A woman looks at traditional Ukrainian Easter eggs “Pysanka”, installed as part of the upcoming celebrations of Easter, in central Kiev, Ukraine, April 29, 2016. A pysanka is a Ukrainian Easter egg, decorated with traditional Ukrainian folk designs using a wax-resist (batik) method. The word pysanka comes from the verb pysaty, “to write”, as the designs are not painted on, but written with beeswax.

These include the Belarusians, Bulgarians, Croats, Czechs, Hungarians, Lithuanians, Poles, Romanians, Serbs, Slovaks, Slovenes and Sorbs. (Photo by Valentyn Ogirenko/Reuters)
