Greek works, source by source
The Greek series needs saying work by work: Migne prints a Latin translation beside the Greek, and this edition translates from the Greek while using that Latin column only as a check.

Column numbers
Column references throughout follow the original Migne plates, not the
Garnier reprints, whose columns differ. A citation such as migne.app/pl/139/473a
resolves against the original.
