innovation, around 515 — thus suggesting a later date for the Corpus. It is often suggested that because Dionysius seems to eschew divisive Christological language, he was probably writing after the Henoticon of Zeno was in effect, sometime after 482. It is also possible that Dionysius eschewed traditional Christological formulae in order to preserve an overall apostolic ambience for his works, rather than because of the influence of the Henoticon. Also, given that the Henoticon was rescinded in 518, if Dionysius was writing after this date, he may have been untroubled by this policy. In terms of the latest date for the composition of the Corpus, the earliest datable reference to Dionysius' writing comes in 528, the year in which the treatise of Severus of Antioch entitled Adversus apologiam Juliani was translated into Syriac — though it is possible the treatise may originally have been composed up to nine years earlier. Another widely cited latest date for Dionysius' writing comes in 532, when, in a report on a colloquy held between two groups (orthodox and monophysite) debating the decrees of the Council of Chalcedon, Severus of Antioch and his monophysite supporters cited Dionysius' Fourth Letter in defence of their view. It is possible that pseudo-Dionysius was himself a member of this group, though debate continues over whether his writings do in fact reveal a monophysite understanding of Christ. It seems likely that the writer was located in Syria, as revealed, for example, by the accounts of the sacramental rites he gives in The Ecclesiastical Hierarchy, which seem only to bear resemblance to Syriac rites. Authorship The author pseudonymously identifies himself in the corpus as "Dionysios", portraying himself as the figure of Dionysius the Areopagite, the Athenian convert of Paul the Apostle mentioned in Acts 17:34. Various legends existed surrounding the figure of Dionysius, who became emblematic of the spread of the gospel to the Greek world. A tradition quickly arose that he became the first bishop of Cyprus or of Milan, or that he was the author of the Epistle to the Hebrews; according to Eusebius, he was also said to be the first bishop of Athens. It is therefore not surprising that that author of these works would have chosen to adopt the name of this otherwise briefly mentioned figure. The authorship of the Dionysian Corpus was initially disputed; Severus and his party affirmed its apostolic dating, largely because
