Buongiorno Principessa!

[pcosta]

La targhetta dice "Ritratto della principessa Borghese"
L'autore è Giovanni Piancastelli, che per molti anni fu il curatore della Galleria Borghese (forse il primo museo "moderno" della storia) alla fine dell'800.
La fisso in quegli occhi chiari per nulla italici e mi chiedo (e vi chiedo): ma chi è e da dove discende questa principessa così aristocratica e così poco "borghese"?

Si è poi scoperto qualcosa di questa algida e adolescenziale bionda?
E' giovane, ma il suo volto lascia già immaginare come sarà da vecchia...ci sono tipi di volti così...

Lady Gwendoline Talbot (1835) troppo presto...
Therese de La Rochefoucauld, pure
Heverle Princesse & Duchesse Marie d'Arenberg, anche

con Marie Hunyady de Kethely, figlia del Conte Joseph Hunyady de Kethely e della Principessa Henriette von und zu Liechtenstein oppure Helene Apponyi de Nagy-Appony, figlia del Conte Rudolf Apponyi de Nagy-Appony and Graefin Anna von Benckendorff cominciamo ad avvicinarci...

Margherita Brugmann, da Bruxelles?

Marie Alys de Riquet, Comtesse de Caraman-Chimay, figlia di Eugéne de Riquet, Principe di Caraman-Chimay e Louise de Graffenried de Villars

Meraviglioso! Su che sito hai reperito la genealogia?
Immagino che sia impossibile, vero, cercare di trovare un ritratto delle ragazze che hai nominato per vedere se c'è una qualche rassomiglianza con la donna raffigurata nell'acquerello?
Comunque, anche questo ritratto è introvabile, almeno per me, su Google, mi sa che devo tornare ai cari vecchi libri in biblioteca...
