Index of Medieval Art (Saint Proculus of Terni, the bishop, but actually Saint Proculus of Pozzuoli, see below)
Chiesa di San Procolo (Bologna), inscription
– 4098 Ambrogio Lorenzetti, Altarpiece of San Procolo in Florence, not either Saint Proculus of Bologna, but rather Saint Proculus of Pozzuoli, 16 November. Also misidentified at the Index of Medieval Art (above).
– 4099 Pacino di Bonaguida, Journey of Saint Proculus, also likely Saint Proculus of Pozzuoli
– 4100 Lorenzo Monaco, Annunciation with Saints, also from San Procolo in Florence
– 4101 Cannot find this, but Pacino di Bonaguida’s Saint Proculus Induces the Doe to give Milk to his Thirsty Companions likely from same altarpiece as 4099 and 4101, both for San Procolo in Florence, for Saint Proculus of Pozzuoli.
– 4102 to 4105 Saint Proculus of Verona’s feast day is 9 December.
