BALNEUM CAESARIS
inscribed on a fragment (49) of the Marble Plan.
These may possibly be the baths of the palace (balneum Palatii) in which
Didius Julianus was murdered by Sept. Severus (Aur. Vict. Ep. 19;
cf. also Hist. Aug. Alex. Sev. 23:
nec quicquam in Palatio curare
(eunuchos) fecit nisi balneas feminarum).
