This fable would intimate a Hellenic origin, since Deucalion is the fabled founder of the Hellenes; but out of twelve tribes which composed the confederacy, only three were Hellenic, and the rest Pelasgic. But with the increasing influence of the Dorian oracle of Delphi, with which it was connected, it became gradually considered a Hellenic institution. It is not possible to decipher the first intention of this league. The meeting was held at two places, near Anthela, in the pass of Thermopylae, and Delphi; at the latter place in the spring, at the former in the autumn. If tradition imputed to Amphictyon the origin of the council, it ascribed to Acrisius, king of Argos [80], the formation of its proper power and laws. He is said to have founded one of the assemblies, either that in Delphi or Thermopylae (accounts vary), and to have combined the two, increased the number of the members, and extended the privileges of the body. We can only interpret this legend by the probable supposition, that the date of holding the same assembly at two different places, at different seasons of the year, marks the epoch of some important conjunction of various tribes, and, it may be, of deities hitherto distinct. It might be an attempt to associate the Hellenes with the Pelasgi, in the early and unsettled power of the former race: and this supposition is rendered the more plausible by the evident union of the worship of the Dorian Apollo at Delphi with that of the Pelasgian Ceres at Thermopylae [81]. The constitution of the league was this-- each city belonging to an Amphictyonic state sent usually two deputies--the one called Pylagoras, the other Hieromnemon. The functions of the two deputies seem to have differed, and those of the latter to have related more particularly to whatsoever appertained to religion. On extraordinary occasions more than one pylagoras was deputed--Athens at one time sent no less than three. But the number of deputies sent did not alter the number of votes in the council. Each city had two votes and no more, no matter how many delegates it employed. All the deputies assembled,--solemn sacrifices were offered at Delphi to Apollo, Diana, Latona, and Minerva; at Thermopylae to Ceres. An oath was then administered, the form of which is preserved to us by Aeschines. "I swear," runs the oath, "never to subvert any Amphictyonic city-- never to stop the courses of its waters in peace or in war. Those who attempt such outrages I will oppose by arms; and the cities that so offend I will destroy. If any ravages be committed in the territory of the god, if any connive at such a crime, if any conceive a design hostile to the temple, against them will I use my hands, my feet, my whole power and strength, so that the offenders may be brought to punishment." Fearful and solemn imprecations on any violation of this engagement followed the oath.
