Access is now to be had to some curious vaults below the convent, which were formerly closed by the monks. Supporting these vaults are some remains of massive tufa walls--one piece in particular being about 36 feet long and 8 feet high--consisting of single blocks of stone, of which the other fragments seem to be continuations. These appear to have been built originally as substructions, and run parallel with the Via Marforio, and could not have been part of the city wall, for that is within the city of the two hills. Nibby records that tufa walls remain under the stairs leading up to the Ara Cœli Church. We think them to be part of the foundations of the celebrated Temple of Jupiter Capitolinus. We may mention that among the rubbish contained in the vaults of the convent are two slender columns of Pentelic marble. May not these have belonged to the temple? [Illustration: TEMPLE OF JUPITER CAPITOLINUS.] The strongest evidence of the position of the Temple of Jupiter "supremely good and great" is pictorial. We have it represented on the relief in the Palazzo dei Conservatori which formed part of the Arch of Marcus Aurelius. That emperor is there, after a victory, offering sacrifice upon the Capitoline Hill; and in the background is a representation of the Temple of Jupiter Capitolinus: it has three doors, and the figures of Minerva, Jupiter, and Juno. This is to the spectator's left, and faces south, as we are told the temple faced. This relief is further corroborated by another in the Louvre, in the background of which is likewise a representation of a temple of the Corinthian order, facing the same way and to the left of the spectator, and having over the door the words IOVI CAPITOLINUS. Upon a relief in the Capitol Museum, another building appears upon a lower level, ornamented with pilasters, having Doric capitals. This building corresponds with the front of the Tabularium towards the Capitol. To the right of the Palazzo dei Conservatori (New Museum) a road, through a gate, leads to the German Embassy. In the garden Bunsen found the remains of the Temple of Jupiter Feretrius, which have lately been covered in; but a fine piece of the wall of the Temple of Juno may yet be seen. _By applying at the Embassy, permission will be given to enter the garden._ TEMPLE OF JUPITER FERETRIUS (The Trophy-Bearer). The first temple built in Rome by Romulus, to receive the spoils captured from Acron, King of Cænina. "After the procession and sacrifice, Romulus built a small temple, on the top of the Capitoline Hill, to Jupiter, whom the Romans call Feretrius. For the ancient traces of it still remain, of which the longest sides are less than fifteen feet" (Dionysius, ii. 34. See Livy, i. 10). It was enlarged A.U.C. 121 (Livy, i. 33); and was repaired by Augustus on the advice of Atticus (Nepos. See Livy, iv. 20).
