The Enigmas offered to the Discrete Intelligence of the Sovereign Assembly of the House of Pleasure by her Most Solicitous and Devoted Sister Juana Inés de la Cruz, Tenth Muse (Lisbon, 1695) is an unpublished work considered minor, whose finding Enrique Martínez López made public in 1968 (reprinted in 1970) and Antonio Alatorre reedited in 1994 (reprinted in 1995). The Enigmas, addressed to a feminine public, both courtly and learned, including the Countess of Paredes and the Duchess of Aveiro, are an interpretive key to Sor Juana’s entire oeuvre. As in her love lyric, this very little studied piece reconfigures the symbol as well as the role of woman within Petrarchan rhetoric, adding to it an unprecedented epistemological dimension
