It is quite a good book… but it NEEDS a new edition (more of this later).
The book is well written and I think easy to understand for casual readers who have interest in the history of Africa. The book’s interest is the period from prehistory to (around) the 7th Century.
One third of the book mainly treats ancient Egypt, the second third treats the horn of Africa and the remaining Mediterranean Africa, the last third talks about the remaining continent (sub-Saharan). This is simply due to the fact that the first 2/3 of the book have available plenty of written resources while the other part of the continent have to rely strongly on archeology. Archeology that in some cases i s impossible to obtain (due to geographical conditions, e.g., soils that do not allow fossilization), and in other cases is entirely missing (e.g., Angola). But overall, it is well written, with some chapters that are easier to read than others (depending on the historian of course).
The book itself is quite good and I really appreciated the fact that when theories are presented they are presented as such. Unfortunately, I saw often people online quoting this book and these theories as absolute facts. Obviously not fault of the author. I appreciated the abridged version of the Cairo proceeding after the first chapter by professor Anta Diop, simply because it is important to state that often some historians will push some theories more than others. There are also sometimes different point raised by different historians. I think this shows very well to the casual reader that often history is not as straightforward as they think, but often there are no answers, but more or less probable theories, which evolve in time depending on new discoveries.
It is mentioned in the book that before the 60s it was believed that sub-Saharan metallurgy originated in East Africa around 1000, but later research found that it originated in west africa some 1500 earlier than east Africa. I think this thing alone shows how “flexible” and “evolving” historic knowledge is.
It must be said though, the book is quite old and throughout the book we read often things along the lines of “we await more research in this”, “new research is being conducted” or “we wait for the results of new research”. It is clear that a lot of nove research was being conducted on the time this book was written, a book published in the 80s, with the majority of sources coming from the 60s (rarely from the early 70s)… I wonder what were the results of these researches. Moreover, the historians suggest, where key research is missing, which directions should be taken, quite often in the book… did any historian or PhDs follow these routes? Did anybody manage to translate some Meroitic languages?
I guess we readers who are interested in the matter will have to find these answers elsewhere, but it would’ve been nice already having them in a newer edition of the book, because some of us are reading it 40 years after its publication.
