The Reply of the Master Abammon to the Letter of Porphyry to Anebo and the Solutions to the Difficulties Raised Therein (Ἀβάμμωνος διδασκάλου πρὸς τὴς Πορφυρίου πρὸς Ἀνεβὼ ἐπιστολὴν ἀπόκρισις καὶ τῶν ἐν αὐτῇ ἀπορημάτων λύσεις - Abammônos didaskalou pros tês Porphuriou pros Anebô epistolên apokrisis kai tôn en autê aporêmatôn luseis) of the divine Iamblichus. Known since the translation of Marsilio Ficino as De Mysteriis (De Mysteriis Aegyptiorum Chaldaeorum Assyriorum) or simply On the Mysteries in English.

The Chaldean Oracles (Λόγια Χαλδαϊκά - Logia Chaldaika) of Julianus the Theurgist, surviving in fragments as collected by Patrizzi, Taylor, Cory, Des Places and others along with the classic Byzantine commentaries of Michael Psellus and Georgius Gemistos Plethon.

On the Sacred Art of the Greeks  (Περι της ἱερατικης τεχνης - Peri tês hieratikês technês) of Proclus. Also known as De Sacrificio et Magia from the Latin version of Ficino.

The Mithras Liturgy from the famed magical codex, Papyrus 574 kept in the Bibliothèque Nationale de France. This work is considered by most scholars of late Platonic hieratic praxis (Shaw, Majercik etc) to be illustrative of the types of practices that would have been familiar to the divine Iamblichus and other practitioners of Theurgy.

Proclus or On Happiness  (Προκλος ἤ περι εὐδαιμονιας - Proklos ê Peri Eudaimonias) by Marinus of Samaria is the main source of our knowledge of the life of Proclus and contains many valuable references to his personal spiritual practice and Theurgic accomplishments.

Seven Hymns of Proclus. Hymns to Helios, Aphrodite, the Muses, All the Gods, the Lycian Aphrodite, Hekate and Janus, and Athena. Text in Greek with Roman transliteration.
