Given that the title page labels these as "sacred" songs, and in order to be sacred, it needs to be based on a sacred text of some sort, it is possible (perhaps likely) that these are arrangements of pre-existing sacred songs. Without the two parts that would give melody line, and without any labels on the actual pieces, it is very hard to tell. The tagging may have to be corrected if this can ever be ascertained.
