Recently, I've been reading about the Greek playwright Euripides.  It is said that Socrates rarely attended plays, but never missed a play by Euripides.  Technology has changed dramatically since the fifth century B.C.E., but it seems that some things don't change very much at all.

In Iphigenia in Aulis, Euripides tells the story of how Agamemnon got the Greek army moving against Troy.  Agamemnon was the brother of Menelaus, the King of Sparta who had been cuckolded by his wife Helen.  Keen on restitution of the errant spouse, if not revenge against her paramour, the two brothers roused the Greeks to sail to Troy.  The Greeks didn't make it very far when they became becalmed in Aulis.  An oracle tells Agamemnon that he must sacrifice his daughter, Iphigenia, to get a favorable wind. Evidently not vying for "father of the year", Agamemnon decides to do what needs to be done, but then changes his mind.  His brother, Menelaus, then upbraids Agamemnon, taking him to task for changing after achieving power:

οἶσθ᾽, ὅτ᾽ ἐσπούδαζες ἄρχειν Δαναΐδαις πρὸς Ἴλιον, τῷ δοκεῖν μὲν οὐχὶ χρῄζων, τῷ δὲ βούλεσθαι θέλων,  ὡς ταπεινὸς ἦσθα, πάσης δεξιᾶς προσθιγγάνων καὶ θύρας ἔχων ἀκλῄστους τῷ θέλοντι δημοτῶν  καὶ διδοὺς πρόσρησιν ἑξῆς πᾶσι — κεἰ μή τις θέλοι —  τοῖς τρόποις ζητῶν πρίασθαι τὸ φιλότιμον ἐκ μέσου;  κᾆτ᾽, ἐπεὶ κατέσχες ἀρχάς, μεταβαλὼν ἄλλους τρόπους  τοῖς φίλοισιν οὐκέτ᾽ ἦσθα τοῖς πρὶν ὡς πρόσθεν φίλος, δυσπρόσιτος ἔσω τε κλῄθρων σπάνιος.

You know that you were eager to lead the Danaans [the Greeks] to Ilion [Troy], to seem to be unwilling, but wanting your wish; you were humble, taking everyone by the right hand, willing to keep your doors open to the common folk, offering to speak with one after another - even the unwilling - seeking in this way to buy affection from all.  But when you gained power, you changed direction.  You were no longer friendly to your former friends, became difficult to access and kept your doors barred.

Euripides, Iphiginia in Aulis l. 337-348 (my translation).

Euripides hasn't found much of a following in California decisions.  However, the California Supreme Court did invoke the playwright in the famous obscenity case of Barrows v. Municipal Court, 1 Cal.3d 821 (1970):

Use of the theater to depict current events, as distinguished from religious pageantry, was first attempted by Aeschylus, and refined by Euripides and later by Aristophanes who mastered comedy.

Fear of the political potential of the theater was manifest when James I published an ordinance forbidding representation of any living Christian king upon the stage.  Since 1624 the lord chamberlain has had censorship control of the English theater. (See VII Ency. Soc. Sciences, 598 ff.)

Id. at n. 4.  Barrows involved the criminal prosecution of two actors, the producer and director of the play The Beard.  Although the defendants raised constitutional objections to their prosecution, the Supreme Court decided the case on the narrow grounds that the obscenity statute at issue did not apply to theatrical productions.
