Sor Juana was regarded as an intellectual prodigy when she entered the court of the Marquise de Mancera, the viceroy of New Spain, at age 16. She served as a handmaiden to the Marquise’s wife, Leonor Carreto. Sor Juana was a reputed beauty. Some say she had her share of marriage offers, while others believe she was not an eligible candidate for marriage due to her illegitimacy. Sor Juana continued to impress the court—male and female alike—with her intelligence and education. At age 20, she left court unmarried to join a convent.
