On the other side of this street is an entrance to the subterranean caves which have been cut in this part of the hill. These hollows were mainly stone quarries and wells. A puteal, or well-cover, has been placed over one of these in front of the house which we have described. On this side of the street also stand the foundations which have been supposed to have belonged to the priests of the Temple of Jupiter Propugnator on the Palatine, some portions of the fasti of whose college have been found near the Basilica Julia and the Marforio.[23] There is also the foundation of a temple, called by Rosa the Temple of Jupiter Victor, to be seen extending from this street towards the viridarium of the ædes publicæ of Domitian before mentioned, and towards the edge of the hill which looks over the Circus Maximus. These ruins consist of masses of tufa work mixed with later brickwork of the Antonine times. The pedestal with the name of Gnæus Domitius Calvinus which is placed here came, as we have said, from the spot called the Area Palatina before mentioned. The Notitia also places the Temple of Jupiter Victor in the Area Palatina, and for these two reasons the name seems to be wrongly applied to this ruin. We can trace in it the remains of a building raised on a basement with lofty flights of steps, alternating with terraces in front, towards the Circus Maximus, just as we find at Tibur and at Tusculum temples, placed on the side of a hill with high flights of steps ascending to them.[24] [Sidenote: Germalus and Scala Caci.]
