These two volumes consist of a critical edition and English translation of the two earliest known Armenian sets of scholia on the Heavenly Hierarchy of Dionysius the Areopagite. Composed in the monastic schools of Erznka in the late thirteenth century, these scholia provide significant insight into how the Heavenly Hierarchy in particular, and Armenian translations of Greek texts in general, were understood by Armenian scholars in the Middle Ages. This editio princeps of the scholia represents a rare critical edition of a native Armenian composition from the medieval period. In addition to the text and translation, these volumes include a textual commentary as well as a critical collation and English translation of a number of scholia from the Armenian version of the Greek scholia on the Heavenly Hierarchy.
