Casati was known for her eccentricities that delighted European society for nearly three decades. The beautiful and extravagant hostess to the Ballets Russes was something of a legend among her contemporaries. She astonished society by parading with a pair of leashed cheetahs and wearing live snakes as jewellery.
She captivated artists and literary figures such as Robert de Montesquiou, Romain de Tirtoff (Erté), Jean Cocteau, and Cecil Beaton. She had a long term affair with the author Gabriele d’Annunzio, who is said to have based on her the character of Isabella Inghirami in Forse che si forse che no (Maybe yes, maybe no) (1910). The character of La Casinelle, who appeared in two novels by Michel Georges-Michel, Dans la fete de Venise (1922) and Nouvelle Riviera (1924), was also inspired by her.
In 1910, Casati took up residence at the Palazzo Venier dei Leoni, on Grand Canal in Venice, owning it until circa 1924, in 1949, Peggy Guggenheim purchased the Palazzo from the heirs of Viscountess Castlerosse and made it her home for the following thirty years, it is the Peggy Guggenheim Collection, a modern art museum on the Grand Canal in the Dorsoduro sestiere of Venice, Italy.
Party Queen
Casati’s soirées there would become legendary. Casati collected a menagerie of exotic animals, and patronized fashion designers such as Fortuny and Poiret. From 1919 to 1920 she lived at Villa San Michele in Capri, the tenant of the unwilling Axel Munthe. Her time on the Italian island, tolerant home to a wide collection of artists, gay men, and lesbians in exile, was described by British author Compton Mackenzie in his diaries.
Numerous portraits were painted and sculpted by artists as various as Giovanni Boldini, Paolo Troubetzkoy, Adolph de Meyer, Romaine Brooks (with whom she had an affair), Kees van Dongen, and Man Ray; many of them she paid for, as a wish to “commission her own immortality”.
She was muse to Italian Futurists such as F. T. Marinetti (who regarded her as a Futurist) Fortunato Depero, Giacomo Balla (who created the portrait-sculpture Marchesa Casati with Moving Eyes), and Umberto Boccioni. Augustus John‘s portrait of her is one of the most popular paintings at the Art Gallery of Ontario; Jack Kerouac wrote poems about it and Robert Fulford was impressed by it as a schoolboy.
