Elements of theology‏

The Elements of Theology (Ancient Greek: Στοιχείωσις θεολογική, romanized: Stoicheiōses Theologikē) is a work on Neoplatonic philosophy written by Proclus (c. 412–485). Conceived of as a systematic summary of Neoplatonic metaphysics, it has often served as a general introduction to this subject. It was widely influential during the Middle Ages, especially through its 9th-century Arabic adaptation Kitāb al-Īḍāḥ fī al-khayr al-maḥḍ ("The Book on the Explanation of the Pure Good"), known in Latin as Liber de causis or "Book of Causes", which was falsely attributed to Aristotle. Proclus' work itself was first translated into Latin in 1268 by William of Moerbeke as Elementatio Theologica.
