The second of Lorca"s great trilogy of rural dramas, Yerma is a concentrated blend of contrasting moods through which Lorca charts the increasingly destructive obsession of a childless young country wife, and probes the darker zones of human fears and desires. The play"s rich mode of expression- a powerful combination of verbal, visual and auditory images and rhythms- is also geared to celebrating sexual attraction and fertility, creation and procreation.
