The B&B where we stayed in Venice was called Bianca Cappello House.
Turns out that Bianca Cappello is not the name of the nice lady who owns the place, but that of a Venetian noblewoman born in 1548, who according to wikipedia, was the mistress and afterward the second wife of Francesco I de Medici, the Grand Duke of Tuscany.
She was very beautiful and several portraits were made. A couple of centuries later, English writer Horace Walpole would fall in love with one of these portraits and, in a letter to a friend about one of these paintings, for the first time he used the word serendipity.
Horace was loosely related to Spencer Walpole, after whom is named the park at the end of my street in London.
