Secretum is a trilogy of dialogues in Latin written by Petrarch sometime from 1342 to 1353, in which he examines his faith with the help of Saint Augustine, and "in the presence of The Lady Truth". Secretum was not circulated until some time after Petrarch's death, and was probably meant to be a means of self-examination during "the crisis of his middle years" more than a work to be published and read by others.
