papal apocrisiarius to Constantinople

The apocrisiarius or apocrisiary was the legate from the pope to the patriarch of Constantinople, circa 452–743, equivalent to the modern nunciature. Nomenclature The term apocrisiarius comes from the Greek word apokrisis, "response". The Latin language name for the office would have been responsalis, from the word responsum. The term was also used by other ecclesiastical envoys, either between bishops or between a bishop and a royal court, although this specific office was one of the first and most notable examples. History and functions In part, the role of the apocrisiarius was to represent the interests of the Roman church at the imperial court in Constantinople. Relations between the pope and the Byzantine Empire were also managed at the court of the Exarchate of Ravenna—where the pope had another permanent apocrisiarius—and between the archbishop of Ravenna and the papacy. The later had a special role as responsalis at the papal court during the papacy of Gregory I. According to the Catholic Encyclopedia, "in view of the great importance attaching to the relations between the popes and the imperial court of Constantinople, especially after the fall of the Western Empire (476), and during the great dogmatic controversies in the Greek Church, these papal representatives at Constantinople took on gradually the character of permanent legates and were accounted the most important and responsible among the papal envoys." Most were deacons, as they were the most educated and potentially skilled in diplomatic negotiations. The apocrisiarius held "considerable influence as a conduit for both public and covert communications" between pope and Byzantine emperor. During the Byzantine Papacy, seven apocrisiarii went on to be selected as pope. According to one commentator, "to be sent as apocrisiarius to Constantinople was to graduate for the papacy." When in Constantinople, the apocrisiarius resided in the Placidia Palace, as early as the end of the Acacian schism in 519.
