On October 29, 2010, Ambassador Beyrle celebrated the connections between American and Russian literature and culture by hosting an Enchanted Ball at Spaso House. The ball recalled the Spring Ball of 1935 held by Ambassador William Bullitt, when the house was decorated with live birds, a birch forest, and a real bear. One of the guests at the 1935 ball was writer Mikhail Bulgakov, who used elements of that ball as an inspiration for Woland's Ball in his novel Master and Margarita.
