Peter Pannke and Siegfried Zielinski undertake mediaarchaeological excursions into the "deep time” of technical listening and seeing. These excursions take them to places and into historical constellations in which there were still multiple options for the shaping and the development of media. The musician and composer Pannke presents his sound piece “Iternarium Kircherianum” which explores the acoustical world of the Jesuite Athanasius Kircher: a universe full of surprises and extravagant machine fantasies. Zielinski presents excerpts of his an-archaeologlcal research into the forgotten and repressed zones of South and East Europe which have recently been published In a book for publishers rowohlts enzyklopädie.
