[6] Using methods like X-ray, petrography, thermogravimetric analysis, macroscopic observations, it is found that typical pottery sherds and tile fragments constituent of abundant quartz, feldspar, minor amount of mica, lithic, and grog.

This excavation resulted in two highly significant archaeological discoveries: a stone stele "evidence of a permanent religious cult with monumental dedications, at least as early as the Late Archaic Period, from about 525 to 480 B.C.

The parts of the inscription that could be transcribed attest to the goddess Uni being the primary recipient of worship and sacrifice at the Poggio Colla sacred site, but also mention her consort, the god Tinia.

At one time it would have been displayed as an imposing and monumental symbol of authority.”[10] The second significant discovery was the birth-stamp; a small image of a woman giving birth that was found on a shard of bucchero pottery.

The image shows the head and shoulders of a baby emerging from the mother, who is represented with her face in profile, with one arm raised, thought to be holding on to possibly a tree for support.

When its context—a redeposited occupation stratum of a settlement dated to the end of the Orientalizing period—is assessed in conjunction with its iconography, it becomes possible to view the stamp’s imagery as alluding to concepts of fertility and reproduction tied to the power of nature and regeneration, all of which would have been appropriate in an Etruscan banqueting context attended by elite men and women.
