I have been reading two books as part of my background research for Book 4 of the Conall series, which has already 13,000 words written. The books are Europe Before Rome by T.Douglas Price and The Ancient Celts by Barry Cunliffe. Both are highly recommended–very readable with lots of great photos, maps and illustrations.
However, as I perused the pages and reflected on similar books on other ancient civilizations, I came to the conclusion that civilization has been regressing for the past two or three thousand years. The art, architecture and major projects of the Ancient World were accomplished without modern technology.
It is so sad that modern man cannot rise to the same or greater level of achievement as his ancient ancestors.
