A CONICET researcher found fragments of the priceless incunabula in a library at Princeton University.

It could also be determined that its author was Alfonso de Palencia, one of the greatest humanist of the 15th century.  Incunabula are those books that were printed between the middle and the end of the 15th century; more precisely, between the time when Johannes Gutemberg invented the the printing press with movable type and the year 1501.  The possibility of finding a totally unkown incunabula is so rare that it is estimated that, with luck, it occurs once every fifteen years for each language, but whenever it happens it means a fact of great relevance for the field of the history book.
