FOLIO CLVII recto

Constantine (Constantinus), son of the emperor Constans , received the Roman sovereignty after Constans and Mezezius (Mesentio); and he reigned seventeen years. This Constantine (who previously had been taken into the sovereignty by his father Constans as an associate) was so crushed by fear after the assassination of his father (as mentioned above) that he managed all matters so timidly that he might have lost the sovereignty if any force had been raised against him. Later he was a brave and very virtuous Christian man, and after receiving the sovereignty, he shared it in common with his brothers Heraclius and Tiberius whom he took into it with him. However, some write that he deprived his brothers of their noses, although they did not aspire to the sovereignty. Afterwards he restored the churches which had been destroyed by the heretics in the time of Heraclius; and he also built other churches. Being a warlike man and experienced in the use of arms, he defeated the Saracens, enemies of the Roman Empire, in war; and in the tenth year of his reign he so overcame the Saracens by a speedy victory that they chose to pay taxes and tribute to the empire. Upon these terms he made peace with them, and returned to Constantinople. To bring about unity between the Roman church and the other churches he called the Sixth Council at Constantinople at the suggestion of Agatho, the pope. And now being full of good works, he died at Constantinople, leaving his son Justinian as his successor to the sovereignty.[Constantine IV, Pogonatus (the “bearded”), son of Constans II, was emperor from 668 to 685. After his accession he crushed an Armenian usurper in Sicily. The Arabs besieged Constantinople for six years, but were finally obliged to make peace, and agreed to pay tribute for 30 years. The attacks of the Slavs and Avars upon Thessalonica were repulsed. But Constantine was unable to keep out the Bulgars who crossed the Danube and established the Bulgarian kingdom in his territory. The tribute paid by the Arabs was used to purchase the good will of the new settlers. Constantine summoned the Sixth Ecumenical Council at Constantinople, which sat from November 7, 680 to September 16, 681.]

The Sixth Ecumenical Council was called by the emperor Constantine at Constantinople. Two legates of Pope Agatho were present, namely, John, the bishop of Portuensis, and John, a deacon of the Roman Church. And so, at the command of the emperor, came two hundred eighty-nine bishops. The case of the Monothelite heretics was earnestly considered. Contrary to the true Christian faith, these heretics held that there was but a single will in Christ. Two bishops were responsible for these things— George (Georgius), of Constantinople, and Macarius (Marcharius), bishop of Antioch. And although George, after the presentation of sensible views was easily dissuaded from his error, Macarius, was tenacious in strongly resistant to changing his mind; for this reason he was not only deprived of his episcopate, but, together with the deceased heretics Sergius, Pyrrhus, Paul, and Peter, their followers in the same error, was given over to the Satan. Finally, together with a number of relatives, they were sent to Rome. Theophanus, the abbot, was installed as bishop in the place of Macarius. Now, in thanksgiving to the Lord God for the unification of the two churches, the aforesaid bishop of Porto (Portuensis) held the office of the holy mass in Latin on the eighth day of Easter in the Basilica of Saint Sophia in the presence of the emperor, the patriarch, and the people of Constantinople; and all present acknowledged that such was the correct and holy manner of holding the mass. In this Council it was concluded that according to the correct interpretation of holy Christian teaching there were two natures and wills in Christ, and not a single one as claimed by the Monothelite heretics.[The Sixth Ecumenical council (680-1) was convened at Constantinople by the emperor Constantine IV to terminate the Monothelite controversy. All the Patriarchates were represented, Constantinople and Antioch by their bishops in person, the others by legates. The council approved the first five ecumenical councils. Monothelitism was condemned; Christ was declared to have had “two natural wills and two natural operations, without division, conversion, separation or confusion.” Prominent Monothelites, living or dead, were anathematized, in particular Sergius and his successors in the see of Constantinople, the former pope Honorius, and Macarius, the patriarch of Antioch. An imperial decree confirmed the council, and commanded the acceptance of its doctrines under pain of severe punishment. The Monothelites fled to Syria, where they gradually formed the sect of the Maronites.]

A comet appeared in these times for three months continuously; then came a heavy rain, and thunderbolts not experienced before. The elements performed as if they had conspired to destroy the city of Rome and the land of Italy. Much cattle died in consequence, and the people sustained great damage. Many men were struck by lightning and died. Crops wilted and dried up in the fields, so that melons, beans, lentils, and the like were a great rarity to the people; and the grain was beaten out by the wind, and matured as mere shrubbery.

Afterwards eclipses of the sun and moon were followed by a severe pestilence that devastated the city of Pavia, so that the people fled to the mountain heights, and the city grew up with shrubbery and weeds.
