Sor Juana Inés de la Cruz, O.S.H. (English: Sister Joan Agnes of the Cross; 12 November 1648 – 17 April 1695), was a self-taught scholar and student of scientific thought, philosopher, composer, and poet of the Baroque school, and Hieronymite nun of New Spain, known in her lifetime as "The Tenth Muse", "The Phoenix of America", or the "Mexican Phoenix". Sor Juana lived during Mexico's colonial period, making her a contributor both to early Mexican literature as well as to the broader literature of the Spanish Golden Age. Beginning her studies at a young age, Sor Juana was fluent in Latin and also wrote in Nahuatl, and became known for her philosophy in her teens. Sister Juana educated herself in her own library, which was mostly inherited from her grandfather. After joining a nunnery in 1667, Sor Juana began writing poetry and prose dealing with such topics as love, feminism, and religion. Her criticism of misogyny and the hypocrisy of men led to her condemnation by the Bishop of Puebla, and in 1694 she was forced to sell her collection of books and focus on charity towards the poor. She died the next year, having caught the plague while treating her fellow nuns.
