There is more than one English translation of the Meditations or Thoughts of Marcus Aurelius, and Dio Cassius may be read in Foster's recent translation ; but Firmicus and the Codex Theodosianus have not been translated. The Notitia Dignitatum, an official list of all the posts in the administrative system of the late Empire, is translated in vol. II, no. 4, of Translations and Reprints of the University of Pennsylvania. The translation includes but one of the many interesting illustrations with which the Latin text is adorned and which may be examined in Seeck's edition (Berlin, 1876). The last book of The Metamorphoses of Apuleius (translated by E. H. Butler, 2 vols., Oxford, 1910) is rich in information concerning the spread of Oriental cults.
