A number of works of Apolinarius have been preserved by many, and the following have reached us: the Discourse addressed to the above-mentioned emperor, five books Against the Greeks, On Truth, a first and second book, and those which he subsequently wrote against the heresy of the Phrygians, which not long afterwards came out with its innovations, but at that time was, as it were, in its incipiency, since Montanus, with his false prophetesses, was then laying the foundations of his error.
