[1] There is no basis for the Genovese provenance of the panels beyond an unattributed statement in the NGA curatorial file from the Kress Foundation. No donor portraits or triptych positively identifiable with 1961.9.10 and 1961.9.11 are listed in Carlo Giuseppe Ratte, _Instruzione de quanto puo' vedersi di più bello in Genova in pittura, scultura ed Architettura_, 3 vols. (Genoa, 1780), or Federigo Alizeri, _Guida artistica per la Città de Genova_, 2 vols. (Genoa, 1846).
[2] The Count lived in Rome until 1931.
