firstly, it has got to be said... this book is marvellous. Its scope is huge, but well researched and very well written.
Wengrow combines archaeology and anthrapology to study egypt and her cultural influences in her earliest days, prior to the unification of Egypt. With an absolute lack of historical (literary) evidence for the period, Wengrow focusses on the archaeological evidence from Egypt and uses it to link her rise into a powerful state, and how interaction with such contemporary powers (Mesopotamia, Nubia, sub-Saharan Africa etc) influenced egypt economically, politically and in terms of trade.
The book is separated into two parts; transformation in prehistory, which looks at earliest egypt, within an archaeological context. The second part, "the making of kingshp" explores the cultural changes that led to the unification of the egyptian state.
the layout is accessible, and an appendix which details the different contemporary time period is very useful. Furthermore, there is a sufficient number of illustrations throughout the book, although none in colour.
In terms of language, the book is designed for all. It does not scare off the amateur egyptologist, yet it is sufficient for the masters in the field.
I cannot recommend this book highly enough. David Wengrow, you should be proud.
