Gregory of Nyssa's work is commonly cited both as "De hominis opificio" and "De opificio hominis". I would have thought that the latter is better. But both have been in use for centuries. The work itself is in Greek. Curiously, some secondary literature quotes both titles on the same page, e.g.: https://books.google.co.nz/books?id=uiiwCQAAQBAJ&pg=PA49#v=onepage&q&f=false https://books.google.co.nz/books?id=6KgnBwAAQBAJ&pg=PA431#v=onepage&q&f=false Which is preferable? Which is original? I would appreciate any help.
