Benedict X, Pope.—The bearer of this name was an antipope in the days of Nicholas II, 1056-61.
The most important source for the history of the first nine popes who bore the name of Benedict is the Tecenbins in the Liber Pontificalis, of which the most useful edition is that of Duchesne, Le Liber Pontificalis (Paris, 1886-92), and the latest that of Mommsen, Gesta Pontif. Roman, (to the end of the reign of Constantine only, Berlin, 1898), Jarrk, Regesta Pont. Rom. (2d ed., Leipzig, 1885), gives a summary of the letters of each pope and tells where they may be read at length. Modern accounts of these popes will be found in any large Church History, or history of t e City of Rome. The fullest account in English of most of them is to be read in Mann, Lives of the Popes in the Early Middle Ages (London, 1902, passim),
Horace K. Mann.
