FROM CLASSICAL TO BYZANTINE

(1) A descriptive problem - gathering more information about the Medieval occupation at Isthmia, delineating the structural features of the Byzantine Fortress with the ultimate intent of comprehending site functions through time. (2) A methodological problem - the use of geophysical techniques to examine the subsurface of the Fortress and other selected spots to obtain the data necessary for proper description. (3) A broader historical problem - how best to reconstruct the key events pertaining to the transition from Late Antiquity to Early Byzantine. The methodological element becomes the link between the gathering of site-specific data and the wider historical implications for that information.
