The festival was from the first under the charge of the Eleians. But so liberal a policy did this nation adopt and pursue that people from neighboring states were glad to send competitors. Rapidly the custom of resorting to the games spread to more     1    (遥远的，远处的) states. From an Eleian event, the festival finally became Panhellenic. The Athenians and Thebans at a very early date achieved splendid victories in these games. The Theban Pagondas was crowned victor in the four- horse chariot race in the 25th Olympiad, when for the first time this was a feature of the festival. Thus one state after another turned its     2    (注意，注意力) to the venerable celebration, and if it happened that a citizen of one state was crowned victor in a contest, interest in the games was sure to be increased in that locality.

Even in the absence of positive evidence it would be contrary to reason to suppose that the games were originally established as they existed at the time of Pindar. In fact, the different features were added successively. According to a fairly reliable tradition, there was originally and for 12 following Olympiads only one contest: a foot race     3     of (由……组成) a single lap of a stadium of 200 yards. Boxing and the chariot race are said to have been added in the 23rd Olympiad. Thus the games grew more elaborate, and the time over which they extended was increased from a     4    (仅有一个的，单个的) day to five or six.

The festival was conducted by judges elected by the people of Elis a year beforehand. The number of these judges was about ten; they were expected to give close attention to their duties. Thirty days before the festival, candidates for the various contests presented themselves before the judges for examination. The names of those who were able to     5     (使……满意，满足) the judges were placed on a white board which was exposed to view at Olympia.
