These three books between them nearly cover the whole effective range of British archaeology, from the gropings and fumblings of medieval monks to the era of pollen analysis and radio-carbon. There is a gap of nearly a century, however, between the death of Stukeley in 1765 and the beginning of Dr Daniel's hundred years. That is the unfortunate but inevitable result of adopting the rigid yard-stick of a century for measuring what in fact is the growth of living knowledge.
