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?

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:


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:

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

5 more putative proto-Greek or pre-Greek Minoan Linear A words, MI-MU & 1 is a winner!


The preceding table lists 5 more  putative proto-Greek or pre-Greek Minoan Linear A words from MI-MU.  Of these 5, [3] mita = “minth”, is by far the most compelling because it is identical to the Mycenaean Linear B word, right down to orthography. Both words may be either proto-Greek or part of the pre-Greek substratum. The next most convincing decipherment is [1] mini, which very likely means “month”, and which is probably proto-Greek or proto-Mycenaean. [4] muko = “recesss/corner”  also makes quite a lot of sense, in view of the fact that it appears to be an architectural term. Such terms are relatively common in Mycenaean Linear B; so it stands to reason that they may also be so in Minoan Linear A.  [5] musaja might possibly mean “shut/closed”, if it is an adjective, but this is a bit of stretch.

Sublime Sappho. The moon has set & the Pleiades (in Aeolic Greek, Linear B, Linear C, English & French): Click to ENLARGE

Sappho poetry Elihu Vedder 1836-1923 The Pleiades 1885

This is the first of many exquisite poems by the sublime Sappho (ca. 630-570 BCE), who was considered by the ancient Greeks to be second only to Homer, as well as the greatest lyric poet of their age. Indeed, even today, a great many poets and poetry critics, including myself, consider her to hold this exalted station still. You will all see this for yourselves as I post one after another of her exalted lyrics. I have decided to go all the way, by presenting you each poem in the original Aeolic Greek, as well as in Mycenaean Linear B & Arcado-Cypriot Linear C, and even English and French! Throughout history, to this very day, no one has ever done this. I am the first. I am so in awe Sappho’s consummate skill and artistry that I will do anything to broadcast her name and her sublime poetry to the whole world.

This particular poem is my absolute favourite. It flows so naturally in Aeolic Greek that it washes over me, emotionally and spiritually. Like Italian, Aeolic Greek is superbly suited for lyric poetry, as it has no aspirates. Aspiration can and sometimes does sound harsh in lyric poetry. Aeolic Greek is notable for its sublime melody. If you could only hear this stunning poem, even if you could not even read Aeolic Greek, the Harmony of the Spheres would fairly floor you. Sappho knew this perfectly well. Her lyrics were, of course, sung to the accompaniment of the lyre. I have never read any lyric poet in any language (English, French, Spanish, Italian, German or Russian) who has ever been able to rival her consummate artistry. I adore her.

Simeon Solomon 1840-1905 A Study of Sappho 1862

A few linguistic notes:

Being an East Greek dialect, Aeolic Greek is related to both the Mycenaean & Arcado-Cypriot dialects. There are many striking similarities and some notable differences in these three dialects.

Mycenaean Greek in Linear B:

Mycenaean Greek has no L series of syllabograms. The R series must be substituted, hence “serana” for Aeolic “selanna”. Since Linear B is an open syllabary, in which all syllabograms must end with a vowel, it is impossible to spell any word with two consecutive consonants, hence the last syllable of “serana” has only 1 N. For the same reason, final consonants, which are normative in almost all ancient Greek dialects, must be omitted in Mycenaean Greek. Hence, we have “me” for “men”. It is difficult to express the plural in Mycenaean Greek. However, there are precedents. The plural of “apore” (amphora) is “aporewe”. This allows us to write the Pleiades as “Periadewe”.

Arcado-Cypriot Linear C:

Similar bizarre (parallel) spelling conventions plague Arcado-Cypriot Linear C . Unlike Linear B, which has a dental D series of syllabograms, Linear C lacks it, and must substitute the dental T series. On the other hand, Linear C has both an L and an R series, and so both liquids can be accounted for. Since documents in alphabetic Arcado-Cypriot must express the final consonant, in line with almost all other ancient Greek dialects, Linear C has no choice but to resort to the opposite strategy from Mycenaean Linear B for the orthography of the ultimate, when it is meant to express the dative singular, the nominative plural and for all other Greek words ending with a consonant. The consonant must be expressed in Linear C, since it is always written in the alphabet. This is absolutely de rigueur, since many documents are simultaneously composed in Linear C and in the alphabet. In order to achieve this, Linear C has no choice but to use syllabograms, which still end in a vowel. It neatly skirts this annoying problem by expressing the ultimate consonant, following it with a filler vowel. A weird solution, but it works. If it works, it works. No hay problema nada.
Hence, we have “mene” for “men”, which is the opposite of “me” for “men” in Linear C. Likewise, the plural is always clearly expressed, as in “peleitese”, where Linear C must also insert a final filler vowel, in most cases SE (to express the consonantal plural in sigma), as well as NE for all nouns ending in the consonant N. Such nouns are extremely common in ancient Greek dialects. Notice also the “te” in “peleitese”, since Linear C has no D series of syllabograms. On the other hand, both Mycenaean Linear B & Arcado-Cypriot have no G series of syllabograms.

Mycenaean Linear B must substitute either the K or the Q series. Arcado-Cypriot has no guttural Q series either, so all words with G + vowel must be expressed by K + vowel, hence “eko” for “ego” in both Linear B & C. I can hear you who read ancient Greek well or who are ancient Greek linguistics loudly protest that there were no personal pronouns in either Linear B or Linear C. And you are right. However, I had to take liberties with the Aeolic Greek, because it does use personal pronouns, and frequently. As for the likelihood that Mycenaean Greek would have used the Q series of syllabograms to express words with guttural G + vowel, I would readily grant that this may have been true, except for one critical consideration. Mycenaean & Arcado-Cypriot were the closest ancient Greek dialects by far, being kissing cousins. So if Arcado-Cypriot expresses G + vowel with the guttural K series of syllabograms, it stands to reason that it is more likely than not that Mycenaean Greek must have done the same thing. But there is no guarantee of this. Still, the Q series of syllabograms would have fit the bill just as well.

And there you have it.
