In England, where practice ran ahead of theory, the situation was quite different. In the sixteenth century, "tragicomedy" meant the native sort of romantic play that violated the unities of time, place, and action, that glibly mixed high- and low-born characters, and that presented fantastic actions. These were the features Philip Sidney deplored in his complaint against the "mungrell Tragy-comedie" of the 1580s, and of which Shakespeare's Polonius offers famous testimony: "The best actors in the world, either for tragedy, comedy, history, pastoral, pastoral-comical, historical-pastoral, tragical-historical, tragical-comical-historical-pastoral, scene individuable, or poem unlimited: Seneca cannot be too heavy, nor Plautus too light. For the law of writ and the liberty, these are the only men." Some aspects of this romantic impulse remain even in the work of more sophisticated playwrights: Shakespeare's last plays, which may well be called tragicomedies, have often been called romances.
