The crucial earliest phases of palatial Knossos are not well known, in part due to over-building by Neopalatial structures and floors. This volume represents the first complete publication of substantial deposits dating to this period, specifically the Middle Minoan IB and IIA phases. This is a first not only for Knossos but for Crete as a whole, and will act as a crucial point of reference for future work on these key phases in the island's prehistory.
