I'm not a scholar, just a second generation American. So consider the source.
I'm reading the Cahill book. I find it light reading, a good introduction to
a variety of things that most people don't know about of the Celtic culture.
A lot of what I am reading I've read about the same thing elsewhere.
I do find the Roman/Greek tie in to Ireland events intriguing. Makes me want
to know and read more of the classics.
I'd just as soon have the Irish save civilization as anyone else I can think
of. They don't have a bad outlook on life.
