Head of goddess

The two sides of the Gallery are lined with a row of sculptures of various types from different periods arranged according to strictly ornamental criteria. 
Many statues are Roman copies of original Greek masterpieces, now lost. Modern restoration has, in some cases, greatly altered the original iconography. 
Hundreds of small inscriptions, mainly from the Empress Livia's colombarium of slaves and freedmen on the Via Appia, have been inserted in the walls.
