The right-hand side of the ascent was bordered with honorary monuments and inscriptions to Trajan, Hadrian, Titus, Septimius Severus, Caracalla, and Constantine; but the most interesting, perhaps, was the monument with Greek inscription of Gordianus, erected to him by the citizens of Tarsus, St. Paul's city, and interesting as showing that the close friendship between Rome and Tarsus continued to this late period. Four columns of Porta Santa marble stood on a podium, 7 feet by 4 feet, and supported a canopy, under which was the emperor's statue. On the cornice was the inscription, ΤΑΡϹΕωΝ , filled in with bronze. THE VICUS SANDALIARIUS. This was the street mentioned by Dionysius as leading into the Carinæ. In the "Curiosum" and "Notitia" is mentioned the Apollinem Sandaliarium. This was a statue of Apollo, which gave name to a street of the fourth region. Suetonius ("Aug." lvii.) says: "With which donations Augustus purchased some costly images of the gods, which he erected in several of the streets of the city, as that of Apollo Sandaliarius." It is mentioned by Aulus Gellius (xviii. 4): "In Sandaliario forte apud librarios fuimus." Also by Galen ("De Libris suis," iv. 361). The marble plan of Rome shows this street by the letters DLARIVS. This was the street, recently excavated, between the Temple of the Penates and the Basilica Constantine, and which led into the Suburra. At the entrance from the Via Sacra there still exists a brick pedestal on which the statue may have stood. For engraving of this, see Gruter, cvi. 7, and Dcxxi. 3. In this street the remains of the Temple of Venus and Rome can be distinctly seen. A short distance up it is tunnelled over to allow the Basilica of Constantine to square; but the tunnel is closed about half way through. From the level of the street the western tribunal of the Basilica has been built up. The tunnel, called Arco d'Ladroni, and the street itself, have been used as a burial-place by the monks of the church; and there is a ninth century fresco of the dead body of the Saviour over a shrine on the left. _Beyond is the_ BASILICA OF CONSTANTINE, the colossal arches of which have served as models to architects for building all the larger churches in Rome. This splendid ruin usually bears the name of the Temple of Peace, erected by Vespasian in this neighbourhood and partly on this site, and which was destroyed by fire as early as the time of Commodus, A.D. 191. Herodianus, who saw the fire, says: "By the slight earthquake and the thunderbolt which followed it, the whole of the sacred enclosure was consumed." Claudius Galenus, the celebrated physician, says that the whole edifice was consumed, as also most of his writings, which were in his shop in the Via Sacra.
