Marta Berezowska, a ballet pupil of Polish descent, does her practice exercises at home in Lviv during the vacation. The interior of her flat on Dudayev Street has echoes from the Habsburg era. Lermontov Street, named after the patriotic Russian writer, was renamed Dudayev Street, after the Chechen separatist killed by the Russian military in 1996, in a telling indication of the sympathies of the city council. Ukrainian nationalism, and anti-Russian sentiment, is perhaps stronger in Lviv than anywhere else in Ukraine. But much of Lviv\'s population is ethnically Russian, and nowhere is the Russian identity stronger than at the ballet, where there is a harmonious mixing of nationalities.
