This analysis, written in Spanish, compares the use of violence in four of Castro's dramas with its use in their sources and in the works of other Golden Age authors. Chapter II investigates the manner in which the plays based on Greek myths compare with the original stories and with the ancient Classical theater. Each of the four following chapters compares one of Castro's plays to contemporary works with the same plot. The conclusion indicates that Castro's plays do not show an extraordinary use of violence. In some instances Castro demonstrates more restraint than the other dramatists. Thus, Castro, as a typical author of his epoch, does not deserve his reputation for writing excessively violent works.
