Diffusion is the anthropological term used to describe how similar customs, beliefs and artefact designs are spread between cultures through migration, invasion or trade. Diffusion is not just a ‘one-way street’ as history has shown that ideas have travelled in all directions, while in fact most ancient civilisations can be demonstrated to have absorbed cultural elements from a multiplicity of foreign societies. Today, globalisation has increased exponentially the variety of influences that all societies now experience. Not only is the number of these influences greater but the rate of increase is apparently accelerating. The ubiquity of Coca-Cola, T-shirts, Irish pubs, Japanese cameras, German cars, English language, Guinness, Chinese toys, ABBA, AK-47s etc., etc., etc., are indicative of the global reach of commercial ‘empires’ today. In older civilisations trade was more concerned with commodities such as metals, olive oil, wine, amber, obsidian, or timber, so the technologies involved in their production or exploitation were also exchanged.
The development of agriculture also saw techniques spread, which had to be modified to suit different climates, although recent studies indicate that agriculture started around the same time in a number of centres(I).
In the Fertile Crescent as far north as the Zagros Mountains and further north, on the steppes of Russia, horses were domesticated and apparently there also the use of chariots originated. A book by David W. Anthony also attributes the region as being the source of what is known as the Proto-Indo-European family of languages.
Societal concepts, religious or legal were no different as their geographical spread can also be tracked over time. Consider the different strands of the Abrahamic faiths, beginning with Judaism, which spawned Christianity and later was joined by Islam through Muhammad, who claimed to be a descendant of Abraham. Similarly, democracy has slowly evolved and spread over time and still has a long way to go.
Since early man left Africa, he has had ample time to settle all over our planet and exploit its resources, moving from being a hunter-gatherer to becoming a settled farmer, developing urban centres (city-states), then empires and the inevitable wars. Wars, then like today, led to the development of new technologies, chariots, longbows, and armour, to be copied and if possible improved upon, by each side.
My view is that initially, technology and techniques were freely exchanged between peoples, until gradually the idea of monopoly entered the human psyche, eventually leading to the paranoia and greed associated with the ownership of ‘intellectual property’ today. I would speculate that a freer and possibly gentler diffusion of ideas lasted until, at the earliest, the first millennium BC.
In 2014, the University of Connecticut published the result of studies that demonstrated that human technological innovation occurred intermittently throughout the Old World, rather than spreading from a single point of origin, as previously thought(j).
Egerton Sykes, a leading 20th-century Atlantologist, was a committed diffusionist, describing it as “the lifeblood of civilisation”(h).>Atlantisforschung has published a 1967 paper by Sykes supporting diffusionism with particular reference to pyramid building on both sides of the Atlantic(ad).<
>Andrew Cutler published a paper on cultural diffusion in August 2023 that should be studied by anyone interested in the subject. He discusses themes such as the Pleiades, Snakes, Finger Removal and Linguistics among others. He expresses the opinion that while many assume that such common features can be traced back to before the 100,000 BC Out of Africa migration, Cutler suggests a much later time circa 40,000-30,000 BC(ae).<
A more extreme view is the concept of ‘hyperdiffusion’, which is the idea that there was a single ‘mother culture’ that led to the development of all major civilisations. Ignatius Donnelly was a hyperdiffusionist, advocating Atlantis as the mother culture. His ‘heretical’ views were highlighted by the range of similarities between structures around the world in apparently unrelated cultures, which seem to greatly exceed what could be expected by mere coincidence alone. This is explored further in a recent illustrated article on the Malagabay website(v).
Similarly, James Churchward proposed his invention, Mu, as an alternative hyperdiffusion centre. Perhaps better known is the work of W. J. Perry who was convinced  that an archaic civilisation had begun in Egypt and gradually spread eastward through Asia and Polynesia, eventually reaching the Americas. Ben Urish published a paper(d) in 1986 that offers a critical overview of hyperdiffusion.
Konrad Kulczyk promotes a hyperdiffusionist theory that places his proto-civilisation, New Atlantis, just south of the Aral Sea(e).
Ivar Zapp proposes the existence of a global seafaring civilisation thousands of years before the Greeks, Egyptians or Sumerians(k) in an as-yet-unpublished book, Babel Deciphered.
Hyperdiffusion is clearly a seductive theory that has attracted the attention of researchers such as Richard Cassaro, who has produced an impressive collection of visual cultural similarities between ancient Egypt and pre-Columbian America(a). While the idea is not new, Cassaro’s images highlight the concept of diffusion very effectively, although he has, in my opinion, overinterpreted the evidence in order to support hyperdiffusion.
Cassaro published The Missing Link in 2016 in which he expands on the widespread distribution of what he refers to as the ‘godself icon’. Although he clearly demonstrates that the motif has an extensive geographical spread it is equally obvious that the appearance of the icon is spread over a vast period of time apparently coinciding with the emergence of civilisation in different places at very different times, which, in my view, is not fully compatible with the concept of hyperdiffusion, as I would have expected a ‘mother-culture’, if such existed, to have spread its global influence far more rapidly.
A comparable discovery has been made by Ozgür Baris Etli, who has drawn attention(o) to carved hands at Göbekli Tepe that have counterparts in many other parts of the world where hands meet at the navel are similarly depicted. I recently came across an image of(q) a megalithic statue in the Indonesian Bada Valley(u) showing its hands in a similar position. Also in Göbekli Tepe, we encounter what has become known as ‘the handbag of the gods’(y) which has been found depicted in many locations such as Turkey (Göbekli), Iraq (Assyria), Mesoamerica (Olmecs)(w), Egypt and New Zealand(x). These images are not only spread over thousands of miles but thousands of years.
However, Andrew Gough is the only researcher who seems to have come anywhere near to explaining the purpose of the ‘handbag’. In a lengthy article on his website, he explains how a British Museum guide confirmed that the bag was a pollen carrier(ac). This dovetailed with Gough’s view of his belief regarding the importance of the bee in ancient cultures.
Having mentioned Indonesia, I must draw your attention to a recent book by Dhani Irwanto, entitled Sundaland: Tracing the Cradle of Civilizations (1618), in which he makes a strong case for considering his native land as an ancient diffusionist centre, which experienced waves of emigration at the end of the Younger Dryas period that influenced the great civilisations of the Indus Valley, Egypt and Greece. Irwanto also claims that their cultural impact included the transference of the story of Atlantis from its original home in Sundaland.
Equally intriguing is the ‘Three Hares’ motif, found across Europe, the Middle East and as far as China(p) and now the subject of a book by Greeves, Andrew & Chapman. Another stylised symbol is that of the rosette found in the Mediterranean and spread as far as India(r)(s).
In a similar vein, Jim Allen has devoted chapter three of his latest book to outlining what he entitled Bolivia and the Sumerian Connection(b). Arguably even more impressive is the array of images presented by Allen(c) suggesting that the civilisations of America were greatly influenced by ancient cultures in both the East and the West. It is obvious that a number of artefacts can be developed independently, but at some point, the number of similar items produced by two separate cultures can exceed the number that can be reasonably put down to coincidence. The number of similarities presented by Allen alone clearly exceeds that threshold, demonstrating that the Americas were influenced by different sources, ruling out the Americas as the home of a mother culture.
>Similarly, Gary A. David proposed that Votan was a diffusionist deity with counterparts known by other names such as Kukulkan, Quetzalcoatl or Viracocha in the different American civilisations. However, he goes further placing Votan’s origins in the Old World suggesting that he may have been Phoenician or Hebrew, citing Adrian Gilbert and Andrew Collins in support of this(af).<
An extensive website managed by Erich Fred Legner offers a wide range of evidence to support the view that the Americas had been visited and settled by people from both Asia & Europe before Columbus(aa).
The whole subject of diffusion is wide-ranging and complex and well beyond my competence to do it justice in this short entry. However, for those interested in pursuing the subject further, I would like to recommend a 1997 paper(l) by David H. Kelley (1924-2011), available on Dale Drinnon’s website.
Egypt is frequently mentioned in this regard being seen as the influence behind Neolithic megalith building AND the pyramids of Central America, in spite of the fact that Newgrange was constructed before the Egyptian Pyramids and the New World pyramids were built thousands of years after those in Egypt. Atlantis is regularly suggested as another mother culture but without a single piece of evidence to support this speculative contention. For decades the idea that the pyramids of Egypt and those in the Americas were the consequence of diffusion from a common source, namely Atlantis situated in the Atlantic was heavily promoted. However, we can now more closely identify the pyramids of America with the step pyramids of China!
Consequently, for me, hyperdiffusion is not convincing. History has clearly shown that inventions have frequently been independently developed at the same time in different countries, while even in prehistoric times it has been demonstrated(f) that the evolution of stone tools took place as a result of the innovative abilities of local populations, addressing the same needs.
A word of warning; “recent research published in Nature by a team led by Tomos Proffitt at the University of Oxford shows that capuchin monkeys regularly produce sharp-edged flakes indistinguishable from those made by early hominins.”(t)
Even today technologies are developed independently throughout the world, but not in complete isolation, because of the instant worldwide communications available.
As a result of global marketing, in Ireland now we drive German, British and Japanese cars, use US computer technology and play with Chinese toys. However, being generous by nature, we gave the world the Irish pub, Riverdance and Guinness.
A two-part blog(m)(n) highlighting the many weaknesses in the concept of hyperdiffusion should be required reading for anyone interested in the subject.
Although Donnelly and his contemporaries, focused on the possibility of Old World influences in the New World, today, there is less of a Mediterranean-centred or Eurocentric approach to diffusionism. Instead, there is greater acceptance that the Americas have also had extensive cultural influences from Asia.
In March 2021, Hugh Newman published a paper drawing attention to the similarity of megalithic building techniques, using polygonal stones, in America, Asia, Europe and Africa. He goes further noting that “Peruvian relief carvings match those at Göbekli Tepe.” How much might be the result of coincidence is a matter of opinion.(ab) In January 2022, Marco M. Vigato published a new book, The Empires of Atlantis , in which he offers a hyperdiffusionist view of Atlantis. He “traces the course of Atlantean civilization through its three empires, as well as the colonies and outposts formed by its survivors in Egypt, Göbekli Tepe, India, Mesopotamia, the Mediterranean, and North and South America” and “reveals how the first Atlantean civilization lasted from 432,000 to 33,335 BCE, the second one from 21,142 to 10,961 BCE, and the third Atlantis civilization–the one celebrated by Plato–collapsed in 9600 BCE, after the Younger Dryas cataclysm.”(z).
