<p>Remains of an extremely long-lived residence have been located beneath S. Pudenziana on the *Viminalis. Though most of the walls date to the 2nd c. A.D., a portion in <i>opus reticulatum</i>, as well as substantial remains of late-Republican or Augustan mosaics, suggest a residence of the early-Augustan era (Petrignani, Krautheimer). One room preserves indications of an earlier pavement of hydraulic cement with inserted fragments of colored marble (Petrignani); Coarelli dates this floor to the 2nd c. B.C., which suggests the residence was continuously inhabited for <i>c</i>. 400 years. Milella neglects these earlier phases, and places all the remains below the church in the 2nd c. A.D.</p>
