Proclus - Elements of Theology

The Elements of Theology (ΣΤΟΙΧΕΙΩΣΙΣ ΘΕΟΛΟΓΙΚΗ) was written by the Greek Neoplatonist philosopher Proclus (ΠΡΟΚΛΟΣ) and translated by Thomas Taylor who named his youngest son Thomas Proclus Taylor. This book consists of 211 propositions, each followed by a proof, beginning from the existence of the One (divine Unity) and ending with the descent of individual souls into the material world. Saint Thomas Aquinas recognized that the Liber de Causis (Book of Causes), which had been attributed to Aristotle, was actually a summary of the Elements of Theology, likely written by an Arabic interpreter. — Summary adapted from Wikipedia by Geoffrey Edwards
