The Eagle of the Apocalypse refers to St. John of Patmos, the putative writer of the last book of the New
Testament, the Apocalypse (i.e., Revelations). From the 2nd century C.E. until the 20th century, Christian exegetes generally conflated John the Presbyter with both John of Patmos (the Greek island on which a person named John is said to have received the divinely inspired visions set forth in the Book of the Apocalypse) with John the evangelist and John the author of the so-called Johannine epistles (John I, II, III).

César Meneses. Most likely, the Bishop is referring to the aristocratic Portuguese Churchman and Political activist,
Sebasti o César de Meneses (? – 1672). He earned a doctorate in canon law from the Jesuit University of Coimbra,
Portugal in 1628, when he published a book in Latin on Church hierarchs. Throughout his life he was an official of the Portuguese Inquisition (Santo Ofício). He participated in the Portuguese independence revolution against Spain beginning in 1640, and in 1642 he was named Bishop of Oporto, although he never actually took up the position. In
1649, he publish a book on political theory (Suma Política) that a modern critic (Aubrey Bell) called "notable for its logical precision and clarity and concision of form." After suffering a decade of political vicissitudes, he became
Grand Inquisitor in 1663. This same year, he published a work on ingratitude, Sugillatio Ingratitudinis, which is not doubt the book the Bishop of Puebla had in mind when writing this letter to Sor Juana. The last ten years of his life he was condemned to internal exile several times. He is buried in the Discalced Carmelite
