[Sca-cooks] Need (international) copyright advice

[Robin Carroll-Mann]

Forgive the cross-posting; I'm trying to query all the people who are
most likely to have an answer for me.

I just received a book that I ordered as a Christmas gift for myself.
It's "Regalo de la vida humana", a 16th century health and cooking
manual.  The author was an official of the Spanish Kingdom of Navarre.
 He did not complete the book before his death, and it was never
published until a few years ago.  The original manuscript -- the only
existing copy -- belongs to the National Library of Austria.  They
gave a high quality facsimile to the government of the Spanish
Province of Navarre, which commissioned the book I received today.

It's in two volumes.  The first volume is a facsimile.  The second
contains a transcription, as well as essays and notes on the work.
There are two copyright notices on the book: one for the National
Library of Austria and one for the Government of Navarre.

My question is this: if I translate some of the recipes and post those
translations on email lists and/or my website, am I violating
copyright?  (I'm assuming that I will NOT post the text of the
original Spanish.)  This is rather different than other period
cookbooks I've worked from, as those were published in period, and
there are digital and print copies available from many different
sources.  In this case, there is only one possible source for the
material.

I am in the U.S., but as both copyright holders are European, I assume
that EU laws and regulations apply.  I would appreciate knowledgeable
advice on this matter.  Perhaps I'm worrying about nothing, but I'd
rather know for sure.  At present, I only wish to translate and test
recipes, but I could envision eventually teaching a class at Pennsic.
I'd certainly want to know where the legal lines were drawn before
preparing a handout.
