When the authors of this book met at the London Institute of Archaeology in 1985, we discovered a mutual scepticism of the claimed accuracy for the timetables of Old World archaeology. Above all, we became increasingly convinced that something was seriously wrong with the conventional picture of a centuries-long Dark Age descending over a vast area at the end of the Late Bronze Age c. 1200 BC. With a background of research in many different but related fields (specifically prehistoric Britain, Minoan Crete, Mycenaean Greece, biblical archaeology and Pharaonic Nubia), we pooled our resources and began an in-depth investigation of the archaeological chronology of the entire ancient Mediterranean and Near East. Everything we found confirmed our suspicion that the original spanner in the works was the Egyptian time-scale, and that the 'centuries of darkness' inserted into the histories of so many areas between 1200 and 700 BC were largely illusory.
I've found their book to be a little too technical to take in all the details, but clearly they've been very thorough, covering the entire ancient Mediterranean and Near East in making their case that the accepted chronology has created myriad problems in dating for every ancient archaeological find in those geographical areas.
