Gothaer "Theater-Kalender" von 1777 über das Wiener Hofburgtheater:

Emperor Joseph is the Protector of this stage [i.e., of the Hofburgtheater]. Nothing escapes his attention and care for its improvement. The Monarch is convinced that a good national theatre has a very close and important influence on the character, morals and taste of his people. … No German stage better observes what is customary and decent. Taste keeps watch over the choice of plays, censorship over morals.
