The distinction between internal and external spaces, public and private, was not a fundamental characteristic of the environments at the time. Interior rooms often opened outwards, displaying their decorative setup on the façades; exterior courtyards were dressed as internal chambers instead. Various devices were put in place to recreate these micro-architectures, from tapestries used as structural walls, to architectural apparatuses that simulated ephemeral scenes, to sideboards used as display furniture. This hybridisation characterises the habits of the time, in which the concepts of the public and the domestic place were often unpredictable and ephemeral or dependent on specific social constructs.

One of the first temporary and ephemeral exhibition spaces can be found in the tent (skené) erected by Ptolemy II Philadelphus and described by Athenaeus of Naucrati (2nd–3rd century CE) in I Deipnosofisti. Inside the tent, walls were decorated with fabrics and hides, while the architrave supporting the ceiling was covered with tapestries interspersed with painted panels. In this setup, the exhibiting role of the structure met the decorative function, thus defining a temporary and modular micro-architecture.
