The Bauhaus master Johannes Itten was one of the prominent protagonists of early Modernism in twentieth-century art. But few people are aware of the close links between his beginnings as an artist and his experience of landscape and nature in the town of Thun and Lake Thun. Sojourns in Thun and its surroundings were crucial to the development of Itten’s concept of art and his path towards abstraction. Using examples of the representations of nature in Itten’s early work, this volume shows in depth how he discovered his own, very personal—and later internationally famous—approach to art and painting style and presents his pictorial transformation of nature as it extended through to the artist’s late works.
