What is the author's style in Electra by Hugo von Hofmannsthal?

The play observes the three unities of time, place, and action. This was a concept of dramatic structure that derived in part from Aristotle and was completed in the sixteenth and seventeenth centuries. The unities require that the actions represented by the play take place over a period of not more than one day, at a single location, with all the action focusing on a single plot. There are no subplots, comic characters or other diversions. The play also observes the convention of Greek drama that violent acts are reported rather than being shown directly on stage. For this reason, the killing of Clytemnestra and Aegisthus is not shown directly.
