In his last talk Mr. Casson will deal with Olympia, perhaps the most famous of all ancient Greek towns, where the great athletic. contests were held and where the finest examples of Greek art were set up in honour of the gods. It is almost impossible to rate these Olympic festivals too highly; Olympiads were a universal method of reckoning time, and to have won at Olympia made a man famous, not only in his own particular state, but throughout all Hellas. Olympia has revealed many surprising 'finds' to modern archaeologists.
