Nebrija's Dictionarium

[pthajovs at UCHICAGO.EDU]

Has anyone done historical work on the copy of Nebrija's Dictionarium in the
Newberry Library (Ayer ms. 1478), which adds Nahuatl to the Spanish and Latin
entries?  According to the Newberry's records, it probably dates to 1540.  At
first glance, some entries (at least the Spanish entries) parallel Molina's 1571
dictionary.  Newberry's catalog states that it may be from Sahagún's collection.
 So, a Tlatelolco provenence seems probable, at the least.  Can anyone share
more information on this?  I'm especially interested in Nebrija's Latin source,
and what a comparison of the ms. with Molina may tell us about the formation of
Molina's lexicon.  Thanks.
