Among these was a statue of Isis now in the hall of the dying gladiator in the Capitol, the two Egyptian lions now at the foot of the steps of the Capitol; the famous group of the Nile now in the Braccio Nuovo of the Vatican, and two fragments of an altar with Egyptian reliefs, and the inscription ISIDI SACRUM. Further traces of the same Egyptian worship were found by Canina in the year 1852, of which he has given an account in the Annali dell’ Instituto of that year. The emperors Commodus and Caracalla were particularly given to the worship of Egyptian deities, and the emperor Alexander Severus is said to have bestowed additional decorations upon those temples. The third temple, that of Minerva Chalcidica, which was restored by Domitian, together with the Iseum and Serapeum after the fire in A.D. 80, stood nearer to the Pantheon, and probably occupied the site of the present church called S. Maria sopra Minerva. The statue of Minerva, formerly in the Giustiniani Palace and now placed in the Braccio Nuovo of the Vatican, was found here. Some few remains of pilasters which are built into the foundations of the houses between the Via della Minerva and the Via di pie di Marmo may have belonged to this temple. [Illustration: Pantheon.] [Sidenote: Pantheon.] At the same time with his Thermæ, which occupied this district, Agrippa built the famous dome, called by Pliny and Dion, and in the inscription of Severus on the architrave of the building itself, the Pantheon, and still retaining that name, though now consecrated as a Christian Church under the name of S. Maria ad Martyres or della Rotunda. This consecration, together with the colossal thickness of the walls, have secured the building against the waste of time, and the still more destructive attacks of the barons of the Middle Ages, who destroyed most of the other great edifices of imperial Rome by either making them their strongholds or pulling them down for building materials. The pronaos rests upon sixteen granite columns, with marble Corinthian bases and capitals. It was formerly approached by six steps, but two only are now above the level of the surrounding ground. The architrave and frieze are plain, and on the latter stands the inscription, which formerly, as may be seen by the holes for nails, was formed by metallic letters: M . AGRIPPA . L . F . COS . TERTIUM . FECIT.
