From the reference to the bullae, a commercial exchange system used more than 8,000 years ago in Mesopotamian cities and based on a descriptive graphic code that guaranteed the correspondence between price and product, this piece illustrates in a heterodox way, a precedent of the monetary system that is based on trust and the authentication of the correspondence of values. A showcase with a collection of object fragments, archaeological documents and manipulated images proposes the documentary tracing of a Past economic system that causes mistrust in the naturalization of the current economic system as the only way of commercial understanding. A mosaic is offered that, in an unusual game of associations, escapes from easy reading in breaking the narrative discourse on the idea of progress linked to the historical evolution and to the economic vision of the world. Hence, the proposal conforms as a kind of visual essay that aims to reconfigure the sensible order of things and articulates an alternative knowledge, apart from the monolithic and compact discourse imposed by the spheres of power.
