BIBLIOGRAPHY.--The editions of Robert Etienne (Stephanus) (1551); H. Sylburg (1593); F. Morel (1615); Prudentius Maranuis (1742) are superseded by J. C. T. Otto, _Justini philosophi et martyris opera quae feruntur omnia_ (3rd ed. 5 vols., Jena, 1876-1881). This edition contains besides the _Apologies_ (vol. i.) and the _Dialogue_ (vol. ii.) the following writings: _Speech to the Greeks_ (_Oratio_); _Address to the Greeks_ (_Cohortatio_): _On the Monarchy of God_; _Epistle to Diognetus_; _Fragments on the Resurrection and other Fragments_; _Exposition of the True Faith_; _Epistle to Zenas and Serenus_; _Refutation of certain Doctrines of Aristotle_; _Questions and Answers to the Orthodox_; _Questions of Christians to Pagans_; _Questions of Pagans to Christians_. None of these writings, not even the _Cohortatio_, which former critics ascribed to Justin, can be attributed to him. The authenticity of the _Dialogue_ has occasionally been disputed, but without reason. For a handy edition of the _Apology_ see G. Kruger, _Die Apologien Justins des Martyrers_ (3rd ed. Tubingen, 1904). There is a good German translation with a comprehensive commentary by H. Veil (1894). For English translations consult the "Oxford Library of the Fathers" and the "Ante-Nicene Library." Full information about Justin's history and views may be had from the following monographs: C. Semisch, _Justin der Martyrer_ (2 vols., 1840-1842); J. Donaldson, _A Critical History of Christian Literature and Doctrine_, vol. 2 (1866); C. E. Freppel, _St Justin_ (3rd ed., 1886); Moritz von Engelhardt, _Das Christentum Justins des Martyrers_ (1878); T. M. Wehofer, _Die Apologie Justins des Philosophen und Martyrers in litterarhistorischer Beziehung zum ersten Male untersucht_ (1897); Alfred Leonhard Feder, _Justins des Martyrers Lehre von Jesus Christus_ (1906). On the critical questions raised by the spurious writings consult W. Gaul, _Die Abfassungsverhaltnisse der pseudo-justinischen Cohortatio ad Graecos_ (1902); Adolf Harnack, _Diodor von Tarsus. Vier pseudo-justinische Schriften als Eigentum Diodors nachgewiesen_ (1901). (G. K.)
