It has been denied that Rojas Zorrilla belongs to Calderón’s school, and no doubt he was much more than an obsequious pupil. Yet he was clearly affiliated to the school. He belonged to the same social class as Calderón; he was seven years younger, and must have begun writing for the stage just when it became evident that Calderón was destined to succeed Lope de Vega in popular esteem; and, moreover, he actually collaborated later with Calderón in _El Monstruo de la fortuna_. It is hard to believe that Calderón, at the height of his reputation, would condescend to collaborate with a junior whose ideals differed from his own. No such difference existed: as might be expected from a disciple, Rojas Zorrilla is rather more Calderonian than Calderón. Out of Spain he is usually mentioned as the author of _La Traición busca el castigo_, the source of Vanbrugh’s _False Friend_ and Lesage’s _Le Traître puni_; but, if he had written nothing better than _La Traición busca el castigo_, he would not rise above the rank and file of Spanish playwrights. His most remarkable work is _García del Castañar_, a famous piece not included in either volume of the plays issued by Rojas Zorrilla himself. The natural explanation would be that it was written after 1645, and this is possible. Yet it cannot be confidently assumed. As we have already seen, _La Estrella de Sevilla_ is not contained in the collections of Lope’s plays. Plays were not included or omitted solely on their merits, but for other reasons: because they were likely to please ‘star’ actors, or because they had failed to please a particular audience.
