Margarita Peña

[4] She received her bachelor's and master's degrees in Hispanic literature at the National Autonomous University of Mexico;[5] and her doctorate from El Colegio de México.

She served as a teacher at the undergraduate level for more than thirty years at the Faculty of Philosophy and Letters of the National Autonomous University of Mexico.

Her constant work in the Archivo General de la Nación gave her access to letters, sonnets, romances, declarations of prisoners, spells, and even a fragment of a treatise on palmistry.

The work that brings together a wide variety of these writings is called La palabra amordazada, and presents literature censored by the Mexican Inquisition during the colonial period.

The critical edition of the New Spanish songbook of the 16th century, Flores de baria poesía, is part of her work,[7] as is the novel, El amarre.
