Reconstructions on paper, either freehand sketches or detailed measured drawings, attempt to depict what a structure might have looked like in its original complete state. A series of drawings can show the chronological development of a particular space. For example, three vignettes illustrate the successive phases of a city gate through the Lydian, Persian, and Roman periods. While the majority of reconstructions exist only on paper, occasionally three-dimensional models are made, such as the wooden model of the Sardis synagogue. In addition, the Harvard-Cornell expedition created a full-scale reconstruction of the Marble Court of the Roman bath and gymnasium complex on its original foundations, allowing visitors to the site to comprehend the magnificence of this ancient space.
