Proclus(412–485 CE)

Commentaries on Euclid, by T. Taylor

The Dial's edition: London, 1788

A Neoplatonic reading of Euclid that treats geometry as intellectual training for metaphysics, using the first book of the Elements to explain how mathematical reasoning lifts the mind toward first principles. Translated by Thomas Taylor.

Commentaries on the Timæus of Plato, by T. Taylor

The Dial's edition: London, 1820

Proclus's expansive, line-by-line Neoplatonic interpretation of Plato's Timaeus, presenting the doctrines of cosmos, soul, time, and the divine craftsman, and preserving a 'treasury' of Pythagorean and Platonic natural philosophy. Translated by Thomas Taylor.

Fragments by T. Taylor

Full title: The fragments that remain of the lost writings of Proclus, tr. by T. Taylor

Ten Doubts, &c

The Dial's edition: London, 1833

Two focused works: one tackles classic aporiae about providence, fate, and freedom through ten 'doubts' and their solutions; the other develops Proclus's account of how evil can exist in a world ordered by the Good. Translated by Thomas Taylor.

Theology, by T. Taylor

Full title: The six books of Proclus, the Platonic successor, on the theology of Plato

The Dial's edition: London, 1816

A systematic map of Platonic theology (the hierarchy of gods and divine orders as Proclus reconstructs it from Plato), with an added 'seventh book' to supply a lost portion, plus Taylor's translation of the Elements of Theology and additional related treatises/extracts. Translated by Thomas Taylor.
