On the other hand, Narses after the victory took Rome, and coming to an engagement with Teias near Nocera, slew him and routed his army.

By this victory, the power of the Goths in Italy was quite annihilated, after having existed for seventy years, from the coming of Theodoric to the death of Teias.
No sooner was Italy delivered from the Goths than Justinian died, and was succeeded by Justin, his son, who, at the instigation of Sophia, his wife, recalled Narses, and sent Longinus in his stead.

Like those who preceded him, he made his abode at Ravenna, and besides this, gave a new form to the government of Italy; for he did not appoint governors of provinces, as the Goths had done, but in every city and town of importance placed a ruler whom he called a duke.

Neither in this arrangement did he respect Rome more than the other cities; for having set aside the consuls and senate, names which up to this time had been preserved, he placed her under a duke, who was sent every year from Ravenna, and called her the duchy of Rome; while to him who remained in Ravenna, and governed the whole of Italy for the emperor, was given the name of Exarch.

This division of the country greatly facilitated the ruin of Italy, and gave the Lombards an early occasion of occupying it.
Narses was greatly enraged with the emperor, for having recalled him from the government of the province, which he had won with his own valor and blood; while Sophia, not content with the injury done by withdrawing him, treated him in the most offensive manner, saying she wished him to come back that he might spin with the other eunuchs.
