Boniface VII, who attained the papal chair in 974, is sometimes styled an
antipope. He is supposed to have put his predecessor,
Benedict VI, to death. A popular tumult compelled him to flee to
Constantinople; but he carried with him vast treasure, and in 984
he returned and removed by murder,
John XIV[?], who had been elected in his room. He died in 985 or 986.
