The same love of beauty must have helped to check the growth of specialization with its exaggerated and one-sided development, and also to preserve the purity of sport against the influence of professionalism. Thanks largely to this ideal Olympia maintained her prestige, and to a great extent her high standard of athletic honour, long after the liberty of Greece had become a memory, and her gods a laughing-stock of the satirist. An inscription of the reign of Hadrian, discovered at Olympia, is a striking illustration of this vitality. It records a decree in honour of T. Claudius Rufus, a pankratiast of Smyrna, who, though matched in the final heat of the pankration with an opponent who had drawn a bye in the preceding heat, fought on till nightfall, and left the contest drawn.[[135]] The decree relates how he had resided at Olympia for the necessary course of training so that his σωφροσύνη was recognized by all men, how he had trained according to the traditional customs of the games, and had in the stadium given an exhibition worthy of Olympian Zeus, and of his own training and reputation, in recognition of which the Eleans had voted him the right of erecting his statue in the Altis. The decree is perhaps somewhat fulsome, and suggests that such examples of σωφροσύνη must have been exceptional at the time. Yet it shows that the memory at least of the old ideal survived even under the empire and was still cherished at Olympia.

We have already seen what an impulse was given to athletics and to the Panhellenic festivals by the Persian wars. No festival was more Panhellenic than that of Olympia, and no place felt more keenly than Elis the invigorating effects of the new spirit of unity and of freedom. Elis had played an inglorious part in the national struggle. The narrow and unprogressive oligarchy showed the same lack of energy and initiative which they had shown in the management of the Olympic festival during the sixth century. The Elean contingent arrived at Plataea too late to take part in the battle. Returning home full of bitter self-reproach they at once determined to put an end to the old régime, and banished the leaders who had been responsible for the fiasco. This was the beginning of the Synoecism of Elis which was not finally completed till 471 B.C., when the government of the scattered, unwalled villages was for the first time centred in the newly founded city state of Elis. The change was facilitated by the eclipse of Spartan prestige in the Peloponnese, while the growing influence of Athens was clearly shown both in these political changes and in the outburst of artistic activity at Olympia which followed the founding of Elis. But the new order could not fail to excite violent opposition, especially among the conservative folk of Pisatis and Triphylia, and their opposition culminated in a civil war which only ended about the year 470 or 469 with the devastation of the whole district by the Eleans.

The opposition of Pisatis was due partly to the transference of the political centre to Elis, perhaps in a greater degree to the new régime inaugurated at Olympia. The old dual control of the festival by Elis and Pisatis was, as we have seen already, passing away; possibly its death-blow was given by the banishment of the aristocrats, some of whom may have had hereditary connexion with the festival. At all events, from the time of Plataea the two Hellanodicae who represented the dual control were replaced by a board of nine,[[136]] and permanent quarters were provided for the new administration by the enlargement of the Bouleuterion, the south wing of which was added about this time. The increase in the number of officials may have been rendered desirable by the increasing strenuousness of the competitions. The nine were divided into three groups of three each, in charge respectively of the horse-races, the pentathlon, and the other athletic events, an excellent arrangement which at once commends itself to the modern athletic mind. Yet it seems more likely that the number nine was dictated by political considerations, and the fact that there were nine tribes of the Eleans. It was a change to a sort of popular representation, and its popular character is further marked by the fact that these officials were elected by lot, a democratic institution which can hardly have belonged to the earlier régime.

This change first took effect in Ol. 76, and possibly was introduced in view of that great national Olympiad. It was on this occasion, according to a popular story, that Themistocles himself appeared and received such an ovation from the crowd that the athletes themselves were neglected. The national character of this Olympiad assured the success of the new order. In the following festival the competition was so great that the pankration could not be decided before nightfall, and it was decided from this date to extend and rearrange the festival. In the 77th Olympiad, too, a tenth Hellanodicas was added apparently to represent the newly conquered district of Triphylia. This number remained unchanged till Ol. 103, when, the number of tribes having been raised to twelve in consequence of a still further extension of territory southwards, a corresponding change was made in the number of the Hellanodicae. The war with Arcadia which ensued reduced the number for a time to eight, but in Ol. 108 the number was restored to ten and no further change was made. These Hellanodicae must be regarded as the executive officers of the Elean Council, to whom in case of doubt or dissatisfaction there was a right of appeal.

The intimate connexion between the political changes in Elis and the Olympic festival can be best realized from Pausanias’ account of the new city.[[137]] Everything in Elis seems to have been planned purely and simply with a view to the festival. The agora was nothing more or less than a training-ground for horses, it was a large open square or oblong surrounded by colonnades with no other ornaments than a few altars to Zeus and other gods, and even these so constructed as to be easily removable. Close to this agora, appropriately called the hippodrome, were no less than three gymnasia with running tracks, and rings for boxing or wrestling, and conveniently connected with agora and gymnasium was the Hellanodiceon, or headquarters of the Hellanodicae. Here the latter had to reside for ten months before the festival, receiving instruction in all the ancient usages of the games from the Guardians of the Lavs (Nomophylakes). During the last month before the games they themselves were engaged in superintending the practice of the athletes, who spent the last thirty days of their training at Elis, and in classifying men and horses according to age, a matter of no little difficulty when no registers of births were kept. The principal buildings of Elis city were all connected with the games, and though we cannot tell the date of those which Pausanias saw, there can be little doubt that they truly indicate the character of the city from the start. The agora was typical of the rest, and Pausanias pointedly contrasts it with the cheerful market-places of Ionian towns. Certainly it cannot have been an attractive place to live in, and the Eleans never took kindly to it; indeed many an old-fashioned country gentleman lived and died without even setting foot in his chief city.[[138]]

Meanwhile great changes were taking place at Olympia. Its national character was recognized by the dedication in the Altis, from the spoil of Plataea, of a colossal bronze statue of Zeus, on the base of which were inscribed the names of all states which had taken part in the battles. But the new feeling of national unity found a yet worthier monument in the whole series of buildings which the new administration undertook, to render the sacred precinct worthy of its Panhellenic dignity. Hitherto, as we have seen, various states had been allowed to secure for themselves points of vantage at the festival by building, along the foot of the hill of Cronus, treasuries, or communal houses. Three more of these buildings—the last of them—were added shortly after Plataea. All these were at the western end of the terrace. One of them was dedicated by the Syracusans in commemoration of their victory over the Carthaginians at Himera; another was built by the Sicyonians, possibly on the site of an older foundation, containing the great bronze treasure-chests dedicated by Myron; the builders of the third are unknown, but it has been plausibly suggested that they were the Samians. Sicyon had played an important part in the war with Persia both by land and sea, Samos was closely connected with the victory at Mycale, and it is tempting to imagine that both these treasuries were memorials of the national victory. This, however, is mere conjecture; what is certain is, that these treasuries were built shortly after Plataea and that from this date the building of such treasuries ceases abruptly. Henceforth the Eleans took into their own hands the embellishment of the Altis, and their first work was in connexion with the treasuries.[[139]]

The loose nature of the soil had rendered the building of the westernmost treasuries a matter of considerable difficulty. Accordingly, the Eleans constructed nine rows of stone steps extending continuously from the western end of the Heraeum along the whole length of the treasury terrace. These steps not only served as a retaining wall to the treasuries but furnished a capacious stand from which thousands of spectators could view the games and sacrifices, which still centred round the altar of Zeus. Shortly afterwards was built the additional wing of the Bouleuterion mentioned above.

The next move of the Eleans was to provide a temple worthy of Olympian Zeus, and the money for this work was provided from the plunder gained in Triphylia and Pisatis. The new temple was begun about the year 468 B.C., and perhaps its buildings suggested to Pindar the opening lines of his 6th Olympian Ode in which he compares the prelude of his song to the façade of a stately fane. The temple must have been completed about the time of the defeat of the Athenians and Argives by Sparta at Tanagra in 457; for the Spartans commemorated their victory by a golden shield which was placed on the summit of the temple. It would be out of place here to attempt any description of the temple: we may notice, however, that while the architect Libon was an Elean, the great chryselephantine statue of Zeus afterwards erected in it was the masterpiece of Pheidias, and Pausanias ascribes some of the sculptural decorations to the Athenian sculptors Paeonius and Alcamenes, though modern authorities generally discredit the statement. And just as Pheidias in his Zeus tried to represent the highest ideal of Greek manhood, so in the lesser works, the mythological scenes of the pediments and metopes, the chariot-race of Pelops and Oenomaus, the battle of the Lapiths and Centaurs, the labours of Heracles, we have in reality various renderings of the theme which inspires all the art of this period, the triumph of the Greek over the barbarian, of trained skill over undisciplined force. Thus the temple of Zeus was truly a national memorial of the Persian wars.

The new temple was built on the site of the ancient grove, and its building had no doubt interfered with anything in the nature of fence or hedge which may have bounded the sacred grove. Perhaps we may assign to this period the idea of marking out the Altis in the rough quadrilateral shape which has been revealed by later ruins. This plan seems to be implied in the building of the first colonnade at the eastern end of and at right angles, to the treasury terrace. This colonnade was built about the middle of the fifth century, and was obviously intended for the convenience of spectators at the festival, commanding, as it did, a full view of the ancient altar and of the east end of the newly built temple of Zeus. Its building necessitated a change in the athletic arrangements.

The foot-races could no longer take place near the altar, and a new permanent “dromos,” or race-course, was provided to the east of the colonnade. This may have been partly a concession to the growing demands of professional athletes, but the new race-course was still of the simplest. The ground was approximately levelled, the course was measured and perhaps marked by a permanent line of stone slabs at either end, and water-channels were provided to carry the water from the west of the Altis to the race-course, for the convenience of spectators and athletes alike. Perhaps permanent seats were provided for the Hellanodicae, and for the priestess of Demeter Chamyne, who had a place of honour opposite them. The rest of the spectators had no seats, but reclined or stood on the slopes of the hill of Cronus, or else on the flat plain that stretched between the stadium and the Alpheus.
