In this week’s episode of Cocktails with a Curator™, set a course for 18th-century Venice as Deputy Director and Peter Jay Sharp Chief Curator Xavier F. Salomon discusses a pair of “vedute” (views) by Francesco Guardi. Displayed on the third floor of Frick Madison alongside works by Tiepolo and Rosalba Carriera, Guardi’s pictures present a lively city with color-coordinated boatmen, laundry hanging from balconies, and liveried attendants greeting dignitaries. This week’s complementarycocktail is the Sgroppino, a Venetian refreshment dating to the 16th century.
