been neglected in historiography is not that they were any less able than their ancient or modern Greek colleagues in matters of trade. It rather originated with the way history was written in Byzantium, which was often under the patronage of their competitors, the court, and land aristocracy. The fact that they were eventually surpassed by their Italian rivals is attributable to the privileges sought and acquired by the Crusader States within the Levant and the dominant maritime violence of the Italians. Clergy Unlike in Western Europe where priests were clearly demarcated from the laymen, the clergy of the Eastern Roman Empire remained in close contact with the rest of society. Readers and subdeacons were drawn from the laity and expected to be at least twenty years of age while priests and bishops had to be at least 30. Unlike the Latin church, the Byzantine church allowed married priests and deacons, as long as they were married before ordination. Bishops, however, were required to be unmarried. While the religious hierarchy mirrored the Empire's administrative divisions, the clergy were more ubiquitous than the emperor's servants. The issue of caesaropapism, while usually associated with the Byzantine Empire, is now understood to be an oversimplification of actual conditions in the Empire. By the fifth century, the Patriarch of Constantinople was recognized as first among equals of the four eastern Patriarchs and as of equal status with the Pope in Rome. The ecclesiastical provinces were called eparchies and were headed by archbishops or metropolitans who supervised their subordinate bishops or episkopoi. For most people, however, it was their parish priest or papas (from the Greek word for "father") that was the most recognizable face of the clergy. Culture Language The Eastern Roman Empire was in language and civilization a Greek society. Linguistically, Byzantine or medieval Greek is situated between the Hellenistic (Koine) and modern phases of the language. Since as early as the Hellenistic era, Greek had been the lingua franca of the educated elites of the Eastern Mediterranean, spoken natively in the southern Balkans, the Greek islands, Asia Minor, and the ancient and Hellenistic Greek colonies of Southern Italy, the Black Sea, Western Asia and North Africa. At the beginning of the Byzantine millennium, the koine (Greek: κοινή) remained the basis for spoken Greek and Christian writings, while Attic Greek was the language of the philosophers and orators.
