The OHO Group, active from 1966 to 1971, were among the most interesting and important representatives of the avant-garde art of the 1960s in central and eastern Europe. In the few years of the group’s existence, its members and associates developed very different artistic strategies and approaches, from the co-called Reism (a concept of a non-anthropocentric world of “things”) to particular forms of Arte Povera, Process Art, Performance and Body Art, Land Art and Concept Art. In the last period of their work, the OHO members created an original combination of Concept Art, ecological concerns and esoteric theories, using such means as telepathy to achieve a balance between the group members themselves and harmony between them, nature and the whole universe. It is especially important that they did not merely accept the already existing art forms but developed original strategies or changed the existing models to fit their philosophy and their circumstances. The group’s Land Art projects are an especially clear example of such an attitude. A comparison with the American Earthworks clearly shows how the OHO projects are determined both by the ecological attitude of the group and specifics of the landscape. The interventions are usually small-scale, non-aggressive, temporary, and not involving heavy machines or complicated technology. Milenko Matanović’s project The Wheat and the String consists simply of a rope strung over a field and slightly bending the wheat. Nevertheless, this minimal intervention creates an emotionally intense picture with rich connotations. Another example is that of David Nez’s mirror installations in landscape, which were contemporary with Smithson’s Mirror Displacements.
