In the aftermath of John Chrysostom's deposal by the Synod of the Oak and a subsequent Synod in 404, John's opponents Severian, Acacius and Antiochus sought to place priests opposed to John into positions of influence. When Flavian I died shortly after the exile of John[1] they pushed through a rapid election & consecration of Porphyrus while many residents were at the Olympic games customarily held in July or August.[1] The populace was offended that Constantius, Flavian's adjunct and a supporter of John's, was not installed.[1]
