BIBLIOGRAPHY
The Cambridge History of Later Greek and Early Medi-
aeval Philosophy, edited by A. H. Armstrong (Cam-
bridge, 1967; reprint 1970), gives a full account of Neo-
Platonism, its development, and its influence on early
medieval thought. Part I, by P. Merlan, deals with pre-
Plotinian Platonism; Part II, by H. Chadwick, with Philo
of Alexandria and the earliest Christian thinkers; Part III,
by A. H. Armstrong, with Plotinus; Part IV, by A. C. Lloyd,
with the later Neo-Platonists. The remaining four Parts, by
R. A. Markus, P. Sheldon-Williams, H. Liebeschütz, and
R. Walzer, are very largely concerned with Neo-Platonic
influences on Christian patristic and early medieval thought
in East and West, and on Muslim philosophy. All parts have
extensive bibliographies, including the principal editions
and translations of Neo-Platonic texts.
On Plotinus and his predecessors, see also Les Sources
de Plotin, Entretiens Hardt V (Vandoeuvres and Geneva,
1960); J. M. Rist, Plotinus: The Road to Reality (Cambridge,
1967), which includes a good bibliography. On Porphyry
see Porphyre, Entretiens Hardt XII (Vandoeuvres and
Geneva, 1966); and P. Hadot, Porphyre et Vietorinus, Vols.
I-II (Paris, 1968). On the later Neo-Platonists the most
important work in English besides A. C. Lloyd's contri-
bution to the Cambridge History referred to above is the
commentary of E. R. Dodds on Proclus, Elements of Theol-
ogy, 2nd ed. (Oxford, 1963). See also L. J. Rosàn, The Philos-
ophy of Proclus (New York, 1949), with extensive bibliogra-
phies; J. Trouillard, Le Néoplatonisme, Encyclopédie de la
Pléiade, Histoire de la Philosophie, I, Orient-Antiquité-
Moyen Age (Paris, 1969), pp. 886-935. Le Néoplatonisme,
ed. P. Hadot (Paris, 1971), is also valuable.
