Christian Platonism or Augustinianism seems to be undergoing a kind of renaissance. Here are some books I have found interesting, in no particular order, with links. David C. Schindler,
Plato's Critique of Impure Reason;
Douglas Hedley,
Living Forms of the Imagination; William Riordan,
Divine Light: The Theology of Denys the Areopagite; C.F. Kelley,
Meister Eckhart on Divine Knowledge; Christian Moevs,
The Metaphysics of Dante's Comedy; Robert Bolton,
The Order of the Ages and
Self and Spirit; Adrian Pabst,
Metaphysics: The Creation of Hierarchy; John Rist,
What Is Truth?; Svetla Slaveva-Griffin,
Plotinus on Number; and Giovanni Reale,
Toward a New Interpretation of Plato [congenial with
Plotinus on Number, but
see critique].
