Writing Teresa: The Saint from Avila at the fin-de-siglo examines the Teresa de Jesus boom of roughly 1880-1930 and offers an in-depth study of five major Spanish participants in the turn-of-the-twentieth-century explosion of literary treatments of St. Teresa. This historical period’s interest in the Saint from Avila relates to popularization and nationalization of aspects of Catholicism, technological advances, a modernist fascination with saintly heroes, the search for new Spanish identities, and the evolving role of women writers and intellectuals. Teresa was mysticism in its historical context, energy in a time of doubt, the possibility of reconciling science and spirituality, a new vision for writing, and a maternal figure linked to the religion of the past for those who had lost the faith of their childhood.
