Passage: Ukrainian customs are heavily influenced by Orthodox Christianity, the dominant religion in the country. Gender roles also tend to be more traditional, and grandparents play a greater role in bringing up children, than in the West. The culture of Ukraine has also been influenced by its eastern and western neighbours, reflected in its architecture, music and art.The Communist era had quite a strong effect on the art and writing of Ukraine. In 1932, Stalin made socialist realism state policy in the Soviet Union when he promulgated the decree "On the Reconstruction of Literary and Art Organisations". This greatly stifled creativity. During the 1980s glasnost (openness) was introduced and Soviet artists and writers again became free to express themselves as they wanted.The tradition of the Easter egg, known as pysanky, has long roots in Ukraine. These eggs were drawn on with wax to create a pattern; then, the dye was applied to give the eggs their pleasant colours, the dye did not affect the previously wax-coated parts of the egg. After the entire egg was dyed, the wax was removed leaving only the colourful pattern. This tradition is thousands of years old, and precedes the arrival of Christianity to Ukraine. In the city of Kolomyia near the foothills of the Carpathian Mountains in 2000 was built the museum of Pysanka which won a nomination as the monument of modern Ukraine in 2007, part of the Seven Wonders of Ukraine action.
