This conclusion is probably based on the existence of a location on the northeast coast of the island called Gadir. However, it must be kept in mind that Gadira or variants of it are frequently found in the Mediterranean region, usually at the site of former Phoenician settlements. However, north of Pantelleria are the Egadi Islands(c), another name evocative of Plato’s Gades.
Gades has been associated with Erytheia in the story of the Trials of Hercules, so if the Map Mistress website is correct in locating Erytheia(d) between Pantelleria and the Egadi Islands, it would confine all the ‘Trials’ in the Central and Eastern Mediterranean, consequently, locating the Pillars of Heracles somewhere in the latter region.
More recently, some authors have identified the Straits of Sicily as being the location of the Pillars of Heracles referred to by Plato in his tale of Atlantis. A land bridge between Sicily and Tunisia, including Pantelleria, has also been suggested, but this is unlikely according to bathymetric data.
A fortified Neolithic village has been unearthed on its west coast and ancient structures, known as ‘sesi’, similar to the nuraghi of Sardinia, are to be seen in the southeast. In 2005, jewellery in the style of the Egyptian Second Intermediate Period (1700-1550 BC) was discovered on the island. This would add to the opinion that Pantelleria was a major trading and cultural crossroads in ancient times.
Massimo Rapisarda has commented that “a good candidate to host a primordial civilization might have been the archipelago then existing in the Strait of Sicily, a natural maritime link between Tunisia and Italy, prized by the presence of an obsidian source at Pantelleria.”(f)
In August 2015, it was claimed(b) that a manufactured stone column was found on the Pantelleria Vecchia Bank, just north of the island of Pantelleria, in 40 metres of water. It is claimed that the area was an archipelago, if not actually connected to Sicily, before the last Ice Age ended around 7350 BC. The monolith was dated using shells extracted from it. It took no time before the discovery was linked by a number of sites with Plato’s Atlantis. While I believe that the area was part of the Atlantean domain, I am more inclined to date its expansionist intentions to a much later period, such as the 2nd millennium BC.
Gades is the Roman name of what is generally accepted as having been located at or near modern Cadiz in southern Spain. In his Critias Plato relates that the twin brother of Atlas, the first ruler of Atlantis, was named Gadeiros although known in Greek as Eumelos. It is assumed that he had his realm in the vicinity of Cadiz and had his capital named, Gadeira, after him.
However it has been pointed out that the Phoenicians who, before the time of Plato, possessed a port city in southwest Spain named Gadir meaning ‘enclosure’ or ‘fortress’ and was, over time, corrupted to Cadiz.
Until recently it was generally accepted, based on classical writers including the historian Livy, that the Phoenicians founded Gades around 1100 BC. Writers today such as Mark Woolmer have pointed out [1053.46] that the archaeological evidence suggests a more recent date, perhaps the middle of the 8th century BC.
However, a number of locations with similar sounding names are to be found in the Central and Western Mediterranean region, weakening the certainty normally associated with the more generally accepted identification of Gadeirus’ city with South-West Spain.
Another solution has recently been proposed by the late Michael Hübner, in which he offers the Souss-Massa plain of Southern Morocco as the location of Atlantis. On the Atlantic coast of the plain is the large town of Agadir, whose name is also probably derived from the word ‘gadir’ which means fort or enclosure in the local Tamazight language. It can also mean ‘sheep fold’, which may tie in with Plato’s use of ‘Eumelos’ as the Greek translation of Gadeiros means ‘rich in sheep’.
Alternative suggestions have been proposed, including one by Andis Kaulins(a), who is inclined to identify the islands of Egadi (Aegadian), off the west coast of Sicily, which is opposite today’s Tunis. Should this Egadi be the original Gades it would make sense of two of the suggested alternatives for the location of the Pillars of Heracles, either the Strait of Messina or the Strait of Sicily, where there is a Gadir on the island of Pantelleria(b). It would mean that Egadi would have been outside the Pillars of Heracles from either an Athenian or Egyptian perspective. Albert Nikas has pointed out the existence of a place in Malta called Il Ghadira, which has the largest sandy beach on the island!
More recently Jonathan Northcote has suggested that Gadeira may have been Ireland,*citing Strabo, who quoted Eratosthenes, who had noted that Gades is five days sailing from the ‘Sacred Promontory’. Wikipedia lists(d) eleven promontories stretching from Crimea to Wales that have been so named, but noting that these were only some of the locations given that designation. So he arbitrarily chose either of the two Portuguese Capes listed as the most likely starting point for a five-day journey to Ireland (Gadeira)!*
Stuart L. Harris has echoed this, employing linguistic gymnastics(c). He uses Felice Vinci‘s idea that Homeric Greek was in fact a form of Finnish and so Gadeira was Käde Eiran, meaning ‘Hand of Eira’, supposedly a variant of Éire (Ireland) and consequently Atlantis lay to the west of Ireland. Convoluted, is an understatement.
