Sister Ana de la Trinidad —Ana Ramírez de Arellano— (Alcanadre, 1577 - Calahorra, 1613) is a great unknown of Spanish letters, despite being one of our most notable writers. Daughter of one of the most influential families of her time - one of the various branches of the Ramírez de Arellano -, her father was the Lord of Alcanadre, Ausejo and Murillo de Río Leza and her uncle, Lord of the Cameros. Woman of great religious concerns, well-trained and very fond of reading, she acquired important knowledge of music, Latinidad in a self-taught way
and arithmetic.
At the beginning of the 17th century, she entered the convent recently created by the Carmelite order in Calahorra, under the direction of the writer and abbess Cecilia del Nacimiento, who guided her and taught her the poetic forms of mystical literature.
Ana died at the young age of thirty-six, having foreseen the day of her death herself.
