write about the Jews the same as Chrysostom: Epiphanius, Diodorus of Tarsus, Theodore of Mopsuestia, Theodoret of Cyprus, Cosmas Indicopleustes, Athanasius the Sinaite among the Greeks; Hilarius of Poitiers, Prudentius, Paulus Orosius, Sulpicius Severus, Gennadius, Venantius Fortunatus, Isidore of Seville, among the Latins." From the 4th to 7th centuries, while the bishops opposed Judaism in writing, the Empire enacted a variety of civil laws against Jews, such as forbidding them from holding public office, and an oppressive curial tax. Laws were enacted to harass their free observance of religion; Justinian went so far as to enact a law against Jewish daily prayers. Both Christians and Jews engaged in recorded mob violence in the waning days of the Empire. Through this period Jewish revolts continued. During the Byzantine–Sasanian War of 602–628 many Jews sided against the Byzantine Empire in the Jewish revolt against Heraclius, which successfully assisted the invading Persian Sassanids in conquering all of Roman Egypt and Syria. In reaction to this further anti-Jewish measures were enacted throughout the Byzantine realm and as far away as Merovingian France. Soon thereafter, 634, the Muslim conquests began, during which many Jews initially rose up again against their Byzantine rulers. The pattern wherein Jews were relatively free under pagan rulers until the Christian conversion of the leadership, as seen with Constantine, would be repeated in the lands beyond the now collapsed Roman Empire. Sigismund of Burgundy enacted laws against Jews after coming to the throne after his conversion in 514; likewise after the conversion of Reccared, king of the Visigoths in 589, which would have lasting effect when codified by Reccesuinth in the Visigothic Code of Law. This code inspired Jews to aid Tariq ibn-Ziyad (a Muslim) in his overthrow of Roderick, and under the Moors (also Muslims), Jews regained their usurped religious freedoms. After the 8th century Beginning with the 8th century, legislation against heresies grew more severe. The Church, once confining itself to only the powers of canon law, increasingly appealed to secular powers. Heretics such as the Vaudois, Albigenses, Beghards, Apostolic Brothers, and Luciferians were thus "treated with cruelty" which culminated in the 13th century establishment of the Inquisition by Pope Innocent III. Jews were not ignored by such legislation, either, as they allegedly instigated Christians to judaizations, either directly or unconsciously, by their existence. They sent forth metaphysicians such as Amaury de Béne and David de Dinan; the Pasagians
