The buildings on the outside of the vaults of the oldest rooms reused sculptures presumably belonging to the decoration of the horti as building material. Here were found the beautiful statue of Marsyas in pavonazzetto marble, the statue of the muse Erato, the statue of a dog from Egypt, a splendid statue of Demeter, etc. In addition Lanciani pointed out " several torsos of fauns and Venus, a flower vase worked in the form of a puteal and decorated with ivy and flowers; a broken altar (...), the lower part of a group of a hero and a draped woman; seven herms of Indian Bacchus, philosophers, athletes ... ". Together with the sculptures there were also numerous mosaics, including those in opus vermiculatum mounted on tiles, to be used as central emblematic of precious floors.
