Many assumed she was Don Juan Caro de Mallén y Soto's sister, and that she was born in either Granada or Seville.
When she published Contexto de las reales fiestas madrilenas del Buen Retiro in 1637, she had already moved to Madrid.
El conde partinuplés[4] and Valor, agravio y mujer (Courage, Betrayal, and a Woman Scorned)[5][6] are the only two full-length plays by Caro de Mallén that are still known today.
Characters Leonor: A noblewoman who cross dresses as a man to regain her honor after being deceived by Don Juan.
Don Juan: An arrogant nobleman from Cordova, who assembles fallacious vows with high class women, like Estela, and manages to trick Leonor into falling into his "game of love."
Estela: An indecisive countess that must choose between multiple men only in the end to fall in love with an unexpected person.
Estela shows no romantic interest towards Don Juan nor Ludovico, but confesses her feelings for Leonardo who explains that he does not reciprocate her love.
Although based on a popular book of chivalry,[9] it also includes numerous echoes of Pedro Calderón de la Barca's plays, particularly those published in the first part of his works (1636).
She was known for writing dialogue that included single stanza verse shifts between characters that were made up largely of exchanges of metaphor.
Through her comedic plays Caro de Mallén made comments on the social and political realities of 17th century Spain.
Popular thematic ideas that are present in Caro de Mallén's work are revenge, honor, intrigue, and Love triangles.
