The villa has an even larger second peristyle on the southern side, partially excavated, approximately 140m long, with arcades supported by spiral columns which collapsed during the 1980 Irpinia earthquake: the ceilings are painted with scenes depicting Melpomene, the Apotheosis of Athena etc.. In this peristyle was a sundial found during the excavation in a deposit as the villa at the time of the eruption was under renovation; the sundial was subsequently placed in its original position.
