I met Barry Fell 30 some years ago at a conference. Interesting guy, I can’t say I buy into all his theories. Some of his Ogam translations seem to be wishful thinking. However the one thing I do agree with is “classical history education” sells ancient short when it comes to their ability to do things like travel! You don’t need Martians to explain what ancient people did. You just have to imagine that Man is very clever even if he’s carrying a stone tipped spear.
And I have both his books!
I think he’s been dead for quite awhile.
I exchanged a few letters with him back in, hmm the early- to mid-80s, very smart, easy to understand, courteous, and obviously a polymath. Besides his three books (beginning with "America B.C.") he had loads of papers in the ESOP (Epigraphic Society Occasional Publications) that were interesting. He grew up in New Zealand and was welcome among the various indigenous groups, and has indeed been dead a while now.
