Marcus Minucius Felix was one of the earliest of the Latin apologists for Christianity.
Of his personal history nothing is known, and even the date at which he wrote can be only approximately ascertained as between 150 and 270 AD. Jerome's De Viris Illustribus #58 speaks of him as "Romae insignis causidicus," but in that he is probably only improving on the expression of Lactantius who speaks of him as "non ignobilis inter causidicos loci."
He is now exclusively known by his Octavius, a dialogue on Christianity between the pagan Caecilius Natalis and the Christian Octavius Januarius.
The Octavius is admittedly earlier than Cyprian's Quod idola dei non sint, which borrows from it; how much earlier can be determined only by settling the relation in which it stands to Tertullian's Apologeticum.
