Corcyra:(303) consequently they also existed in the mother-country, Corinth. It occurs likewise in another inscription of Agrigentum;(304) they must therefore have also been in existence at Rhodes, as indeed is declared by Homer.(305) The Pamphylians occur at Megara as late as at the time of Hadrian.(306) These tribes existed also at Trœzen;(307) but the Trœzenian colony Halicarnassus seems to have been almost exclusively founded by Dymanes.(308) On the whole it appears that wherever there were Dorians there were also Hylleans, Pamphylians, and Dymanes. 2. Wherever the Dorians alone had the full rights of citizenship, no other tribes of the highest ranks could exist; but if other persons were admitted in any considerable number to a share in the government, there were necessarily either one or more tribes in addition to these three. Thus a fourth, named Hyrnathia,(309) is known to us in the states of Argos and Epidaurus; in Ægina also an additional tribe of this kind must have existed, for in this island there were distinguished families not of Doric origin.(310) In Sicyon the fourth tribe was called the Ægialean. In Corinth also it appears that there were altogether eight tribes.(311) But in Sparta, the city of pure Doric customs, we cannot suppose the existence of any other than the three genuine Doric tribes. At first sight, indeed, it might appear that the great and distinguished house of the Ægidæ, of Cadmean descent, was without the pale of these tribes; but it must have been adopted into one of the three at its admission to the rights of citizenship.(312) For the number of the Spartan obæ, the gerontes, the knights, the landed estates, viz., 30, 300, 9000, &c., manifestly allow of division by the number 3, while they have no reference to the number 4.
