" Nothing could have been less in line with contemporary conceptions of art than that the theatre should be divorced from all relation to life and politics. Greek tragedy was in the strictest sense ‘political drama’; the finale of Eumenides, with its fervent prayers for the prosperity of the Attic state, betrays the main purpose of the piece. This political control of the theatre brought back to currency the old view that the poet is guardian of a higher truth and an educator who leads his people up to a higher plane of humanity. Through the performance of tragedies on the state-ordained festivals and the circumstances that tragedy came to be looked upon as the authoritative interpretation of the national myths, the poet once more attains to a position almost equivalent to that of the priestly seer of prehistoric times.
