Illustration of a medieval oak panel from Historia Eustachio Mariana

The print illustrates a carved wooden panel divided by arches, showing various religious figures and rituals. In the center, Pope Sylvester I is shown during a dedication ceremony, while the right side depicts the legend of Saint Eustace, featuring a stag with a figure of Christ appearing between its antlers. The lower half of the engraving provides a geometric diagram of a church floor labeled as a pavement pattern.

This work belongs to Kircher’s 'Historia Eustachio-Mariana,' where he used early archaeological methods and historical inquiry to document sacred sites. It represents the 17th-century Jesuit tradition of combining natural philosophy, history, and theology to authenticate religious traditions and relics.
