Sorghum was domesticated from its wild ancestor more than 5,000 years ago, according to archaeological evidence uncovered by University College London archaeologist Dorian Fuller and colleagues in Sudan.

Sorghum (Sorghum bicolor) is a native African grass that was utilized for thousands of years by prehistoric peoples, and emerged as one of the world’s five most important cereal crops, along with rice, wheat, barley, and maize.

For a half century scientists have hypothesized that native African groups were domesticating sorghum outside the winter rainfall zone of the ancient Egyptian Nile Valley — where wheat and barley cereals were predominant — in the semi-arid tropics of Africa, but no archaeological evidence existed.

The newest evidence comes from an archaeological site near Kassala in eastern Sudan, dating from 3500 to 3000 BC, and is associated with the Butana Group culture.

“This new discovery in eastern Sudan reveals that…

The Antikythera mechanism is a 2,100-year-old computer:

Antikythera mechanism Wikipedia

116 years ago (1902), divers found a chunk of bronze off a Greek island. It has radically changed our understanding of human history.

One hundred sixteen years ago, an archaeologist was sifting through objects found in the wreck of a 2,000-year-old vessel off the Greek island Antikythera. Among the wreck’s treasures, fine vases and pots, jewellery and, fittingly enough, a bronze statue of an ancient philosopher, he found a peculiar contraption, consisting of a series of brass gears and dials mounted in a case the size of a mantel clock. Archaeologists dubbed the instrument the Antikythera mechanism. The genius — and mystery — of this piece of ancient Greek technology is that arguably it is the world’s first computer. If we gaze inside the machine, we find clear evidence of at least two dozen gears, laid neatly on top of one another, calibrated with the precision of a master-crafted Swiss watch. This was a level of technology that archaeologists would usually date to the sixteenth century AD. But a mystery remained: What was this contraption used for? 

To archaeologists, it was immediately apparent that the mechanism was some sort of clock, calendar or calculating device. But they had no idea what it was for. For decades, they debated. Was the Antikythera a toy model of the planets or was it a kind of early astrolabe, a device which calculates latitude?

IMAGE ancient

At long last, in 1959, Princeton science historian Derek J. de Solla Price provided the most convincing scientific analysis of this amazing device to date. After a meticulous study of the gears, he deduced that the mechanism was used to predict the position of the planets and stars in the sky depending on the calendar month. The single primary gear would move to represent the calendar year, and would, in turn, activate many separate smaller gears to represent the motions of the planets, sun and moon. So you could set the main gear to the calendar date and get close approximations for where those celestial objects in the sky on that date. And Price declared in the pages of Scientific American that it was a computer: “The mechanism is like a great astronomical clock ... or like a modern analogue computer which uses mechanical parts to save tedious calculation.”

It was a computer in the sense that you, as a user, could input a few simple variables and it would yield a flurry of complicated mathematical calculations. Today the programming of computers is written in digital code, a series of ones and zeros. This ancient analog clock had its code written into the mathematical ratios of its gears. All the user had to do was enter the main date on one gear, and through a series of subsequent gear revolutions, the mechanism could calculate variables such as the angle of the sun crossing the sky. As a point of referencdee, mechanical calculators using gear ratios to add and subtract, didn’t surface in Europe until the 1600s. 

Since Price’s assessment, modern X-ray and 3D mapping technology have allowed scientists to peer deeper into the remains of the mechanism to learn even more of its secrets. In the early 2000s, researchers discovered text in the guise of an instruction manual that had never been seen before, inscribed on parts of the mechanism. The text, written in tiny typeface but legible ancient Greek, helped them bring closure to complete the puzzle of what the machine did and how it was operated.
 
The mechanism had several dials and clock faces, each which served a different function for measuring movements of the sun, moon, stars, and planets, but they were all operated by just one main crank. Small stone or glass orbs moved across the machine’s face to show the motion of Mercury, Venus, Mars, Saturn, and Jupiter in the night sky and the position of the sun and moon relative to the 12 constellations of the zodiac. Another dial would forecast solar and lunar eclipses and even, amazingly enough, predictions about their colour. Today, researchers surmise that different coloured eclipses were considered omens of the future. After all, the ancient Greeks, like all ancients, were a little superstitious. 

The mechanism consisted of:
- a solar calendar, charting the 365 days of the year 
- a lunar calendar, counting a 19 year lunar cycle 
- a tiny pearl-size ball that rotated to illustrate the phase of the moon, and another dial that counted down the days to regularly scheduled sporting events around the Greek isles, like the Olympics.  The mechanics of this device are absurdly complicated. A 2006, in the journal Nature, a paper plotted out a highly complex schematic of the mechanics that connect all the gears. 

Researchers are still not sure who exactly used it. Did philosophers, scientists and even mariners build it to assist them in their calculations? Or was it a type of a teaching tool, to show students the math that held the cosmos together? Was it unique? Or are there more similar devices yet to be discovered? To date, none others have been found.

Its assembly remains another mystery. How the ancient Greeks accomplished this astonishing feat is unknown to this day. Whatever it was used for and however it was built, we know this: its discovery has forever changed our understanding of human history, and reminds us that flashes of genius are possible in every human era. Nothing like this instrument is preserved elsewhere. Nothing comparable to it is known from any ancient scientific text or literary allusion,” Price wrote in 1959. “It is a bit frightening, to know that just before the fall of their great civilization the ancient Greeks had come so close to our age, not only in their thought, but also in their scientific technology.”

There are amazing fully operational modern versions of the Antikythera Mechanism, such as these:

Researcher Cites Ancient Minoan-era Computer:

minoan_computer

This Minoan object preceded the heralded Antikythera Mechanism. If we take the definition of a computer as being a device that can compute, even at the most basic level, then this computer meets the bottom line of the definition.

A stone-made matrix has carved symbols on the surface of this computer related with the Sun and the Moon, serving as a cast to build a mechanism that functioned as an analog computer to calculate solar and lunar eclipses. The mechanism was also used as sundial and as an instrument calculating the geographical latitude. In this sense, it predates the astrolabe, an instrument of some antiquity (i.e. since Minoan times).

Researcher Cites Ancient Minoan-era Computer:

Researcher Minas Tsikritsis who hails from Crete — where the Bronze Age Minoan civilization flourished from approximately 2700 BC to 1500 century BC — maintains that the Minoan Age object discovered in 1898 in Paleokastro site, in the Sitia district of western Crete, preceded the heralded “Antikythera Mechanism” by 1,400 years, and was the first analog and “portable computer” in history.

“While searching in the Archaeological Museum of Iraklion for Minoan Age findings with astronomical images on them we came across a stone-made matrix unearthed in the region of Paleokastro, Sitia. In the past, archaeologists had expressed the view that the carved symbols on its surface are related with the Sun and the Moon,” Tsikritsis said.

The Cretan researcher and university professor told ANA-MPA that after the relief image of a spoked disc on the right side of the matrix was analysed it was established that it served as a cast to build a mechanism that functioned as an analog computer to calculate solar and lunar eclipses. The mechanism was also used as sundial and as an instrument calculating the geographical latitude.

For the definition of the astrolabe, see

astrolabe Wikipedia

Persian models dating as far back as the eleventh century have been found, and Chaucer wrote a Treatise on it in the late 1300s. But different models of astrolabes date as far back as somewhere around 400 BCE, when Theodora of Alexandra wrote a detailed treatise on the astrolabe. Historically, many different versions of the astrolabe have arisen since then. For a full account of astrolabes, consult Wikipedia: Astrolabe. But the whole point is that the Minoan computer predates even the earliest of these (vide supra), by at least 1,000 years!

By the Elizabethan era it consisted of a large brass ring fitted with an alidade or sighting rule:

Mariner's Astrolabe Francisco de Goes 1608

Notice the astonishing resemblance between the Minoan computer and the astrolabe from 1608 above.

Translation:

1. Wodiyeya Deminiya l [NOTE 1]
2. Mano * [2] + Arekasadaraqe = Mano * and Arekasadara 2
3. Risura + Qotaqe = Risura and Qota 2
4. Eritupina  + Teodoraqe = Eritupina and Theodora 2
5. Otowowije +  tukateqe = Otowowije and her daughter 2
6. Anea + tukateqe = Anea and her daughter 2
7. Pirowona + Kiraqe ** [3] = Pirowona and Kira 2
8. Pukaro * [2] + Ketideqe = Pukaro and Kedite 2
9. ? Scratched ...?moqe = and …?mo 2
10. ... Maraqe = and Mara 2
11. scratched ? 1
12. ? + Kiraqe ** = and Kira 2 [3]
13. blank

NOTES:
[1] Since in Line 1, Wodiyeya Deminiya l is followed by the number 1, this can only be one person. Thus, her name is  Wodiyeya Deminiya.
[2] * Mano * and * Pukaro * are men's names. Line 11 also refers to only 1 person, but the name of the person is truncated, i.e. it no longer appears on the tablet.
[3] ** kira ** - or Kira = Ki/ra or Kei/ra = onomastics. Also appears on a Linear A tablet as Kira (onomastics). Complements of Rita Roberts
