Each city had its costly edifices devoted to this purpose. The Stadion at Athens, within whose restored walls the modern games took place, was about six hundred and fifty feet long and one hundred and twenty-five wide, the race-course itself being six hundred Greek feet—a trifle shorter than English feet—in length. Other cities were similarly provided, and gymnastic exercises were absolute requirements of the youth of Greece,—particularly so in the case of Sparta, in which city athletic exercises formed almost the sole occupation of the male population.

But the Olympic Games meant more than this. They were not national, but international festivals, at whose celebration gathered multitudes from all the countries of Greece, those who desired being free to come to and depart from Olympia, however fiercely war might be raging between the leading nations of the land. When the Olympic Games began is not known. Their origin lay far back in the shadows of time. Several peoples of Greece claimed to have instituted such games, but those which in later times became famous were held at Olympia, a town of the small country of Elis, in the Peloponnesian peninsula. Here, in the fertile valley of the Alpheus, shut in by the Messenian hills and by Mount Cronion, was erected the ancient Stadion, and in its vicinity stood a great gymnasium, a palæstra (for wrestling and boxing exercises), a hippodrome (for the later chariot races), a council hall, and several temples, notably that of the Olympian Zeus, where the victors received the olive wreaths which were the highly valued prizes for the contests.

This temple held the famous colossal statue of Zeus, the noblest production of Greek art, and looked upon as one of the wonders of the world. It was the work of Phidias, the greatest of Grecian sculptors, and was a seated statue of gold and ivory, over forty feet in height. The throne of the king of the gods was mostly of ebony and ivory, inlaid with precious stones, and richly sculptured in relief. In the figure, the flesh was of ivory, the drapery of gold richly adorned with flowers and figures in enamel. The right hand of the god held aloft a figure of victory, the left hand rested on a sceptre, on which an eagle was perched, while an olive wreath crowned the head. On the countenance dwelt a calm and serious majesty which it needed the genius of a Phidias to produce, and which the visitors to the temple beheld with awe.

The Olympic festival, whose date of origin, as has been said, is unknown, was revived in the year 884 B.C., and continued until the year 394 A.D., when it was finally abolished, only to be revived at the city of Athens fifteen hundred years later. The games were celebrated after the completion of every fourth year, this four year period being called an "Olympiad," and used as the basis of the chronology of Greece, the first Olympiad dating from the revival of the games in 884 B.C.

These games at first lasted but a single day, but were extended until they occupied five days. Of these the first day was devoted to sacrifices, the three following days to the contests, and the last day to sacrifices, processions, and banquets. For a long period single foot-races satisfied the desires of the Eleans and their visitors. Then the double foot-race was added. Wrestling and other athletic exercises were introduced in the eighth century before Christ. Then followed boxing. This was a brutal and dangerous exercise, the combatants' hands being bound with heavy leather thongs which were made more rigid by pieces of metal. The four-horse chariot-race came later; afterwards the pancratium (wrestling and boxing, without the leaded thongs); boys' races and wrestling and boxing matches; foot-races in a full suit of armor; and in the fifth century, two-horse chariot-races. Nero, in the year 68 A.D., introduced musical contests, and the games were finally abolished by Theodosius, the Christian emperor, in the year 394 A.D.

Olympia was not a city or town. It was simply a plain in the district of Pisatis. But it was so surrounded with magnificent temples and other structures, so adorned with statues, and so abundantly provided with the edifices necessary to the games, that it in time grew into a locality of remarkable architectural beauty and grandeur. Here was the sacred grove of Altis, where grew the wild olive which furnished the wreaths for the victors, a simple olive wreath forming the ordinary prize of victory; in the four great games the victor was presented with a palm branch, which he carried in his right hand. Near this grove was the Hippodrome, where the chariot-races took place. The great Stadion stood outside the temple enclosure, where lay the most advantageous stretch of ground.

The training required for participants in these sacred games was severe. No one was allowed to take part unless he had trained in the gymnasium for ten months in advance. No criminal, nor person with any blood impurity, could compete, a mere pimple on the body being sufficient to rule a man out. In short, only perfect and completely trained specimens of manhood were admitted to the lists, while the fathers and relatives of a contestant were required to swear that they would use no artifice or unfair means to aid their relative to a victory. The greatest care was also taken to select judges whose character was above even the possibility of bribery.

Women were not permitted to appear at the games, and whoever disobeyed this law was to be thrown from a rock. On certain occasions, however, their presence was permitted, and there were a series of games and races in which young girls took part. In time it became the custom to diversify the games with dramas, and to exhibit the works of artists, while poets recited their latest odes, and other writers read their works. Here Herodotus read his famous history to the vast assemblage.

Victory in these contests was esteemed the highest of honors. When the victor was crowned, the heralds loudly proclaimed his name, with those of his father and his city or native land. He was also privileged to erect a statue in honor of his triumph at a particular place in the sacred Altis. This was done by many of the richer victors, while the winners in the chariot-races often had not only their own figures, but those of their chariots and horses, reproduced in bronze.
