We know with certainty regarding Athenagoras, that he was an Athenian philosopher who had embraced Christianity, and that his Apology, or, as he styles it, "Embassy", was presented to the Emperors Aurelius and Commodus about a.d. 177. He is supposed to have written a considerable number of works, but the only other production of his extant is his treatise on the Resurrection. It is probable that this work was composed somewhat later than the Apology (see chap. xxxvi.), though its exact date cannot be determined. Philip of Side also states that he preceded Pantaenus as head of the catechetical school at Alexandria; but this is probably incorrect, and is contradicted by Eusebius. A more interesting and perhaps well-rounded statement is made by the same writer respecting Athenagoras, to the effect that he was won over to Christianity while reading the Scriptures in order to controvert them. Both his Apology and his treatise on the Resurrection display a practiced pen and a richly cultured mind. He is by far the most elegant, and certainly at the same time one of the ablest, of the early Christian Apologists.
