There is a difficulty about this. The Bollandists maintain that she went to the monastery of the Incarnation in the year 1533. On the other hand Ribera, her most accurate biographer--with whom Fra Jerome agrees,--says that she left her father's house in 1535, when she was more than twenty years of age; Yepes, that she was not yet twenty; and the Second Relation of the Rota, that she was in her twentieth year. The Bull of Canonisation and the Office in the Breviary also say that she was in her twentieth year, that is, A.D. 1534. The Chronicler of the Order differs from all and assigns the year 1536 as the year in which she entered the monastery.
