Berardo was born into the noble family da Pagliara, whose castle bore their name near the town of Isola del Gran Sasso in the Abruzzo region of Italy.
Important information concerning his life is found in the ancient church records from this area as well as the chronicles of his successor, the Bishop Sassone.
He took on this role for seven years beginning in 1116 and focused his efforts on helping the poor and making peace amongst the warring factions of the local citizenry.
He was buried in what today is known as St. Anne's chapel in the ancient Teramo Cathedral of Santa Maria Aprutiensis (now Sant'Anna dei Pompetti).
An outstanding and varied collection of engravings and prints related to Berardo was chronicled and organized by Raffaele Aurini in 1973.
