A list of the successors of St. Peter made by Eusebius. He acknowledged that there was great difficulty in procuring information, and his account appears to have been compiled chiefly from reports or traditions. Of his fidelity he has given proof, by leaving vacancies in his conjectural list, when he had no light to guide him. These vacancies were subsequently filled up by Nicephorus, Callistus, and Simon the Metaphrast (see Elliott, Delineation of Romanism, p. 498). (See SUCCESSION).
