A study of Benavides's Memoriales in Spanish is made difficult because only the 1630 Memorial has a Spanish edition accompanying it. The 1634 Memorial has been published only as a translation into English. Despite this insufficiency, comparing the two translations suffices to demonstrate that the term "revision," if it means "correcting" or "improving," does not aptly describe the textual relationship between the two. Furthermore, the remaining physical evidence of the 1634 Memorial makes it seems unlikely that it was ever published or, more importantly, that it ever reached Pope Urban VIII to whom it was directed.
