”

For Cline, climate change — along with the famines and migration it brought — comprised a “perfect storm” of cataclysms that weakened the great Bronze Age “global” culture. But the final blow, the deepest reason for the collapse, may have come from within the very structure of that society.
