The Six books of Proclus, the Platonic successor, on The Theology of Plato (Greek: ΠΕΡΙ ΤΗΣ ΚΑΤΑ ΠΛΑΤΩΝΑ ΘΕΟΛΟΓΙΑΣ; Latin: Theologia Platonica; Alternate English Title: Platonic Theology) to which a Seventh book is added by the translator, Thomas Taylor, in order to supply the deficiency of another book on this subject, which was written by Proclus, but since lost. According to the 1995 Prometheus Trust edition Book 3 Chapter 1 of this translation contains Chapters 1-4 from the original Greek, Chapter 2 contains the Greek chapters 5-6 and Chapter 3 contains the Greek Chapters 7-8. Thereafter, the translated and Greek chapters match beginning at Chapter 9. A quotation from Proclus is included on the cover of Harmonices Mundi Liber I despite the fact that Johannes Kepler's mother had been recently accused of witchcraft and threatened with torture. - Summary by Geoffrey Edwards
