Aristides of Athens, a contemporary of Quadratus, is called by Eusebius in his Chronicle “a philosopher” (nostri dogmatis philosophus Atheniensis). Eusebius does not quote his work, perhaps because he did not himself possess a copy, perhaps because it contained no historical matter suitable to his purpose. He does not mention him again (the Aristides, the friend of Africanus, of Bk. I. chap. 7 and of Bk. VI. chap. 31, lived a century later), and his Apology is quoted by none of the Fathers, so far as is known. Vague and worthless traditions of the Middle Ages still kept his name alive, as in the case of Quadratus, but the Apology itself disappeared long ago, until in 1878 a fragment of an Apology, bearing the name of “Aristides, the Philosopher of Athens,” was published by the Mechitarists from a codex of the year 981. It is a fragment of an Armenian translation of the fifth century; and although its genuineness has been denied, it is accepted by most critics, and seems to be an authentic fragment from the age of Hadrian. See especially Harnack, ibid. p. 109 sq., and again in Herzog, 2d ed., Supplement Vol. p. 675–681; also Schaff, Ch. Hist. II. p. 709.
