The poetical joys of Byzantine hierarchy
Steven Runciman's The Great Church in Captivity, is, as its subtitle explains, "A study of the patriarchate of Constantinople from the eve of the Turkish conquest to the Greek War of Independence". But it is actually more than that, because its first seven chapters, roughly 40 percent of the book, are a detailed explication of the Orthodox Church, its theology, structure, movements, and relations with the West.
Yeah, kind of a specialist read, and not the best introduction to Eastern Orthodoxy if you aren't familiar with it. Still, I have a weakness for Byzantine official titles, and while detailing Byzantine administration Sir Steven manages a magnificent hierarchical aria:
...five great offices remained throughout the Byzantine period. They were headed by the Grand Economus, who was in charge of all properties and sources of revenue and who administered the Patriarchate during an interregnum; by the Grand Sacellarius, who, in spite of his title, had nothing to do with the Purse but was in charge of all the Patriarchal monasteries, assisted by his own court and a deputy knows as the Archon of the Monasteries; by the Grand Skevophylax, in charge of all liturgical matters, as well as of the holy treasures and relics belonging to the Patriarchate; by the Grand Chartophylax, originally the keeper of the library but, after the disappearance of the Syncellus and the Archdeacon [vanished offices discussed earlier], the Patriarch's Secretary of State and director of personnel; and finally by the Prefect of the Sacellion, keeper of the Patriarchal prison and in charge of the punishment of ecclesiastical offenders. These five officials were members of the Holy Synod and ranked above all metropolitans [that is, bishops of large metropolitan sees].
If you survived that, you may well enjoy the book. But even I limit myself to small doses, lest I faint from the smell of frankincense.
