their clergy at the order of the legate. The peace of Nuremberg was to extend until the time of the future council, but the Augsburg Recess was to be maintained. These decisions might have become very dangerous to the Protestants, and in order not to force them into an alliance with his foreign opponents, the emperor decided to change some of the resolutions in their favor; but the Roman Catholics did not acknowledge his declaration. As he was not willing to expose himself to an interpellation on their part, he left Regensburg on June 29, without having obtained an agreement or a humiliation of the Protestants, and the Roman party looked upon him with greater mistrust than the Protestants. (T. Kolde.)

REGINO, re-gi'no: Abbot of Priirn; b., according to a sixteenth-century tradition, at Altrip (a village near Ludwigshafen, 36 m. s. of Mainz) in the ninth century; d. at Treves 915. He entered the monastery of Prum, and in May, 892, was chosen abbot, but was forced by jealous opponents to resign in 899. He then went to Treves, where Archbishop Ratbod entrusted to him the restoration and administration of the monastery of St. Martin, which had been destroyed by the Normans. Since, however, he was buried in the monastery of St. Maximinus near Treves, it would seem that he was not in control of St. Martin's at the time of his death. All the known works of Regino were composed at Treves. In 906 he wrote his Libri duo de synodalibus causis et disciplinis ecclesiasticis (best ed. by F. G. A. Wasserschleben, Leipsic, 1840) to further episcopal discipline; he also composed a treatise on the theory of church music, the De harmonica institutione (ed. C. E. H. de Coussemaker, Scriptores de musica medii cevi, Paris, 1863-76, ii. 1-73). His most important work, however, was the Chronica, from the birth of Christ to 906, which was completed by 908 and was the first German attempt at a universal history (best ed. by F. Kurtze, MGH, Script, rer. Germ., Hanover, 1890). The work falls into two books, from 1 to 741 and from 741 to 906, the latter portion being practically restricted to Frankish history, especially of the western Frankish kingdom. This second part is of great value for Lothringian history, and it was continued to 967 at the monastery of St. Maximinus, apparently by Adalbert, subsequently archbishop of Magdeburg. (O. Holder-Egger.)

REGION ARIUS, re"gi-on-a 'ri-us: In the premedieval Roman Church an official, primarily a deacon, placed over one of the ecclesiastical regions, originally seven in number, of the city of Rome. The institution is ascribed by the Liber pontificalis to both Clement I. and Fabian, the latter being the more probable. Each deacon was assisted by a subdeacon and a notary, while the Ordo Romanus also mentions regionary acolytes, and Gregory I. seems to have established " regionary defenders." The seven regionarii of Rome later became the cardinal deacons, whose number was raised to fourteen, and the regionary notaries were developed into the prothonotaries (see Prothonotary Apostolic).
