Of the beginnings of these great solemnities we cannot presume to speak, except in mythical language; we know them only in their comparative maturity. But the habit of common sacrifice, on a small scale and between near neighbors, is a part of the earliest habits of Greece. The sentiment of fraternity, between two tribes or villages, first manifested itself by sending a sacred legation or Theoria to offer sacrifices to each other's festivals and to partake in the recreations which followed; thus establishing a truce with solemn guarantee, and bringing themselves into direct connexion each with the god of the other under his appropriate local surname. The pacific communion so fostered, and the increased assurance of intercourse, as Greece gradually emerged from the turbulence and pugnacity of the heroic age, operated especially in extending the range of this ancient habit: the village festivals became town festivals, largely frequented by the citizens of other towns, and sometimes with special invitations sent round to attract Theors from every Hellenic community--and thus these once humble assemblages gradually swelled into the pomp and immense confluence of the Olympic and Pythian games. The city administering such holy ceremonies enjoyed inviolability of territory during the month of their occurrence, being itself under obligation at that time to refrain from all aggression, as well as to notify by heralds the commencement of the truce to all other cities not in avowed hostility with it. Elis imposed heavy fines upon other towns--even on the powerful Lacedaemon--for violation of the Olympic truce, on pain of exclusion from the festival in case of non-payment.
