As an answer to the curator’s request for instructions for him to produce a work, a common stone, picked in the banks of the Main river, in Frankfurt, was sent to Lisbon, by post, along with the request for him to create a narrative, a fact, or a situation that would justify its inclusion in the collection of the Department of Geology of the archive of destruction. Instead of the selection of an object that carries already within itself a symbolism and memory that entitles it to be representative and testimony of a specific event, and therefore to be protected in an archive, this started with an arbitrary choice of an anodyne object which bore no traceable evidence of history or relevance, being these artificially created after the random selection of the object.
