Dionysius the Areopagite
The fame of Stephen as a writer rests on his identification with the author of a treatise which survives in a single Syriac manuscript ("Brit. Mus. Add. MSS." 7189, written mainly in the 13th century), The book of Hierotheus on the hidden mysteries of the house of God. The work claims to have been composed in the 1st century AD, by a certain Hierotheus who was the disciple of Saint Paul and the teacher of Dionysius the Areopagite. But, like the works which pass under the name of Dionysius, it is undoubtedly pseudonymous, and most Syriac writers who mention it attribute it to Stephen. The author of the "Book of Hierotheus" is sometimes referred to as Pseudo-Hierotheus as his follower, Dionysius the Areopagite, is called Pseudo-Dionysius the Areopagite to differentiate them from the biblical figures.
