HM Queen Elizabeth II, HRH The Duke of Edinburgh and -since today- Sanctus Ioannes PP. XXIII . As the Queen came in full ornate, so did the Pope wearing choir dress and a red mozzetta with white fur.
Back then the papal Household still had the so-called nobiltà nera, aristocrats who -dressed in full ornate- received high guests. You can see them in black velvet and with whitle collars, receiving the Queen and Duke. Often it were princes, marquesses and counts from families as Colonna, Massimo, Orsini, Pallavicini, Borghese, Odescalchi, Ludovisi, etc.
Question: who is the lady with the impressive diadem, arriving behind the Queen? One of the ladies from the nobiltà nera or one of the Queen's Ladies-in-Waiting?
