Algonquian languages are not organized along at all similar lines as any language I know from Europe. At all. Definitely not anything Indo-European, and probably not any pre-Indo-European substrate languages of the Mediterranean.
If I was keen on proving the author's theory, I would start analyzing proto-Algonquian grammar and see if there is any solid, regular connection with linguistic substrata in Europe (Basque, Etruscan, pre-Greek, etc.). But it's pretty doubtful. I actually came to Algonquian grammar after having studied Latin, Greek, Etruscan, Osco-Umbrian etc. It's a pretty stark difference...Mediterranean languages are typically inflected, whereas Algonquian, like many American languages, is agglutinative.
To make a long story short, I wouldn't put a whole lot of stock in this hypothesis the author lays out.
The Talkers on the Canadian side of the Akwesasne have some of the same Euro-parallel information such as the Dardenelles ``stone canoe that can go upstream by itself.`` 99% of the Talkers` knowledge is not written down- just oral transmission from thousands of years ago. They will not speak to anyone who is not Nation. [cf Greek legends,- ]
A 30 year old book, America BC, postulated that the eastern tribes, particularly the Algonkian had been influenced by Celtic travellers from Europe of 300-100 BC. The author used Caesar’s descriptions of the vessels of the Celtic Brits in The Commentaries, large nulti deck vessels with sails and oars, much larger and more sea worthy than the Roman Triremes,that could have made the cross Atlantic voyages. Also the presence of furs in Celtic and Gaulish culture that,in retrospect, do not seem native to Europe, but to America,
I'm a believer:
Interesting. Back to see this later.
