Giovanni Visconti, Bishop of Sabina

The modern scholars have concluded that no such cardinal existed in 13th century because the suburbicarian see of Sabina was occupied by Bertrand de Saint-Martin
from 1273 until at least 1277. The document of Pope John XXI
concerning the postulation of bishop Giovanni of Potenza to the see of Monreale actually refers to cardinal Bertrand and even explicitly calls him by name.
