Byzantine Historians, a series of little read but important lower Greek authors, who wrote between the 4th and 15th centuries chiefly on the history of the Byzantine empire. Among the most noteworthy of them are Zosimus, Procopius, Agathias, Constantine Porphyrogenitus, Cedrenus, Anna Comnena, and Zonaras. Of these, Procopius is the best known, and is the only one who has been translated into English. Anna Comnena, daughter of the emperor Alexis I., who wrote a history of her father's reign, is also well known. A collection of the most important of them was made and published at the expense of Louis XIV. (Corpus Scriptorum Historice By-zantinm, 36 vols., Paris, 1648-1711). The Greek text is accompanied with a Latin translation and notes. The editors of this work were the Jesuits Labbe and Maltrait, Petau and Poussines, the Dominicans Goar and Com-befis, Prof. Fabrotti, Du Cange, Allacci, the librarian of the Vatican, Banduri, librarian at Florence, Boivin, the royal librarian at Paris, and Bouilliaud, a mathematician. Another edition, with additions, was published at Venice (23 vols., 1729-'33). Some, not included in either collection, have been published separately since.

Niebuhr entertained a high opinion of the value of the Byzantine historians in a general history of mankind, and projected a new edition of them, which was commenced in 1828, under the title Corpus Scriptorum Historiae Byzantium, Editio emen-datior et copiosior (Bonn). Of this edition 48 volumes were published. Bekker, the two Dindorfs, Schopen, Meinecke, and Lachmann were the principal editors. The best key to the language of these writers is the "Greek Lexicon of the Roman and Byzantine Periods," by Prof. E. A. Sophocles of Harvard university (Boston, 1870).
