Inscribed on the two letters in front of the sitter: ' Al Rdo monsig Juliano proton... aptico/ dgmo S.... / a Padua/al borgo dogni santj' (' To the most reverend Monsignor Giuliano, Apostolic Notary, most noble [ Lord, who one addresses] at Padua, at the town of Ogni Santi'). The sitter identified in the inscription is Giovanni Giuliano. There are records of his activity in Venice between 1504-18. His features can be compared with a medal at Brescia (Museo, Civico). There were twelve ' Protonotaries Apostolic', consisting of senior prelates who registered papal legislation & directed the process of the canonisation of saints. This work may have been painted in Padua or possibly in Bergamo in about 1530-40.
