the latter. In 1064, Peter's second son Geoffrey refers to his father as magni comitis Petroni in an act donating one ship to the monastery of the Santissima Trinità in Venosa for fishing on the Mar Piccolo, the bay of Taranto. Peter's youngest son, Peter II, likewise confirmed this donation pro remedio anime (ejus) ("for the health of [their father's] soul"). Peter I had not taken Trani by the time of his death. He is sometimes confused with his son Peter. The "count Petrone" who defeated Argyrus in 1053 has an entry in the Prosopography of the Byzantine World'' and is identified there with the son of Amicus, that is, Peter I, though other source believe the Petronius of 1053 was Peter II. "Petronius" is an augmentative of Peter, and indicates greatness (probably of stature). Peter I's relationship to his son Geoffrey is mentioned in Lupus Protospatharius. Peter's eldest son, Amicus, is barely known. External links I Conti di Trani Prosopography of the Byzantine World Italo-Normans Norman mercenaries Norman warriors 11th-century Normans
