Episode 178: Stephen A. Cooper on Marius Victorinus and Latinate Christian Platonism

We are delighted to discuss Marius Victorinus, an extraordinary Christian Platonist of the third-fourth centuries writing in Latin, with Stephen A. Cooper.

We discuss the basics of what we know of Victorinus’ life, and his extraordinary conversion to Christianity, through which he imported the ensemble of his previous intellectual commitment – to a Plotinian or Porphyrian type of Late Platonism, with the extra religious dimension which comes from engagement with the Chaldæan Oracles – into his Christianity. We then survey his surviving (and otherwise) literary works, from the rhetorical, grammatical, and logical works of his trad period to the Christian works, which include a number of philosophic defences of Nicene trinitarianism on philosophic, Platonising grounds, and a series of in-depth commentaries on the letters of Paul of Tarsus, the earliest such known in Latin. He also made some crucial, lost translations from ‘the Platonists’ – Plotinus and Porphyry – into Latin.

We get into some of the theological and political background of the ‘Arian controversy’ in which Victorinus played a major rôle on the trinitarian side.

In the end we discuss Victorinus’ Nachleben, but the discussion is interwoven with discussion of his thought. What emerges is a truly, but subtly, esoteric Christian/Platonist synthesis wherein Plotinus and the Chaldæan Oracles are sensible texts to cite to make doctrinal points, and, alongside revelation, the Christian has another potential avenue for acquiring divine knowledge, namely noetic ascent.

Works Cited in this Episode:


Augustine on Victorinus: Conf. 7.9.13 (that MV translated libri Platonicorum); Conf. 8.2.3–8.4.9 gives the whole story from Simplicianus, mixed with some of Augustine’s reflections. Also Conf. 8.5.10 tells how MV resigned his chair after Julian’s “school law” (Cod. theod. 13.3.5) of 17 June 362 CE.

Jerome on Victorinus: in his On Famous Men, Jerome adds the detail that he was born in Roman Africa (“natione Afer”) and that he became a Christian “in extreme old age” (“in extrema senectute” (Vir. ill. 101). The same passage also says that he had written “adversus Arium libros valde obscuros” (“very incomprehensible books against Arius”)

Jerome’s states (in Ruf. 1.16) that as a student he read a commentary by Victorinus “on Cicero’s dialogues”; this probably refers to his work on his Topics, which in ancient discourse was lumped with Cicero’s philosophical dialogues.

Victorinus’ grandaughter’s tombstone: CIL 6.31934. The inscription indicates she had married a “vir clarissimus” (a man of the lowest level of the senatorial order). For the inscription, translation, and discussion, see Pierre Hadot. Marius Victorinus: Recherches sur sa vie et ses oeuvres. Études Augustiniennes, Paris, 1971, pp. 16–17.
