a name which appears to have been given at a late
date to the Quirinal hill, and occurs only in an emended passage in
Lydus (de mens. iv. 155, ed. Bekk. 118:τιβο[ύρτιον]
; cf. Wissowa,
Ges. Abh. 233; HJ 229). Like PRAENESTIUS COLLIS
(q.v.) the name is
derived from that of a gate (Porta Tiburtina) in the Aurelian wall, and
was probably the invention of some antiquarian.
