Plunka, Gene A. Peter Shaffer: Roles, Rites, and Rituals in the Theatre. Rutherford, N.J.: Fairleigh Dickinson University Press, 1988. Disappointing in the absence of coverage of later plays but strong on The Royal Hunt of the Sun, Equus, and Amadeus. This work is part sociology and part mythology, and it is fed by an interview with the playwright in 1986. It contains occasional insights but is generally too scholarly to get at the essence of Shaffer’s examination of the ways of God to humankind.
Taylor, John Russell. Peter Shaffer. London: Longman, 1974. Provocative essay on Shaffer’s contributions through Equus that sees detachment in the play and “a tendency to analyze emotions without too far engaging himself in them as a dramatist.”
