An extensive study of city planning in the Greek Archaic colonies (Sicily and Southern Italy) from HApodamus and beyond. The author sets out to consider the legacy of the great planner and those projects he may have contributed to. The first section of the work focuses on 12 specific sites (Syracuse, Metapontum, Selinus, Neapolis, etc.), while the second section traces the developmental features of the characteristic grid pattern of the planned city, taking into account the social, economic, and political aspects that evolved. The detailed bibliography includes sub-sections arranged by site.
