Behind the apparent diversity of subject matter in Giraudoux's plays there is a central unity, the persistence of the great Romantic theme of the search for a suprahuman ideal. Typically, the hero of a Giraudoux play is seeking some image of beauty, power, and mystery that lies beyond the range of human experience. But this ideal world, however attractive, has its opposite in the limited human world of daily existence with its own beauty, grace, and comfort. Moreover, each of these worlds has a negative aspect; the human world may be characterized by greed, hatred, and vulgarity just as the ideal may be cruel, inhuman, fatal. As a result, Giraudoux's plays are marked by a profound ambiguity and express deeply divided attitudes not only toward the suprahuman but toward its human opposite as well. The four tragic works from the great series of plays of the nineteen thirties form a natural group and, because the conclusions toward which they drive are at once desired and feared, they reveal this essential ambiguity more directly than any others. Judith, The Trojan War Will Not Take Place (Tiger at the Gates), Electra, and Ondine all show, by means of a dramatic image of destruction through a quest for the ideal, those central attitudes and concerns which characterize Giraudoux's art.
