Isagoge
Translation, introduction and notes by Edward W. Warren. MST 16. 1975. 65 pp. ISBN 978–0–88844–265–9 • $11.50
Porphyry’s Isagoge, or Introduction to the Categories of Aristotle, has exercised an amazing influence on the course of Western philosophy. A brief, modest work, designed to help a Roman senator grapple with Aristotle’s difficult concepts, the Isagoge became the first text that any aspiring philosopher confronted in his formal education; logic was the foundation of philosophical training and the Isagoge was the introduction to logic.

Philip the Chancellor’s Theology of the Hypostatic Union
Studies and Texts 32. 1975. 234 pp. ISBN 978-0-88844-032-7
For the theology of the Hypostatic Union (the union of the Son of God with the human form), the early thirteenth century was decisive, because in that period theologians resolved debates about three opinions on the subject that had divided earlier schoolmen. This volume examines the thought of Philip the Chancellor (ca. 1170–1236).

The Life of Cola di Rienzo is an anonymous eye-witness biography of Cola di Rienzo, a romantic visionary who led a popular revolution against the rapacious and tyrannical barons of medieval Rome.
