Essays presented to the renown Czech archaeologist Slavomil Vencl on the occasion of his anniversary. The contributions reflect Vencl’s efforts to direct the attention of archaeology not only to the apparent phenomena repeatedly recorded by archaeological finds, but also to the archaeologically invisible components of past culture hardly considered at all by archeologists. The volume includes papers written by a selection of well known Czech archeologists, friends and colleagues as well as pupils, many of whom graduated from the Department of Archaeology, Pilsen University.
