The Bell Beaker People identified by their distinctive pottery existed from around 2800 BC until 1800 BC. They occupied large areas of Iberia, Central Europe and the British Isles as well as some of the western Mediterranean islands. Associated with them are the Wessex people divided into Wessex I and Wessex II, who are found in western Europe and southern Britain, the latter, dated to 1650-1400, were involved with the construction of the later stages of Stonehenge.
Uwe Topper associates the beginning of metallurgy with the Bell-Beaker People(e).
Melville Nicholls and others(b) have linked Atlantis with the Bell Beaker culture, identifying a location near Gibraltar as the site of Atlantis. He published his views in Children of the Sea God, a 2013 Kindle ebook(a)and a second ebook, The Real and Imaginary Atlantis generally reprising the first, later the same year!*Further comment from Nicholls can be found on an internet forum(f).*
The Beaker People are also claimed to have crossed the Atlantic, where they have been linked to the Adena culture of North America. A leading exponent of this theory is undoubtedly Jay S. Wakefield, co-author of How the SunGod reached America . He has reprised his views in a 2018 paper on the Diffusion & Migration website(c) . Others have expanded on his concepts(d).
