Clement of Alexandria's Works in Translation
G. W. Butterworth (translator), Clement of
Alexandria: Exhortation to the Greeks, The Rich Man's Salvation, To
The Newly Baptized (LOEB Classical Library 92) (Cambridge, MA: Harvard University Press, 1999) ISBN: 0674991036
A nice pocket sized hardback. Ideal for the busy commuter seeking late 2nd century inspiration! Especially good if you know (even a little) Greek, as the texts are printed with the Greek on the left hand page and the English translation on the right. The translation was made in 1919, so although dated in places it does make for easier reading than the versions in the Ante-Nicene Fathers series (see below).
A. Roberts and J. Donaldson (editors), The
Ante-Nicene Fathers, Volume 2: Fathers of the Second Century:
Hermas, Tatian, Athenagoras, Theophilus, and Clement Of Alexandria
(Entire)
Includes all of Clement's works - The Exhortation (Protreptikos), The Instructor (Paedagogus), The Miscellanies (Stromateis), Who is the Rich Man that Shall be Saved? (Quis Dives Salvetur). However, it is written in 1880's English which (combined with Clement's natural style) often makes it hard work to read.
