This remark would seem to apply more precisely to the arrangement of the dialogues into trilogies and tetralogies.
Why, if the old Greeks had had this man, what trilogies of plays—what epics—would have been made out of him!
In comparing Sophocles with his predecessor, we must never forget that we are comparing single plays with trilogies.
This work he has divided into three trilogies, and five of the nine books have been published.
The other tragedians do not seem to have written in trilogies, and Euripides at any rate moved gradually away from satyr-plays.
