In the negative space of human architectures, agents operate that consume matter and precipitate its destruction. The constructions of termites and other plagues, in the literal context of the shadows in which they thrive, behind the woodcarvings and inside the built heritage, are captured in video. The recordings took place in a contemporary ruin of the recent past, the Palace of São João Novo, which housed the Museum of Ethnography and History, up to 1974, and was then taken by architect Fernando Lanhas until it faded in time.
