Mensurius bishop of Carthage, of whose personal history but little is known, figured very prominently during the Diocletian persecutions. He seems to have been identified with the liberal or Arian party, and to have entertained heretical opinions, to which he gave publicity in books published under the title of "Sacred Scriptures." He opposed the enthusiastic veneration of the confessors who were kept in prison At the synod held at Ceuta, AD. 305, he was arraigned for these acts, but, as most of the African bishops were accused of the same crime, the matter was passed over. Later a new charge was brought against Mensurius, and he had to defend himself at Rome in 311. It seems that he there cleared himself, but on his return home he died. Under his successor in the bishopric the Donatist quarrels opened. SEE DONATISTS.
