Editio Princeps

As far as I know, the editio princeps of the Liber Genealogus is the edition of the Codex Taurinensis published at Paris by Christoph Pfaff in 1712. It can found on Google Books. The full title is Firmiani Lactantii Epitome Institutionum Divinarum ad Pentadium fratrem. For a German note about Pfaff, see Wikipedia.
