 King Philip IV of Spain, who was a secular Dominican himself, appeared to Monteagudo after his death in 1665 and asked for her intercession while later revealing to her that he had entered Heaven three days after his death following her prayers.She admired and was devoted to Saint Nicholas of Tolentino and beheld a vision of the Blessed Virgin Mary, the saint, and a legion of angels where the saint showed her purgatory.The nun died in 1686 and her remains were interred in the convent where she resided for most of her life.
