Proclus' Elements of Theology is a concise summa of the Neoplatonic system in its fully developed form; and for the student of late Greek thought second in importance only to the Enneads of Plotinus. Professor Dodds has provided a critical text based on a personal examination of some forty manuscripts, together with an English translation and a philosophical and linguistic commentary. First published in 1933, this second edition includes an Appendix of Addenda et Corrigenda and is widely regarded and respected as the definitive edition of the text today.
