St Justina of Padua with a Donor

St Justina of Padua with a Donor is a oil on panel painting by Moretto da Brescia, executed "c." 1530, now in the Kunsthistorisches Museum in Vienna, to which it was transferred in the late 19th century soon after the Museum's opening. It shows Justina of Padua.
Its original location is unknown and no documents survive stating its provenance or commissioner. The first surviving reference to the work is in a 1662 document relating to its move from the Hofburg to Ambras Castle (it was then in the Holy Roman Empire's collections). That document referred to it as a work by Titian and in inventories immediately before the move it was ascribed to Raphael. A 1733 inventory re-attributed it yet again, this time to Pordenone. In 1845 Ransonnet restored its correct attribution to Moretto.
