From “Under the Ancient Oaks”:

「A book to avoid

I love recommending books that I find helpful. I generally ignore books I don’t like, but occasionally I come across something that needs a warning on it. One such book is The Celts: A Sceptical History by Simon Jenkins.

Celtic scholar and author Danu Forest said “I don’t believe in being the Celtic Studies police but this really is toxic nonsense and poor scholarship that was only published due to its emergence from the Westminster bubble.”

This review https://nation.cymru/culture/review-the-celts-a-sceptical-history-by-simon-jenkins/ from Nation Cymru in Wales calls it “irresponsible” “lazy” and says “he makes elementary errors that could have been corrected by looking at Wikipedia. Overall, this is like reading an essay by a clever, ambitious but lazy and contrarian undergraduate, with far too high a regard for his own cleverness.”

Spend your money – and your reading time – elsewhere.」
