Seven volumes of what appears to have been an eight-volume publication. The title pages number the parts Prima, Secunda, Tertia, Quarta, Sexta, Septima and Index. Thus apparently lacking part five. 24mo (5' X 3-1/2') in full vellum. Each volume is entirely intact although with flaws. In some cases the text block is beginning to separate from the spine, pastedowns are separating from the boards, and the vellum is heavily chipped on two volumes. The text blocks however are quite nice, with headpieces and initials, and virtually no foxing or other damage.
