In an echo of ruangrupa’s January 2019 proposal for documenta fifteen, in which the collective clearly outlines its goals as being that of building a global network of institutions and initiatives capable of outlasting this documenta edition, the documenta issue brought to you by Simulacrum hopes to position itself as one of the many available tools in understanding lumbung. Pointing to lumbung as one mechanism among a richness of practices for collective sustainable thinking in the field of arts & culture, we approach documenta fifteen as both a situated event within documenta history, and as a collaborative experiment in the sharing of knowledge and resources.
