Twenty years ago one of the editors of this volume, John Cherry of the University of Michigan, looked forward to a day when the 'Frogs round the Pond' (active intensive survey projects working around the Mediterranean) could produce real insights into the development of human societies by comparing and synthesizing the data they had collected. Despite the theoretical advances in survey methodology that have been discussed and implemented since that date, few scholars (with the exception of Sue Alcock, the other editor - also at Michigan) have attempted to use survey data to answer the real questions social historians have been asking. In this volume a number of prominent scholars re-commit to the original goal of intensive survey projects and discuss what original insights over twenty years of survey work have brought to our understanding of the Mediterranean world.
