The Elements of Theology (Ancient Greek: Στοιχείωσις θεολογική, romanized: Stoicheiōses Theologikē) is a work on Neoplatonic philosophy written by Proclus (c. 412–485).

The propositions can be informally halved into dual parts, the first, establish the unity of the many in the One, causality, participation, gradiation, procession, infinitude and eternity.

[2] An Arabic adaptation of the Elements of Theology was made in the 9th century, called the Kitāb al-Īḍāḥ fī al-khayr al-maḥḍ ("The Book on the Explanation of the Pure Good").

[4] Falsely attributed to Aristotle, this work was in turn translated into Latin in the 12th century by Gerhard of Cremona under the name Liber de causis.

[5] Another way in which the Elements of Theology found its way into medieval Aristotelian philosophy is through the portions of the book that were interspersed in Arabic translations of works by the Peripatetic philosopher Alexander of Aphrodisias.
