The chronology of Andreas Agnellus in LPR is confused: He lists only one bishop of Ravenna with the name John in the 5th century. He omits the years 430–433 as a separate period of office, conflating John Angeloptes (who is "John I") with John II. He mistakenly assigns events from Angeloptes' time, in the earlier part of the century, to the episcopate of John II (477–494) – or, as Agnellus designates him by this error – "John Angeloptes", thus "John I".[13] This confusion is explained by the 19th century historian, Thomas Hodgkin:
St. John II ruled the See from 477 to 494. Here at last we get two certain dates from the inscription on his tomb, and the recovery of this name and these dates enables us to correct an omission of Agnellus and to understand the cause of the wild errors which he has committed in his chronology. For it is now clear that in his life of John the Angel-seer he has run two bishops into one, and has calmly blended transactions reaching over a period of some sixty or seventy years, the death of Honorius, the invasion of Attila, the war between Odovacar and Theodoric, in his life of a bishop who according to his own account ruled his See for 16 years, 10 months, and 18 days.
It was this John II who negotiated the peace, the short-lived peace between Odovacar and Theodoric which terminated the long siege of Ravenna (493).
