Late Neoplatonist systematic metaphysics

The Elements of Theology

A systematic and rigorous exposition of Neo-Platonic metaphysics, structured as a series of 211 propositions with demonstrations. Proclus presents a comprehensive cosmology describing emanation from the One through levels of being, including the henads (divine units), intellect, soul, and matter. Each proposition builds logically on previous ones, creating complete metaphysical system. Thomas Taylor's 1816 translation restored this foundational text to the English-speaking esoteric tradition. The work influenced Islamic philosophy, Christian theology, and Renaissance occultism.
