[EN] From the moment a granitic magma begins to cool until it is solidified it is subjected to stress and strain, producing the various discontinuities that can be seen in the finally exposed rock. When as a result of the erosion of superincumbent rocks the granite is at or near the land surface these discontinuities are exploited by weathering. Such features, and particularly those related to fractures or diaclases, outline forms that are considered here as primary endogenous forms. Once the rock is in the earth surface, various external agencies first soil weathering and later others as gravity, rivers, waves, glaciers, frost, wind, attack the rock to produce new suites of forms that are considered here as primary exogenous either etched or subaerial features. Such primary forms, both endogenous and exogenous, can evolve morphologically further as a result of subaerial weathering and erosion, becoming secondary endogenous or secondary exogenous forms. Exceptionally, some primary, either exogenous or endogenous, features can survive to successive morphogenetic episodes either below sedimentary burial or just subaerially without appreciable modification by external agencies being considered as inherited forms. Only the discernment of all these types of landforms allows the complete understanding of the geomorphological history of the area in which they occur.

Das Mittelmeer als historischer Raum diente in der ersen Hälfte des 20. Jahrhunderts als Paradigma für bahnbrechende historiographische Experimente, die den Fokus vom Einzelereignis hin zu ausgedehnten historischen Prozessen überführten. Die aus der Annalen-Schule stammende Prägung der "Longue durée" durch Fernand Braudel führte zu einem wahren Paradigmenwechsel. Dieser Vortrag diskutiert die heutigen Perspektiven auf das Mittelmeer als Raum und die Bedeutung bzw. fehlenden Bedeutung, die der Musik bei der Definition des MIttelmeers als Studienobjekt durch die allgemeine Geschichte beigemessen wurde.
