Along with the Venice Biennale, documenta in Kassel is considered the most important, cyclically recurring exhibition of modern and contemporary art in the world. Many refer to it as THE world art exhibition. Thanks to the initiative of the artist and designer Arnold Bode, it first took place in 1955 and was initially held every 4 years, since 1972 it has been held every 5 years. Since documenta 5, an artistic director has been appointed for each documenta exhibition.
