The Christian religion figures prominently in the vast output, both discursive and imaginative, of Miguel de Unamuno. Unamuno studied nineteenth-century biblical scholarship closely, especially that of the Liberal Protestant school, but its influence did not dictate his direction. Without fully accepting the traditional Roman Catholic interpretation of the New Testament, what position vis-a-vis Jesus of Nazareth did Unamuno occupy himself? How did he see this figure from the Palestine of two thousand years ago, which has been so influential in western culture? What role does the Nazarene play in Unamuno’s work? What does the presence of Jesus tell us about the Basque writer’s idiosyncratic and combative religious views that drew the opprobrium of the Spanish Church hierarchy? This study focuses on the figure of Jesus of Nazareth as he appears in Unamuno’s writings – including The Tragic Sense of Life, The Christ of Velázquez, The Agony of Christianity, and San Manuel Bueno, mártir.
