One other note regarding Bishop de Landa...
"He is the author of the Relación de las Cosas de Yucatán in which he catalogues the Maya language, religion, culture and writing system. This manuscript was written around 1566 on his return to Spain; however, the original copies have long since been lost. The account is known to us only as an abridgement, which in turn had undergone several iterations by various copyists. The extant version was produced around 1660, and was discovered by the nineteenth centuryFrench cleric Charles Etienne Brasseur de Bourbourg in 1862. Brasseur de Bourbourg published the manuscript two years later in a bilingual French-Spanish edition, entitled Relation des choses de Yucatán de Diego de Landa."
Great book by the way - I highly recommend it!
Nostradamus died in 1566, so there well may have been interaction, as well as the fact that some of the friars who returned to Europe might have hooked up with Nostradamus.
