Easter also stands for the begin of spring. The German literature has a lot of Easter poems which are referring to the seasonal issue. The most popular German Easter riddle is "Der Osterspaziergang" (the Easter walk ostern) from Johann Wolfgang von Goethe. It starts with the line "Vom Eise befreit sind Strom und Bäche" ("freed from the ice are rivers and creeks").
