The important early Jesuit Pedro de Ribadeneyra (1526-1611) has the distinction of having been a biographer of men, a biographer of women, an autobiographer, and the subject of biography. As such he and his texts seem particularly apt subjects for study given the current interest by scholars in a number of disciplines in the various forms of “life-writing“ produced so abundantly in the early modern period. In this essay I briefly examine Ribadeneyra's most famous biography, that of his mentor Ignatius Loyola, as well as two little-known and virtually unstudied texts: his Life of the pious laywoman Estefanía Manrique de Castilla and his autobiography or Confessions. I focus upon the ways in which he treated issues of authority and obedience in constructing as exemplary the lives of these three Spanish nobles and explore his strategies for enlisting life-writing in the campaign for a renewed, activist Catholicism.
