For the character of the sculptures see Greek Art.
The sculptures belong to a primitive period of art.
The building contained one hundred marble pillars, and was also adorned with sculptures and mosaics sent from Ravenna by Pope Adrian I.
Commodus, who was with his father when he died, erected to his memory the Antonine column (now in the Piazza Colonna at Rome), round the shaft of which are sculptures in relief commemorating the miracle of the Thundering Legion and the various victories of Aurelius over the Quadi and the Marcomanni.
There are several good palaces of the early Renaissance, a fine theatre (1857) and a museum containing important palaeo-ethnological collections, ancient and medieval sculptures, and the natural history collection of Spallanzani.
