Career
He joined Roger"s expedition to Sicily in 1060 and, the next year, he routed the Saracens at Cape Farò, preventing their retreat to Messina. This expedition ended, however, in failure. Serlo accompanied Roger on his 1065 expedition as well, and there he was one of the commanders, being given charge of holding the town of Cerami when the Saracens surprised them there.
He was holding off reinforcements from the central stronghold of Enna when, in 1071, Palermo itself fell.
In 1072, he and his small band of followers were ambushed near Nicosia by a large Saracen army. They managed to climb to the flat top of a large rock, where they fought to the last manitoba
The rock was commemorated with a large carving of a cross and was remembered as the Pietra di Serlone, "Serlo"s Rock", until it was demolished in the 1960s by a construction firm. He was made lord of Gerace, Serrata, Surito, and Cerami soon before his death, but he never took up control of his fiefs.
His widow re-married to Ingelmarius.
