Three more goodies to link to:
I've
uploaded to my site two PDFs, one is the substitution cypher written about by Venerable Bede (under 8th century) and the other is a rather large PDF with the manual alphabets of
Thesaurus Artificiosae Memoriae (1579),
Refugium Infirmorum (1593),
Reducción de las letras y arte para enseñar a hablar a los mudos (1620),
Didascalocophus (1680),
Digiti Lingua (1698), modern ASL and modern BANZSL in a big table for easy comparison. (Stuffed in under '16th century' although I'm not sure that's the right place.)
Yes, a lot of it is 17th century, but I think it needs to be there -- there
are differences between de Yebra and Bonet's alphabets, and there are differences between them and modern ASL, even though
so many publications imply they are all the same. Dalgarno and
Digiti Lingua are included because I'm horribly biased and think it's important to know where BSL-derived fingerspelling seems to have originated.
The third link, is GoogleBooks has put the
entirety of
Libro llamado Refugium infirmorum, muy útil y provechoso para todo género de gente, en el cual se contienen muchos avisos espirituales para socorro de los afligidos enfermos, y para ayudar a bien morir a los que están en lo último de su vida; con un alfabeto de San buenaventura para hablar por la mano.(Book called refuge of the sick, very useful and beneficial for all kinds of people, in which is contained much spiritual advice for assistance of distressed sick persons, and for helping those who are at the end of their lives to die well; with Saint Bonaventure's alphabet to speak by the hand)
online, and can be downloaded as a PDF.
