    Joining The Dots

    I have now published my new book, Joining The Dots, which offers a fresh look at the Atlantis mystery. I have addressed the critical questions of when, where and who, using Plato’s own words, tempered with some critical thinking and a modicum of common sense.Read More »

Seafaring and Atlantis

Seafaring and Atlantis are inextricably linked. Critias 117d anachronistically refers to the shipyards of Atlantis being full of triremes, which were not developed until the 7th century BC, long after the demise of Atlantis. However, the term ‘trireme’ was probably employed by Plato in order to make his narrative more relevant to his audience. He credits the Atlantean navy of 1200 ships, which seems like a borrowing and rounding of either the Achaean fleet (1186) in Homer’s Iliad or that of the Persian invaders (1207).

Seldom referred to, but perhaps even more interesting is to be found earlier in Critias 113e which reads “for at that time neither ships nor sailing were as yet in existence” in reference to the origins of Atlantis. However, we are given little information to bridge the time up to its development as a major trading entity. It is reasonable to assume a gap of several thousand years.

Recent studies(a) have suggested that primitive seafaring took place in the Mediterranean thousands of years earlier than originally thought and may even have been engaged in by Homo Erectus and Neanderthals in the form of island hopping and coast hugging, the latter continuing into historical times.

Plato’s describes an advanced maritime trading nation with a powerful naval capacity. How much was part of the original story brought from Egypt by Solon or if it was in any way embellished by Plato is unclear. The earliest known trading empire is that of the Minoans which began in the 3rd millennium BC and has led to many identifying them with the Atlanteans. However, there are very many other details in Plato’s narrative that seriously conflict with this hypothesis.



Triremes were ancient warships ships that had three banks of oars with up to 180 rowers and armed with a bronze-sheathed ram on the prow(f). Although we generally associate triremes with the ancient Greeks, they are thought by many to have been originally developed by the Phoenicians, and of interest to us, is the fact they are described by Plato as being part of the Atlantean Navy.

However, the existence of triremes is completely incompatible with a 9600 BC date for the destruction of Atlantis as triremes were only developed around 9,000 years later. Triremes were built of lightwoods and were designed for a day’s travel at a time (50-60 miles) as onboard facilities were quite limited and could be easily beached at night. However, claims that these 45/50-ton vessels could be carried by as few as 140 men(e) is difficult to accept.

Triremes were top-heavy and somewhat prone to toppling over in a violent storm and quite clearly were unsuitable for an ocean such as the Atlantic.  Consequently, they were considered to be fair-weather vessels and were not generally used in winter(c).

It is likely that Plato used the term trireme to make the story more relevant to his Athenian audience, by simply describing what was the state-of-the-art warship of his day.

In 1987 a fullscale copy of a trireme, Olympias, was launched(a). The ship was due to visit New York in 2012(b). A book describing the construction and trialling of the Olympias is also available(d).








Atlantean Navy

The Atlantean Navy consisted of 1,200 ships, according to Plato. Such a fleet would be totally unnecessary unless your potential enemies had a similar force. It is worth noting that that over 130 quotations from the Illiad and Odyssey have been identified in Plato’s writings, suggesting the possibility of him having adopted some of Homer’s nautical data. Homer records that the Achaean fleet consisted of  1,186 ships, a number that could be naturally rounded up to 1,200 – a coincidence?

Similarly, Herodotus records that the Persians had a fleet of 1,207 triremes at the Battle of Salamis (480 BC). It is a further remarkable coincidence that of all the military statistics recorded by Plato, the only number that is not an exact thousand, relates to the size of the Atlantean fleet. A number that is the rounded value of the Achaean fleet in the Trojan War and the Persian fleet which attacked Athens just 50 years before Plato was born. It is not improbable that 1,200 was used in this isolated instance as a  representation of the ultimate in naval power at that time! A website that reviews the classical sources relating to the Persian fleet in greater detail is available(c).

Since conventional archaeology identifies the Bronze Age Greeks and the Phoenicians in the Eastern Mediterranean as possessors of the earliest navies, the possibility of a naval force of such a great size 9600 BC is considered improbable if not completely impossible. Recent discoveries on Cyprus have provided evidence of primative seafaring in the region as early as 12,000 years ago. However, it appears that occasional travellers from Turkey and Syria who utilised crude stone tools arrived there in rather small boats. We are therefore forced to conclude that Plato’s reference to a powerful navy supporting an extensive merchant fleet is either a heavy embellishment of a real story regarding a prehistoric civilisation or an allusion to an actual Bronze Age thalassocracy.

An interesting series of illustrated articles(a) on ancient ships offers a useful background for the study of the Atlantean Navy.

Plato describes the Atlanteans as using triremes which is quite improbable as they were probably not developed until around the 7th century BC(b). It is more likely that Plato used the term trireme to make his narrative more relevant to his Greek audience.
