An artistic research work This monograph by and about the artistic duo Payer Gabriel is an antidisciplinary encyclopedia that literally unfolds its etymological meaning - as a circle of learning in which variable forms of knowledge that mutually inform and reference each other, often in playful ways, circulate. The alphabetically arranged collection of terms is the result of the artists' reflection on their own work, as well as on theories of visual and other epistemologies relevant to their work. For example, an essay by Bruno Latour on inscriptions finds its way into the book not only as an original text, but also via reflection in the form of a drawing and in reference texts. Thanks to these contextualizations, the artistic works transcend their status as documents and develop a life of their own. An original conceptual realization that approaches the book as an independent work of art Multifaceted, aesthetically idiosyncratic illustrations and lithographs With texts by Bruno Latour, Byung-Chul Han, and Odo Marquard
