Sharon E.J. Gerstel and Michalis Kappas examine regional monumental painting in the southern Peloponnese dated to the thirteenth and fourteenth centuries. Just like many other former Byzantine territories in the wider Mediterranean, which after 1204 passed to western rule, in Messinia and Lakonia the symbiosis between the native Greek Orthodox population and the western Roman Catholic colonists is attested in the artistic production of the period in the area. The long-term co-habitation had a profound impact on painting styles in the region, visualising the cross-cultural interaction and dialogue between the different sets of inhabitants.
