PRIVATA (DOMUS) HADRIANI
the house of Hadrian in Region XII
in which he lived before his adoption, and where Antoninus Pius lived
after his adoption by Hadrian (Hist. Aug. Marc. 5). Its place in the
list of the Notitia would point to a site near S. Saba, probably towards
the south-west (HJ 187; Merlin 326, 343).
