The Department ( Ephorate ) of Paleoanthropology-Speleology is the proper institution to undertake the archaeological investigation of open spaces. What is understood by the general terms of “archaeogeology” or “geoarchaeology” is the close connection of history and archaeology with other disciplines having to do with the natural environment, more specifically those disciplines that have to do with the tetartogenous era. In organizing this office, the following archives should be assembled: a) all direct or indirect literary accounts having to do with topography, climate, geomorphology, hydrographic networks and so on, b) maps (whether topographic, geological, hydrographic, or maps of drainage, also photographs taken from the air, and c) related information coming from publications of former excavations.
