This story is valuable evidence that the Eleans were at this time seeking to improve their arrangements. What the improvements were we do not know, but that some sort of reorganization took place is rendered probable by the tradition recorded above, that in Ol. 50 a second Hellanodicas was first appointed. Possibly the Olympic Council was remodelled. We find this Council in the fourth century acting as a court of appeal, and in Imperial times it is mentioned in inscriptions as authorizing the setting up of honorific statues.[77] The Hellanodicae were its executive officers, and from their history and numbers it seems probable that the Council represented the various tribes which formed a sort of amphictyony originally controlling the festival. Their existence in the sixth century is proved by the remains of their Council-house. This building lay below the south wall of the Altis. It consists of two long buildings, terminated at the west end by an apse, parallel to each other, and united by a square chamber between them. The northern wing of the building dates from the middle of the sixth century at the latest. The apsidal chamber at the end was divided by a partition, and served probably for the storage of archives and treasure, while the rest of the building formed the business quarters of the Council and the Hellanodicae. There the competitors had to appear and take an oath before the altar of Zeus Horkios that they had observed, and would observe the conditions of the festival. Another building connected with the permanent management of the festival was the Prytaneum, also built about the same time. In it was the altar of Hestia, on which the sacred fire was kept always burning. The ashes from this altar, collected and mixed with the water of the Alpheus, were used to build up the great altar of Zeus. Here, when the games were ended, distinguished guests and victors were feasted, and songs of victory were chanted in their honour. The Council must have exercised a control over all new buildings erected at Olympia. In the second half of the sixth century fresh treasuries were built by the states of Selinus, Sybaris, Byzantium, and Cyrene, a list which sufficiently illustrates the widespread influence of the festival. The planning and alignment of these buildings clearly implies the supervision of some local authority.
