The treatise that gives Praxeas his entire existence — everything known about him comes from an opponent writing to refute him, including his name, which may be a nickname rather than a name. It is also where the Latin vocabulary of the Trinity is first worked out: one substance, three persons. Printed in ANF vol. 3, which this project does not hold: cited, never quoted.
