Other than presumably selecting the pieces for inclusion, Ceram appears to have little to do with the text of this book, many, if not all, of the introductory biographical essays being composed, and credited, to another. One supposes that this book followed the wake of success attending his previous.
What this amounts to are many essays written from the 18th to the mid-20th centuries by amateur and professional archaeologists, most of the authors and their topics (usually sites of Africa, Asia, Europe or South America) being well known. As such, it makes for a good bedtime book, the selections being short.
