The Predynastic cultures of Egypt, which predated the unification of the country under one king and the beginning of dynastic history in approximately 3000 BC, were first discovered independently by Flinders Petrie and de Morgan in the 1890s, laying solid foundations for the study of the period.  As fieldwork in Egypt continues and the subject expands, the literature has become specialised and scattered; this book gives a concise introduction to the sources and types of matierial remains relating to Predynastic Egypt, and explains how they were used to provide information on the developement of a society with no written language.
