He flourished towards the end of the ninth and the beginning of the tenth century, and from his writings appears to have been a very learned and accomplished cleric.
He wrote several historical works, important sources of information for the history of his time.
He first wrote a continuation of the diocesan chronicle of Naples (Gesta episcoporum Neapolitanorum), begun by another cleric, but which he brings down from 762 to 872.
[1] He also wrote a history of the translation in the fifth century of the remains of St. Severinus, the Apostle of Noricum, from the Castellum Lucullanum in the Bay of Naples to a new monastery within the city.
This work contains the important account of the destruction of Taormina in Sicily by the Saracens under Ibrahim, and of the martyrdom of Bishop Procopius.
