Here, as at Olympia, punctual attendance was required of the competitors; those who entered unlawfully were expelled by the servants of the Amphictyons, who were entrusted with disciplinary power. It was they who had the superintendence of the games, as well as the right of judging. Originally both these privileges had belonged to the inhabitants of Delphi; but after the reorganisation of the games in the year 586, the duties of superintendents and judges passed to the Amphictyons, or to officials appointed by them. It seems that we must distinguish between the Amphictyonic superintendents (ἐπιμεληταί), in whose hands were the arrangement of the programme, and all matters of expense, the appointment or ratification of the festive officials, etc. (ἀγωνοθεσία), and the real umpires (βραβῆς), who had themselves to make the most important arrangements for the contests, such as assigning the places for the chariots in the races and giving decisions about the victory; but we cannot attain any certainty in this matter. Sometimes, towards the end of the age of Greek freedom, the right of superintendence was conferred on princes--as, for instance on Philip of Macedon--and in the time of the Empire it was not unusual for a rich man to bear the expenses of the ceremony wholly or in great part; though even here the old custom was, at any rate externally, observed. The prizes of victory were originally valuable gifts, tripods, etc.; at the rearrangement of the games the custom originated of giving, instead, a wreath, as was done at Olympia, made of laurel sacred to Apollo. They also followed the example of Olympia in introducing lectures and recitations by historians and poets; thus Gorgias the Sophist, delivered an oration on one of these occasions. A very important part of the festival was the great procession (πομπή), in which strangers who came to the games, embassies with their dedicatory offerings, the officials and priests, took part; and besides the offerings, which were often very splendid, valuable treasures, usually kept in the treasuries, were exhibited; costly weapons and armour, splendid garments and jewels, vases, etc., were exposed to view, so that this procession, which probably marched from the suburb Pylaea, upwards to the temple of Apollo, must have presented a very varied and richly-coloured picture. As well as the triple sacrifice already mentioned, there were other solemn sacrifices, among them a hecatomb to Apollo; this was, of course, connected with the great banquet, at which there was no lack of musical entertainment.
