With the exception of the reserved places in the front rows, the rest of the auditorium consisted of the ordinary two-obol seats. Concerning the arrangements adopted in this part of the theatre a few details have been recorded. It appears that special portions of the auditorium were set apart for the different classes of the community. There was a particular place for the members of the Council of Five Hundred, and another place for the Ephebi, or youths between the age of eighteen and twenty.[1028] The women were separated from the men, and the courtesans sat apart from the other women.[1029] It is probable that all the women sat at the back of the theatre, at a long distance from the stage. Foreigners also seem usually to have had a special place.[1030] The amphitheatre of seats was divided into thirteen blocks by the passages which ran upwards from the orchestra. It is very probable that in the arrangement of the audience each tribe had a special block assigned to it. The blocks of seats were thirteen from the first. The tribes were originally ten, though they were raised in later times to twelve and thirteen. It is possible that the three unappropriated blocks were assigned respectively to the Council, the Ephebi, and Foreigners.[1031] But the excavations in the theatre afford grounds for inferring that there was a connexion between certain blocks and certain tribes, and the thing is not improbable in itself.[1032] The tribal divisions played a large part in the various details of Attic administration, and an arrangement by tribes would have greatly facilitated the process of distributing the enormous mass of spectators among their proper seats.
