Diego Ratti is a financial consultant by profession and the author of two related books, Wall Street Watchman  and The Sky Watching Trader . However, his love of astronomy, archaeology and Lampedusa came together in the development of his website(b). On this small island of Lampedusa in the Strait of Sicily a ‘Stonehenge’ has been identified by Ratti and described in a well-illustrated paper and booklet(c).
In 2015, he published, in Italian, a book on the prehistory of Lampedusa, La preistoria di Lampedusa .
In a 2016 paper(i) he identified the remains of a prehistoric village on the island as providing “evidence for a late fifth millenium BC colonisation of Lampedusa island by people from Sicily, chronologically around the same time of the Malta early colonisation.” A year later he published another paper(j), La Preistoria di Lampedusa: nuove ipotesi ed interrogativi (The Prehistory of Lampedusa; New Hypotheses and Questions), unfortunately also in Italian only.
Around the same time, Ratti also discovered a “prehistoric underwater place of worship” off the eastern coast of the island(d), and later published a video of the site(e), describing it as a temple similar in layout to some of the Maltese temples.
In March 2021, Ratti published Atletenu , in which he places Atlantis in Egypt, with its capital located at Avaris, better known as the capital of the Hyksos. He identifies Atlas as “Shamshi-Shu I: the Amorite Prince of Ugarit who in 1646 BC led a coalition of Foreign Kings to conquer Egypt starting the XV Dynasty of the ‘Hyksos'”. The book is carefully constructed and well-illustrated, but has no index.
He questions a number of the English translations of the Greek text, offering his own where he deemed it appropriate. One such instance concerns ‘meizon‘, normally translated as ‘greater’ in Tim. 24e & Crit.108e, which Ratti insists should be read as between Libya and Asia, which Avaris clearly is. I pressed Ratti on this interpretation and, after further study, he responded with a more detailed explanation for his conclusion(g). This is best read in conjunction with the book.
However, although he appears to match a number of Plato’s details with the Nile Delta, there was not enough to convince me. Where are the mountains described by Plato with a series of superlatives? Tim 25a-b, describes Atlantean territory as including part of southern Italy, so where is the evidence for the Hyksos occupying any part of Italy? Where is the evidence that Athens fought with the Hyksos?
However, I must acknowledge the extensive amount of research that has gone into this book, which is available as a Kindle or paperback, excerpts from which can be read online(f)(h). It is certainly worth a look.

Claude Frédérick-Armand Schaeffer (1898-1982) was a French archaeologist who is probably best known for his work at the Ras Shamra site in Syria which he identified as the ancient port city of Ugarit. He worked on and wrote about the site from 1929 until his death.
Schaeffer enter the arena of catastrophism in 1948 when he declared that during the Bronze Age on at least five occasions widespread catastrophic destructions has taken place throughout the Middle East.
>Some chapters from his book, Stratigraphie Comparée et Chronologie de l’Asie Occidentale (III et II. Millénaires), have now been translated and available online(c).<
He attributed these events to seismic activity,which was perhaps related to the ‘seismic storm’ referred to by Stavros Papamarinopoulos in his paper, Plato and the seismic catastrophe in the 12th century BC Athens(b).
Plato recorded how the priests of Sais told Solon of a succession of catastrophes that befell the region, including earthquakes, inundations such as the Flood of Deucalion and the fall of Phaeton adding historical support for the theories of Schaeffer, Velikovsky and Gallant inter alia.
Schaeffer and Velikovsky exchanged correspondence(a).
