NICEPHORUS, Calistus, a Greek historian, who flourished in the 14th century under the emperor Andronicus Paleologus the elder, wrote an ecclesiastical history in 23 books; 18 of which are still extant, containing the transactions of the church from the birth of Christ to the death of the emperor Phocas in 610.—We have nothing else but the arguments of the other five books, from the commencement of the reign of the emperor Heraclius, to the end of that of Leo the Philosopher, who died in the year 911. Nicephorus dedicated his history to Andronicus Paleologus the elder. It was translated into Latin by John Langius; and has gone through several editions, the best of which is that of Paris, in 1650.
