Inventions by Hero of Alexandria

The best-known works by Hero of Alexandria are his Pneumatica and Mechanica in which he described how “Automata” actually works. “Automata” is a Greek word meaning as much as “self-moving”, “self-acting” or “self-willed” which is familiar in our modern world. It may be debated whether the inventions were truly his or if he collected them from other sources available at the Library of Alexandria.  

[Reconstruction inside of Alexandria's Library]

Hero lived in the 1^st century BC, and his Pneumatica was widely read far into the Middle Ages. More than 100 manuscripts have survived, illustrating how ancient texts can live a long life. The earliest surviving copy is kept in the Bibliotheca Marciana in Venice, Italy, and dates from the 13^th century, i.e., 1400 years after it was initially written! 

The inventor’s Mechanica has survived thanks to one single Arabic translation made between 862 and 866 AD, preserved at the Library of Leiden University, the Netherlands. 

His most striking invention, in my eyes, is his steam engine, which I already developed in a separate post, A steam engine in antiquity. 

Another of his inventions is a coin-operated dispenser for Holy Water in Egyptian temples. Worshippers who visited the temple needed this water for their ritual washing. Dropping a coin into the slot of the dispenser would set a chain reaction into motion. The weight of the coin would tilt a metal lever which would open a valve through which the water flowed into the cup held by the worshiper. As the coin slipped off the lever, the valve was closed. This invention eventually led to the modern vending machine. 

Hero took his ingenuity one step further when he conceived a series of mechanisms for the Greek theater. He orchestrated a mechanical puppet show using a system of ropes, knots, and simple machines operated by a rotating cylindrical cogwheel. To add the sound of thunder, he used metal balls released at timed intervals onto a hidden drum. 

Another marvel Hero described in detail is the automatic temple door opener (see: Automatic doors, a 2,000-year-old invention), another way for the priests to collect money. 

He also invented the first wind-powered organ using a small wind wheel, probably not unlike the windmills used by the early modern colonists in Australia and the American Far West. The wind wheel powered a piston and forced air through the organ pipes creating sounds resembling a flute.

This mechanism includes the ‘hydraulis,’ which first appeared in Alexandria also, said to have been built by Ctesibius. It was operated by compressed air channeled through a container of water to equalize the pressure. A row of pipes of different lengths produced the sound. More control was acquired with the keyboard-wind instrument as replicated at the Museum of Dion, Greece (see: Close encounter with an ancient Water-Organ). 

I’d like to pick out one more of Hero's inventions from a list that may have counted up to 80, the syringe. The device is much larger than the one we know today since its purpose was entirely different. It was used to control the delivery of air or fluid with precision. Yet the principle of the antique version is the same: the plunger forced the liquid or air out in a controllable quantity. Something to remember next time we get an injection!

We will never know if the concept of creating a center of knowledge in Alexandria was Alexander’s idea or a later addition by Ptolemy. In my opinion, the concept was too vast for Ptolemy while it would perfectly fit Alexander’s thrive to melt East and West together as initiated at the Susa Wedding. 

We cannot imagine the impact of the Museum of Alexandria and its Library on the world’s history. Philosophers, mathematicians, botanists, writers, poets, historians, physicists, anatomists, astrologists, investors, and engineers from all over the then-known world would mingle and exchange their scholarship and wisdom. No other city in the world has ever reunited so many bright minds, not even in the Renaissance. Today’s digital world is the first to come close to attaining this level of universality.

Remembering Alexander’s birthday

We can be certain that Alexander never expected a hoard of tetradrachms with his effigy to be found and cherished nearly 2,500 years after his death. If that is not a worthy birthday gift, what is? 

This find dates from 2017, when a farmer recovered the coins from his land near Batman, on the confluence of the Tigris River and the Batman River in southeastern Turkey. The coins were all Alexander tetradrachms minted in the period between 332 and 322 BC. 

The coins fell into the hands of a Turkish collector, who said the hoard was complete, although no container was recorded. Since then, all the coins have been sold and disappeared from the radar. This means we only have the collector’s word for the information that has transpired. 

The coins were minted in several of the 25 known locations, such as Amphipolis, Aradus (Syria), Side, Sidon, and to a larger extent (one-third) in Babylonia. 

The Amphipolis mint was very active during the regency of Antipater, although the silver did not originate from local mines. The majority of the precious metal came from looting, and by far the largest amounts were collected by Alexander from the Achaemenid Treasuries in Babylon, Persepolis, Pasargadae, and Ecbatana (see: Harpalos’ mismanagement or is it Alexander’s?). We will remember that the king borrowed money when he started his invasion of Asia and took the bullion from the cities as he conquered them. 

The Batman hoard may have belonged to one of the Greek and/or Balkan mercenaries Alexander disbanded in late 325 or early 324 BC, or to one of his Macedonian veterans he sent home after the mutiny at Opis in 324 BC. This last group of 10,000 veterans, led by Craterus, was moving slowly through Cilicia when the news of Alexander’s death reached them. In antiquity, the Batman region was on the border between the satrapies of Armenia and Mesopotamia, not far from Cilicia. For that reason, it makes sense to link the hoard to the demobilized soldiers commanded by Craterus. 

It is important to realize that the Alexander coins were minted according to the standard Attic drachma of 4.3 grams. It has been estimated that between 333 and 290 BC, approximately 60 million tetradrachms were produced (see: A few words about Alexander mints and coins). More importantly, every soldier, veteran, and foreigner was totally familiar with Alexander’s picture and trusted the value of the coin bearing his image. For a long time, coins with Alexander's image kept circulating because his veteran soldiers were used to receiving their pay in tetradrachms!  

It remains questionable whether or how many of the 60,000,000 tetradrachms will ever be found. As the coins keep surfacing, we have to thank Alexander for his long-lasting legacy. By wishing him “Many Happy Returns,” we truly pay tribute to the timeless legacy he has left us. 

Not all Seven Wonders of the World are the same

We like to believe that the list of the Seven Wonders of the World in antiquity was well-established, but that is not entirely correct. 

In the 1^st century BC, Diodorus mentions them by name: the Great Pyramid of Giza, the Hanging Gardens of Babylon, the statue of Zeus in Olympia, the Temple of Artemis in Ephesos, the Mausoleum of Halicarnassus, the Colossus of Rhodes, and the Lighthouse of Alexandria. This is the list we follow nowadays, but the importance of each monument has been subject to personal taste and appreciation of its time. 

Well before Diodorus, many writers had their opinions on the matter. The oldest known is, for instance, Herodotus who, in the 5^th century BC does not mention the Hanging Gardens of Babylon but provides a very detailed description of the Walls of Babylon built with baked bricks cemented together with bitumen. The ramparts were 72 kilometers long, 10 meters thick, and 22 meters high! A striking feature is that the top of the wall was wide enough for two four-horse chariots to pass each other. The intermittent towers were 27 meters high. 

Callimachus of Cyrene, who lived in the 3^rd century BC, chose to include the Ishtar Gate of Babylon – a marvel that has been reconstructed inside the Pergamon Museum in Berlin (see: A mental reconstruction of Alexander’s triumphal march into Babylon). 

Philo of Byzantium in 225 BC lists the Walls of Babylon, but not the Lighthouse of Alexandria, which had not been built yet. He said he had actually seen the Hanging Gardens but omitted to situate them in Babylon. Their existence remains questionable, and there still is an unconfirmed theory that these gardens were in Nineveh. They were described as vaulted terraces, raised one above another, and resting upon cube-shaped pillars. These were hollow and filled with earth to allow trees of the largest size to be planted. The pillars, the vaults, and the terraces were constructed of baked brick and bitumen. The Gardens were initiated by King Nebuchadnezzar II around 575 BC. Philo tells of the Statue of Zeus by Phidias in Olympia, the bronze Colossus of Rhodes featuring Helios (the Sun), and the Temple of Artemis in Ephesos. He further includes the Tomb of King Mausolos in Halicarnassus, and the Pyramids of the Giza plateau, not singling out the Great Pyramid. 

Antipater of Sidon, who lived in the 2^nd/1^st century BC writes that he laid eyes on the ‘walls of lofty Babylon on which is a road for chariots’, and the Hanging Gardens; the statue of Zeus in Olympia, the Colossus of the Sun in Rhodes, the huge achievement of the high pyramids in Giza, the vast tomb of Mausolos at Halicarnassus; and the Temple of Artemis in Ephesos saying ‘that [as] it mounted to the clouds those other marvels lost their brilliancy’. 

Strabo, in the 1st century BC, gives by far the most detailed description of the Seven Wonders. 

The Great Pyramid of Giza in Egypt, the oldest and only wonder that still exists, was erected around 2560 BC. It is the largest of the three Pyramids at Giza, which are all equally important, as stated by Philo of Byzantium. The proportions of the Great Pyramid are colossal. The original height from the base to the peak was about 147 meters. The length of each side at the base averaged around 230 meters. The theories about its construction and function are widespread and are by no means conclusive. 

The statue of Zeus in Olympia stood inside the Temple of Zeus. The large sitting Zeus was made of ivory and gold by Phidias in 436 BC. Although he was seated, Zeus stood 12.4 meters high, meaning that his head nearly touched the ceiling. Nothing much of the temple remains, but its impressive East and West pediments are exhibited in full glory at the local museum (see: Olympia, in the footsteps of Pausanias). 

The first Temple of Artemis in Ephesus goes back to the 7^th century BC. After its destruction, it was completely rebuilt to an unheard scale of 115 x 55 meters, i.e., larger than the Parthenon in Athens. The Artemis venerated in this temple is represented with many breasts, and is clearly not of Greek origin but imported from the East (see: Alexander’s presence in Ephesus). Nothing remains today to prove its grandeur and glory.

The Mausoleum of Halicarnassus (see: Halicarnassus, capital of Caria) from about 350 BC was a rectangular monument measuring 40 x 30 meters, and about 45 meters high. It was decorated with scenes from Greek mythology, such as the battle of the Centaurs with the Lapiths and fighting Amazons, although scholars disagree on their precise position. It is certain, however, that the statues of King Mausolos and his wife/sister Artemesia riding in a four-horse chariot, now at the British Museum, stood at the very top of the Mausoleum. The tomb survived in pretty good condition for many years despite recurrent earthquakes, but the final blow happened in 1494 when the Knights of St John of Rhodes invaded the area and reused the stones of the Mausoleum to build their castle. Remnants are still visible to modern visitors on the walls of Bodrum Castle. 

The Colossus of Helios in Rhodes, the work of Chares of Lindos, was completed in 282 BC. It stood near the entrance of the harbor, although the exact location is unknown. The Colossus wore a crown of sun rays – hence its name, Colossus of Helios - and held up a torch. It was made of bronze and rested on a marble pedestal. With a height of 33 meters, it is considered the tallest bronze from antiquity. It was the shortest-lived ancient wonder that disappeared 60 years after its construction due to a severe earthquake. Its legend lives on, though. 

The Lighthouse or Pharos of Alexandria was the last wonder added to the list of seven, replacing the Walls of Babylon. It was conceived in three stages: a square stone base, an octagonal middle section, and a cylindrical shape at the top. Inside, a fire would guide the seafarers into the harbor of Alexandria. By day, they were led by the smoke, and at night by its bright light (see: Alexandria’s past futures). The Lighthouse stood over 100 meters tall, and its light could be seen 50-60 kilometers out at sea. Its construction was completed between 300 and 280 BC during the reigns of Ptolemy I Soter and his son, Ptolemy II Philadelphus.  

The ancient historians of Alexander the Great have spent very little ink on these Seven Wonders – or the texts simply have not reached us. The Temple of Ephesos, which was burnt down the night Alexander was born, was still under construction at the time of his visit. But the king must have witnessed the grand Mausoleum of Halicarnassus and the main features of Babylon, such as its Walls, the Ishtar Gate (which he used to enter the city), and the Gardens if they were indeed part of the Royal Palace. Strangely enough, Giza and its Pyramids are absent from all documents, as if they never existed!

Alexander’s Oriental Afterlife

This is the title of one of the many intriguing chapters in Robbert Bosschart’s book “All Alexander’s Women”. Beyond the widespread descriptions of Alexander’s life in our Western literature, the author hunted for Eastern sources. There are two key figures to consider, Ferdowsi and Nizami (see: Timeline of Main Arabic/ Persian Sources writing about Alexander). 

Ferdowsi is a Persian poet from the 10^th century who is still very much revered in Iran today, famous for his Shah-Nama, one of the longest epic poems in the world. It tells the (partially mythical) history of the Persian Empire from its creation until the end of the Sassanid rule in the 7^th century. 

The other prominent figure is Nizami, known as the greatest romantic poet in Persian literature. He lived in the 12^th century and described Alexander as a philosopher king and sage. 

It is not surprising that the Persians looked at Alexander from a very different angle as highlighted by R. Bosschart. Here are a few such examples, excerpts from his book: 

The vast popularity attained by the Alexander Romance over the centuries means that thousands of local storytellers have entertained millions of listeners in countless places with a marvelous or terrifying Alexander, made to measure for the taste of the audience.

But their tales were based on a very limited number of source texts. That is, whatever version of the Life and Deeds they might have heard or read, plus some (snippets of) local literature. For example, the 170 fake Alexander letters that circulated in Egypt from Ptolemaic times; or, in Persia, one of the contradictory Alexanders described in Ferdowsi’s Shah-Nama.

By the time this oral folklore became fixed in writing (a process that took obscure propaganda hacks and famous poets quite some centuries), an astonishing variety of Alexanders were living a fascinating afterlife. Most of them, just as an entertaining or educational sample of literary fantasy; but at least in two cases, with a profound social-political significance.

I am referring to the way in which the storytellers of Egypt and Persia appeased the bad conscience of their patriotic audience over the fact that their nation, with its ages-old, proud civilization, had submitted so meekly or even zealously to that young barbarian Alexander. Their solution was simple: they converted him to a ‘hidden’ son of a respectively Egyptian or Persian monarch, so that he could be welcomed back in ‘his true homeland’ as a liberator with full birthright to the throne.

…

The marriage of the daughter of Persia’s previous king to Alexander is a historical fact. During their negotiations after his first defeat, Darius III tells Alexander he can marry «one of my daughters». Years later, Alexander moreover receives the public approval of queen-mother Sisygambis to marry her granddaughter, the princess Barsine/Stateira.

But in his literary afterlife, the bride always is another princess: the insignificant Roxane, in the multiple versions based on the pseudo-Kallisthenes; or the magnificent, ‘divine’ Buran-dokht in a Persian tradition. However, in all these fantasied romances without exception, the reason why he marries her is the plea of the routed king Darius, who, with his dying breath, asks him to do so.

Only in the Persian version, Darius/Darab adds another petition to his deathbed plea. In Ferdowsi’s Shah-Nama, the routed king whispers in Alexander’s ear: «…Ask for my daughter’s hand in marriage; look after my children, my family, and my veiled wise women».

Who or what these wise women would be —so important that the High King in his last words before his death desperately wants to make sure they will be respected by the future ruler—, Ferdowsi sees no need to explain: he is sure that the (Persian) audience will understand.

This signifies two things. One: that wise women in the age of the Achaemenid empire were highly considered, and their rights were deemed worthy of the maximum protection. And two: as this oral tradition has been created to justify, to the eyes of a Persian audience, events in Alexander’s deeds which they recognized but needed to get explained, it follows that they knew that Alexander had wise Persian women at his side, and respected women’s rights. After all, such national sagas like the Shah-Nama and the Darab-Nama were intended as a reminder so that the Persians would not forget their glorious past.

… we are presented with an Oriental legend. Or rather, an embroidered version of a historic fact known to every Persian in the Achaemenid empire — and to many Jews, who revered Cyrus the Great because he had freed them from slavery in Babylon and sent them home to rebuild their temple in Jerusalem.

The fact is that in 530 BC Cyrus went to war against queen Tomyris of the Massagetai — and lost.

…

Tomyris sends a herald to Cyrus with her message: «Stop this war effort, because you cannot know if in the end it will do you any good. Be content to rule in peace over your own kingdom, and let me reign in mine. But of course, you will refuse my advice».

Cyrus indeed refuses to listen to her wise words, attacks – and dies on the battlefield. Now, it is a well-known theme that Alexander always tries to (and succeeds in) surpassing the feats of Cyrus. So here the Jews —who maintained good relations with Alexander throughout his reign, acting as loyal subjects— award him another victory: Alexander comes out a winner where Cyrus failed.

This is the beginning of a literary tradition – later represented so brilliantly by Nizami’s Iqbal-Nama— that describes Alexander as a philosopher king, Seeker of Knowledge, a sage whose only real aim is to learn wisdom.

...

Persia’s historical memory, as explained by the saga “Darab-Nama”, also remembers Alexander’s decision to promote mass-marriages for the better integration of conquerors and conquered into one realm. This is how the story in this popular saga was told to audiences all over Persia: 

Alexander and his army happen upon an island of women, and thousands of these invade the camp «searching for men». Alexander first suspects that they may be hostile, but soon understands they only want to make love —and then fears that his own men will “go berserk”, causing even worse problems. So he allows his wise chancellor –whose name is given as Plato— to apply a miracle-working solution.

Alexander and his wise chancellor Plato receive queen Sabaterah.

She reigns over an island where only women live, who all want

sex with men. Plato will ensure that they become legal spouses.

(Miniature from a 1720 AD manuscript of the Darab-Nama)

[Graciously shared by Robbert Bosschart]

Plato calls upon the women and asks them: «By the will of God, and so be all the Angels your witnesses, will you give yourselves in legal union to the men that will enter your city?» They agree. The storyteller concludes: «When the women were trying to seduce the men, it was the work of the Devil; but as soon as they were conveniently and legally married, it became God’s work, and Alexander could no longer be held responsible for any problems arising of their arrival».

Clearly, this is a remembrance of the mass-marriages (in reality, the legalization of de facto marriages) that Alexander organised in parallel with his double wedding at Susa in 324 BC. Out of his own purse, as Arrian reports in VII, 4, 8, he paid dowries for the Persian and other Oriental women who had taken up with his officers and soldiers, so they could be legally married. The list totalled some 10,000 dowries, and the classical sources say that Alexander disbursed over 10,000 talents of silver for them; an amount equivalent to 150 million dollars of today. It is understandable that these marriages, converting thousands of concubines into legal wives, left an indelible memory among the Persians.

Just as important was Alexander’s pledge that he would care for their offspring. Arrian notes in passing that he promised his veterans that their children from Oriental partners “will be educated as Macedonians”. But Diodoros tells more: he registers (in his Book XVII, 110, 3) that Alexander has set up a specific fund and appointed the necessary teachers to ensure that the 10,000 children his men have had with “women who were taken in war” will be educated “as is the right of free men”.

In Book XVIII, Diodoros adds that Alexander had decided to apply his integration policy on a much broader scale: «…he intended to establish cities and to transplant populations from Asia to Europe and in the opposite direction from Europe to Asia, in order to bring the largest continents to common unity and to friendly kinship by means of intermarriages and family ties».

Alexander’s intermarriage policy found lasting approval in Persia, as shown by the positive comment in the Darab-Nama on the “miraculous solution” devised by Plato.

For over a thousand years, Persian audiences have been listening again and again to this story in theaters, bazaars, harems and taverns. They must have agreed: after all, no storyteller makes a living by irritating his public.

Automatic doors, a 2,000-year-old invention

Several years ago, I happened to visit the plantation of former President Thomas Jefferson in Monticello, Virginia, USA. His estate which was completed in 1809 boosted on having a set of automatic doors inside the parlor. I found this a fascinating feature since I assumed this kind of automation was only born in the second half of the 20^th century. Well, I was wrong. 

Hero, a Greek engineer and mathematician from the 1^st century AD is the oldest known - or documented - inventor of the automatic door. The working principle is simple and must have amazed those who witnessed how the temple doors would open ‘spontaneously’ after the prayers of the priest.

We keep forgetting the huge amount of knowledge that was circulating in antiquity. Most of the great minds performed in many fields. They were philosophers, astronomers, mathematicians, architects, engineers, geographers, poets, etc. (see: Greek philosophers Alexander knew).

What a wondrous world!

The roaring times of the Antigonid dynasty

The Wars of the Diadochi broke out after Alexander’s death in 323 BC and his huge Empire went to “the strongest” as he may have intended to say on his deathbed in Babylon. However, it did not go to one single ruler as none of his generals had his vision or charisma. 

After endless battles, intermarriages, and lots of intrigues, Alexander’s generals eliminated each other and, in the end, started four distinct dynasties. Ptolemy initiated the Ptolemaic dynasty in Egypt, and Seleucos the Seleucid dynasty in Asia. Cassander, the son of Antipater, founded the Antipatrid dynasty (the ancient Kingdom of Macedonia). In 306 BC, Antigonus Monophthalmus (the One-Eyed) declared himself and his son Demetrios kings. By doing so, the Antigonid dynasty replaced the Antipatrid dynasty. 

Antigonus may well have served under Philip II and lost an eye during the Siege of Perinthus in 340 BC. He later joined Alexander on his Persian campaign and was promoted to satrap of Phrygia in 334 BC. His main duty was to maintain Alexander’s line of communication and supply. As a result of the Partition of Babylon following Alexander’s death, he also received Pamphylia and Lycia. 

During the Wars of the Diadochi, Antigonus picked up momentum and managed to rule over all of Asia Minor, Greece, Syria, Phoenicia, and northern Mesopotamia. Fearing his increasing power, Seleucos, Ptolemy, Lysimachos, and Cassander joined forces against him. Antigonus was defeated and killed at the Battle of Ipsus in 301 BC after which his realm was split between Lysimachos and Seleucos. 

However, Antigonus’ son Demetrios Poliorcetes, by now having earned his stripes as Besieger survived said battle and took control of Macedonia in 294 BC. Cassander died in 297 BC without a successor as his sons had eliminated each other, paving the way for Demetrios to become King of Macedonia. Not for long because in 288 BC he was driven out by Pyrrhus and Lysimachos, and died as a prisoner of Seleucos. 

It was not until 277 BC that Demetrios’ son, Antigonus II Gonatas, regained the title of King of Macedonia. He ruled till about 239 BC, to be succeeded by Demetrios II Aetolicus, followed by Antigonus III Doson ten years later. 

Meanwhile, Rome became the rising power in the eastern Mediterranean, and soon the first conflicts with Antigonid Macedonia led by King Philip V (221-179 BC) erupted. His successor, Perseus, put up a fierce resistance against the expanding Roman Empire that coveted Macedonia’s wealth. The Romans conquered Antigonid Macedonia in 168 BC at the Battle of Pydna, turning Alexander’s homeland into a mere Roman Province. 

Although very eventful, the Antigonid dynasty was short-lived and lasted less than 150 years. 

Macedonia’s grand palaces of Aegae, Pella, Bylazora, and Dimitrias were thoroughly looted, and the houses of the wealthy Macedonians were plundered. Statues, paintings, jewelry, and other wonderful, precious artifacts from Greece and Asia were up for grabs. Roman generals and common soldiers alike took as much as they could carry. Only the gods know what happened to the collection of Macedonia’s precious libraries.

Surprising city of Tripolis in Turkey

Tripolis can be found some 20 kilometers from the famous site of Pamukkale and the ancient city of Hierapolis. Its name meaning three cities is due to its location, i.e., at the crossroads of Phrygia, Lydia, and Caria, on the northern bank of the Meander River. From here, it was a convenient hub to reach Sardes, Philadelphia (modern Alaşehir), and Laodicea. 

Although Tripolis existed in Hellenistic times, it reached its peak in the 2^nd century AD as testified by the remains we find here today. 

The city could be entered by two gates, the Gate of Hierapolis on the southern side and the Gate of Philadelphia at the western end.

[Picture from Female Fearless Travels]

Excavations have exposed a straight colonnaded street of ten meters wide and 450 meters long that runs east-west through the city. It was paved with travertine slabs. At the intersection of the main streets, a Nymphaeum was discovered. This Orpheus Fountain rested on a marble floor, and its walls were covered with onyx and white marble. The water came from a cistern east of the street. 

The colonnaded street is the most prominent element in Tripolis and is for now the main attraction. Pending further digs, several monuments from the 2^nd century AD have been identified, such as two Agoras, one of which borders the northern side of the street, and two Baths, the Great Thermae near the western entrance to the city, and the Theater Thermae close to the theater. The theater is estimated to seat 8,000 people. Also, the Stadium could be located just outside the city walls and measures 256x66 meters. The Bouleuterion of 64x44 meters stands in the center of Tripolis, and only part of its walls are visible. 

[Orpheus Fountain from Turkish Archeo News]

It is remarkable, however, to discover an indoor bazaar in excellent condition since it remained buried for centuries. This structure is a unique example so far in the Mediterranean. 

The fate of Tripolis was sealed after repeated earthquakes, the most severe one happening in 494 AD.  

A visit to Tripolis sounds rather inviting. The colonnaded street is very promising, but sadly little is known of the city’s role in history despite its early origin dating to the 4^th millennium BC.

With a population of nearly 20,000 in the 2^nd century AD, I assume an emperor like Hadrian would be mentioned as he stayed in nearby Hierapolis in 129 AD. This also applies to Caracalla in 215 AD. I would not be surprised if during Hellenistic times members of the Seleucid dynasty spent time in Tripolis. Apparently, nothing of the kind has transpired from the excavations yet. It is like visiting a skeleton without a soul …

Plato and Atlantis

Plato wrote 35 Dialogues but two of his late Dialogues, “Timaeus” and “Critias”, are quite unique as they relate the history of Egypt to around 9,000 years before his time! That is where and when Atlantis is mentioned. Timaeus was a philosopher and astronomer from Locris in southern Italy, and Critias was an Athenian politician. 

Atlantis is, was, and will be very controversial. Yet, Plato’s tale is all we have to go by. As in every story or legend, there is always a base for some truth. To bring the Athenians in contact with Atlantis sounds far searched, but there is hope for the skeptics. 

In February 2022, Sotirios Sofias of the National Technical University of Athens published a very revealing study on the matter under the title “Atlantis: A real continent and not fiction according to the dialogues Timaeus and Critias of Plato”, which I will try to summarize hereafter. The author has analyzed the original ancient Greek text as recorded by Plato to match it with Google Earth's screenshots - with surprising results. Please remember that Plato was a pupil of Socrates (see: Plato, more than a philosopher). 

Critias, during a meeting with Socrates, Timaeus, and Hermocrates (general of Syracuse), describes the visit of Solon of Athens to Egyptian priests around 600 BC. On this occasion, the priests honored Athens in all its glory including the city’s victory over the people of Atlantis. The Atlanteans, they continued, lived on an island beyond the Pillars of Heracles and had conquered all the islands of the Atlantic Ocean and many others in the Mediterranean Sea, including Egypt. Yet, all the countries revolted against the aggressive Atlanteans, led by the Athenians, who were victorious. Atlantis suddenly disappeared after a terrible natural catastrophe. 

Modern technology shed a new perspective on Atlantis when in 2009 Google Earth revealed the outlines of a submerged formation about 600 kilometers northwest of the Canary Islands. The main feature appears as a manmade grid, which matches Solon’s “square” or “plain”,  the capital Atlantis as recorded by Plato.

Studying these images, Sotirios Sofias found that all the measurements of Atlantis noted by Plato are consistent with those visible in the Google Earth pictures. The stunning underwater square, whose sides are 140 kilometers long, is divided by channels following a perfectly recognizable Hippodamian plan. The water from the surrounding mountains flowed through the city’s canals to serve its needs in fresh water and as a transportation system for the Atlanteans. 

This city and the island of Atlantis disappeared after a severe cataclysm, destroying Athens at the same time, and the city's glory was forgotten. The large island of Atlantis sank to the bottom of the Atlantic Ocean, five kilometers deep! 

After an in-depth study of Plato’s text, Sotirios Sofias established that Atlantis was sitting on a super volcano similar to Yellowstone National Park in the US including the same kind of hot springs and therapeutic sources. Both sites have more in common than one would imagine as Critias describes a landscape resembling modern Yellowstone's beauty. He praises the fertile soil of Atlantis with its abundance of trees, fruit plants, and the variety of tamed and wild animals that populated the island! The island was also known for its minerals like gold, silver, copper, tin, etc. The inhabitants of Atlantis did not know they lived on top of a volcano, very much as the people of Pompeii did not know that the mountain on their horizon was a volcano.

The global cataclysm mentioned by Critias was, in fact, the eruption of this supervolcano in combination with the violent rotation of the earth's axis. Plato attributes this event to a meteorite or comet (which he calls Phaethon) that hit the earth. It caused the destruction of Atlantis, Athens, and all the nearby coastal cities and islands. The Egyptian priests told Solon that their country was saved thanks to the Nile. This is how the ancient texts of Atlantis were spared for 9000 years! Solon’s notes on Atlantis survived and were passed on to Plato via his uncle Critias. 

Plato clearly mentioned that the city was protected on the North side by high mountains. Google Earth has indeed located three submerged mountains of 4,000-4,500 meters that have moved 75 degrees counter-clockwise after these violent forces of nature occurred, erasing the island from view and memory. 

Another controversial subject is the shape and size of Atlantis. Solon mentioned that the island was narrow and extended from the coast of Spain to the present-day Antilles. It included islands like the Azores, which are the mountain peaks of the submerged Atlantis mentioned above. Critias provides details stating that the island's eastern end was opposite the Pillars of Heracles (Gibraltar), at Gadiriki (modern Cadis in Spain).  At the opposite end, it almost automatically takes us to the Lesser and Greater Caribbean Antilles and the Americas. 

Based on the measurements of Critias as compared to the geographic layout of Google Earth, Atlantis had an elongated shape like a banana. It was 4,500 kilometers long and 760 kilometers wide in its center. The western end of the island was only 1,000 kilometers away from the coast of South America, i.e., the distance an ancient ship could cover in one week. 

This reminds me of the news that made headlines several years ago about artifacts of Phoenician origin discovered in South America. Highly improbable, it was thought, and the wildest speculations followed! Presently, in light of the shape and size of Atlantis, the find is not outlandish at all! Sailing from the Mediterranean across the Atlantic Ocean along the south coast of Atlantis was extremely convenient as the ships could stop at so many ports on their way! When Atlantis disappeared, this communication route vanished and all memory of this once so-powerful kingdom was erased at the same time. 

Now there is the story of Atlantis everybody is familiar with a series of successive circles around a central island. Based on Critias’ account, this central island had a diameter of 1,000 meters. It was surrounded by two circles of land and three of water. This is the location of the Palace of Atlantis. The ditch around the central island was connected with a 9,500-meter-long canal to the sea. The total diameter of these combined circles was 5,000 meters! Hard to imagine! 

The Palace of Atlantis was the residence of the Major King. Critias noted that it was of astonishing size: 200 meters wide and 200 meters long, standing 100 meters tall. It was bigger than St Peter’s Basilica in Rome. Atlantis was divided into ten kingdoms, each with its own king, subordinate to the Major King, the direct descendant of Atlas, son of Poseidon, and founder of Atlantis. Solon said that the god was held in high esteem by the Atlanteans, as quoted by Critias: “They placed golden statues, the god (Poseidon) to be upright in his chariot, holding the reins of six winged horses, and this complex was so tall that it almost touched the top of the roof of the temple. Around him, seated on dolphins, there were a hundred Nereids along with innumerous other statues around, dedicated to exceptional individuals.” 

All the above takes me to Alexander, as I so often speculate about his knowledge of the world when he set out to conquer Asia. He, and his selected circle of friends, had been tutored by Aristotle, a pupil of Plato. In this light, history deserves to be rewritten. We should be aware that besides Alexander, all of his Companions and later generals and kings in their own right, were aware of a world much larger than we generally assume!
