The classical world witnessed many forms of landscape change in its physical geography, mostly due to longer-term geological and climatological processes, whilst only a minority were due purely to human action. The physical environment of Greek and Roman societies saw alterations through earthquakes, volcanic eruptions, sea-level fluctuations, erosion, and alluviation.
Already in Greek antiquity, Plato (Critias iii) observed how the Aegean physical landscape was being worn down over time as erosion from the uplands filled the lowland plains. Indeed, the Mediterranean region is amongst the most highly erodible in the world.1 However, scientific research in the field known as geoarchaeology has revealed a more complex picture than a continuous degradation of the ancient countryside.2
To uncover a more realistic picture of Mediterranean landscape change, the element of timescales proves to be central, and here the framework developed by the French historian Fernand Braudel3 provides the appropriate methodology. Braudel envisaged the Mediterranean past as created through the interaction of dynamic forces operating in parallel but on different “wavelengths” of time: the Short Term (observable within a human lifetime or less), the Medium Term (centuries or more, not clearly cognisant to contemporaries), and the Long Term (up to as much as thousands or millions of years, not at all in the awareness of past human agents).
